About This Reference
Red Hat Directory Server (Directory Server) is a powerful and scalable distributed directory server based on the industry-standard Lightweight Directory Access Protocol (LDAP). Directory Server is the cornerstone for building a centralized and distributed data repository that can be used in an intranet, over an extranet with trading partners, or over the public Internet to reach customers.
This reference covers the server configuration and the command-line utilities. It is designed primarily for directory administrators and experienced directory users who want to use the command-line to access the directory. After configuring the server, use this reference to help maintain it.
The Directory Server can also be managed through the Directory Server Console, a graphical user interface. The Red Hat Directory Server Administrator's Guide describes how to do this and explains individual administration tasks more fully.
1. Directory Server Overview
The major components of Directory Server include:
• An LDAP server – The LDAP v3-compliant network daemon.
• Directory Server Console – A graphical management console that dramatically reduces the effort of setting up and maintaining your directory service.
• SNMP agent – Can monitor the Directory Server using the Simple Network Management Protocol
(SNMP).
2. Examples and Formatting
Each of the examples used in this guide, such as file locations and commands, have certain defined conventions.
2.1. Command and File Examples
All of the examples for Red Hat Directory Server commands, file locations, and other usage are given for Red Hat Enterprise Linux 5 (32-bit) systems. Be certain to use the appropriate commands and files for your platform.
To start the Red Hat Directory Server: service dirsv start
Example 1. Example Command
2.2. Tool Locations
The tools for Red Hat Directory Server are located in the /usr/bin and the /usr/sbin directories.
These tools can be run from any location without specifying the tool location.
2.3. LDAP Locations
There is another important consideration with the Red Hat Directory Server tools. The LDAP tools referenced in this guide are Mozilla LDAP, installed with Red Hat Directory Server in the /usr/lib/ ix
About This Reference mozldap directory on Red Hat Enterprise Linux 5 (32-bit) (or /usr/lib64/mozldap for 64-bit systems).
However, Red Hat Enterprise Linux systems also include LDAP tools from OpenLDAP in the /usr/ bin directory. It is possible to use the OpenLDAP commands as shown in the examples, but you must use the -x argument to disable SASL, which OpenLDAP tools use by default.
2.4. Text Formatting and Styles
Certain words are represented in different fonts, styles, and weights. Different character formatting is used to indicate the function or purpose of the phrase being highlighted.
Formatting Style
Monospace font
Monospace with a background
Italicized text
Purpose
Monospace is used for commands, package names, files and directory paths, and any text displayed in a prompt.
This type of formatting is used for anything entered or returned in a command prompt.
Bolded text
Any text which is italicized is a variable, such as instance_name or hostname. Occasionally, this is also used to emphasize a new term or other phrase.
Most phrases which are in bold are application names, such as Cygwin, or are fields or options in a user interface, such as a User
Name Here: field or Save button.
Other formatting styles draw attention to important text.
NOTE
A note provides additional information that can help illustrate the behavior of the system or provide more detail for a specific issue.
IMPORTANT
Important information is necessary, but possibly unexpected, such as a configuration change that will not persist after a reboot.
WARNING
A warning indicates potential data loss, as may happen when tuning hardware for maximum performance.

Introduction
Directory Server is based on an open-systems server protocol called the Lightweight Directory Access
Protocol (LDAP). The Directory Server is a robust, scalable server designed to manage large scale directories to support an enterprise-wide directory of users and resources, extranets, and e-commerce applications over the Internet. The Directory Server runs as the ns-slapd process or service on the machine. The server manages the directory databases and responds to client requests.
This reference deals with the other methods of managing the Directory Server by altering the server configuration attributes using the command line and using command-line utilities and scripts.
1.1. Directory Server Configuration
The format and method for storing configuration information for Directory Server and a listing for all
server attributes are found in two chapters, Chapter 2, Core Server Configuration Reference and
Chapter 3, Plug-in Implemented Server Functionality Reference
.
1.2. Directory Server Instance File Reference
Chapter 4, Server Instance File Reference has an overview of the files and configuration information
stored in each instance of Directory Server. This is useful reference to helps administrators understand the changes or absence of changes in the course of directory activity. From a security standpoint, this also helps users detect errors and intrusion by highlighting normal changes and abnormal behavior.
1.3. Using Directory Server Command-Line Utilities
Directory Server comes with a set of configurable command-line utilities that can search and modify
entries in the directory and administer the server. Chapter 6, Command-Line Utilities
describes these command-line utilities and contains information on where the utilities are stored and how to access them. In addition to these command-line utilities, Directory Server also provides ns-slapd commandline utilities for performing directory operations, as described in
Appendix A, Using the ns-slapd
1.4. Using Directory Server Command-Line Scripts
In addition to command-line utilities, several non-configurable scripts are provided with the Directory
Server that make it quick and easy to perform routine server administration tasks from the command-
line. Chapter 7, Command-Line Scripts
lists the most frequently used scripts and contains information on where the scripts are stored and how to access them.

Chapter 2.
Core Server Configuration Reference
The configuration information for Red Hat Directory Server is stored as LDAP entries within the directory itself. Therefore, changes to the server configuration must be implemented through the use of the server itself rather than by simply editing configuration files. The principal advantage of this method of configuration storage is that it allows a directory administrator to reconfigure the server using LDAP while it is still running, thus avoiding the need to shut the server down for most configuration changes.
This chapter gives details on how the configuration is organized and how to alter it. The chapter also provides an alphabetical reference for all attributes.
2.1. Overview of the Directory Server Configuration
When the Directory Server is set up, its default configuration is stored as a series of LDAP entries within the directory, under the subtree cn=config. When the server is started, the contents of the cn=config subtree are read from a file (dse.ldif) in LDIF format. This dse.ldif file contains all of the server configuration information. The latest version of this file is called dse.ldif, the version prior to the last modification is called dse.ldif.bak, and the latest file with which the server successfully started is called dse.ldif.startOK.
Many of the features of the Directory Server are designed as discrete modules that plug into the core server. The details of the internal configuration for each plug-in are contained in separate entries under cn=plugins,cn=config. For example, the configuration of the Telephone Syntax Plug-in is contained in this entry: cn=Telephone Syntax,cn=plugins,cn=config
Similarly, database-specific configuration is stored under cn=ldbm database,cn=plugins,cn=config for local databases and cn=chaining database,cn=plugins,cn=config for database links.
The following diagram illustrates how the configuration data fits within the cn=config directory information tree.
Figure 2.1. Directory Information Tree Showing Configuration Data
2.1.1. LDIF and Schema Configuration Files
The Directory Server configuration data are stored in LDIF files in the /etc/dirsrv/ slapd-instance_name directory (/etc/opt/dirsrv/slapd-instance_name on HP-UX). Thus,
3
Chapter 2. Core Server Configuration Reference if a server identifier is phonebook, then for a Directory Server on Red Hat Enterprise Linux 5 (32-bit), the configuration LDIF files are all stored under /etc/dirsrv/slapd-phonebook.
This directory also contains other server instance-specific configuration files.
Schema configuration is also stored in LDIF format, and these files are located in the /etc/dirsrv/ slapd-instance_name/schema directory (/etc/opt/dirsrv/slapd->instance_name on HP-
UX).
The following table lists all of the configuration files that are supplied with the Directory Server, including those for the schema of other compatible servers. Each file is preceded by a number which indicates the order in which they should be loaded (in ascending numerical and then alphabetical order).
Configuration Filename dse.ldif
00core.ldif
01common.ldif
05rfc2247.ldif
05rfc2927.ldif
10presence.ldif
Purpose
Contains front-end Directory Specific Entries created by the directory at server startup. These include the Root DSE ("") and the contents of cn=config and cn=monitor (ACIs only).
Contains only those schema definitions necessary for starting the server with the bare minimum feature set (no user schema, no schema for any non-core features). The rest of the schema used by users, features, and applications is found in 01common.ldif and the other schema files. Do not modify this file.
Contains LDAPv3 standard operational schema, such as subschemaSubentry, LDAPv3 standard user and organization schema defined in RFC 2256 (based on X.520/X.521), inetOrgPerson and other widely-used attributes, and the operational attributes used by
Directory Server configuration. Modifying this file causes interoperability problems. User-defined attributes should be added through the Directory
Server Console.
Schema from RFC 2247 and related pilot schema, from "Using Domains in LDAP/X500
Distinguished Names."
Schema from RFC 2927, "MIME Directory Profile for LDAP Schema." Contains the ldapSchemas operational attribute required for the attribute to show up in the subschema subentry.
Legacy. Schema for instant messaging presence
(online) information; the file lists the default object classes with the allowed attributes that must be added to a user's entry in order for instant-messaging presence information to be available for that user.

LDAP as a Network Information Service." This may be superseded by 10rfc2307bis, the new version of rfc2307, when that schema becomes available.
Contains new schema elements and the Nortel subscriber interoperability specification. Also contains the adminRole and memberOf attributes and inetAdmin object class, previously stored in the 50ns-delegated- admin.ldif
file.
Schema from RFC 2713, "Schema for
Representing Java® Objects in an LDAP
Directory."
Contains pilot directory schema from RFC

Chapter 2. Core Server Configuration Reference
2.1.2. How the Server Configuration Is Organized
The dse.ldif file contains all configuration information including directory-specific entries created by the directory at server startup, such as entries related to the database. The file includes the root
Directory Server entry (or DSE, named by "") and the contents of cn=config and cn=monitor.
When the server generates the dse.ldif file, it lists the entries in hierarchical order in the order that the entries appear in the directory under cn=config, which is usually the same order in which an
LDAP search of subtree scope for base cn=config returns the entries.
dse.ldif
also contains the cn=monitor entry, which is mostly read-only, but can have ACIs set on it.
NOTE
The dse.ldif file does not contain every attribute in cn=config. If the attribute has not been set by the administrator and has a default value, the server will not write it to dse.ldif
. To see every attribute in cn=config, use ldapsearch.
2.1.2.1. Configuration Attributes
Within a configuration entry, each attribute is represented as an attribute name. The value of the attribute corresponds to the attribute's configuration.
The following code sample is an example of part of the dse.ldif file for a Directory Server. The example shows, among other things, that schema checking has been enabled; this is represented by the attribute nsslapd-schemacheck, which takes the value on.
dn: cn=config objectclass: top objectclass: extensibleObject objectclass: nsslapdConfig nsslapd-accesslog-logging-enabled: on nsslapd-enquote-sup-oc: off nsslapd-localhost: phonebook.example.com
nsslapd-schemacheck: on nsslapd-port: 389 nsslapd-localuser: nobody
...
2.1.2.2. Configuration of Plug-in Functionality
The configuration for each part of Directory Server plug-in functionality has its own separate entry and set of attributes under the subtree cn=plugins,cn=config. The following code sample is an example of the configuration entry for an example plug-in, the Telephone Syntax plug-in.
dn: cn=Telephone Syntax,cn=plugins,cn=config objectclass: top objectclass: nsSlapdPlugin objectclass: extensibleObject cn: Telephone Syntax nsslapd-pluginType: syntax nsslapd-pluginEnabled: on
6
Accessing and Modifying Server Configuration
Some of these attributes are common to all plug-ins, and some may be particular to a specific plug-in.
Check which attributes are currently being used by a given plug-in by performing an ldapsearch on the cn=config subtree.
For a list of plug-ins supported by Directory Server, general plug-in configuration information, the plugin configuration attribute reference, and a list of plug-ins requiring restart for configuration changes,
see Chapter 3, Plug-in Implemented Server Functionality Reference .
2.1.2.3. Configuration of Databases
The o=NetscapeRoot and cn=UserRoot subtrees under the database plug-in entry contain configuration data for the databases containing the o=NetscapeRoot suffix and the default suffix created during setup, such as dc=example,dc=com.
These entries and their children have many attributes used to configure different database settings, like the cache sizes, the paths to the index files and transaction logs, entries and attributes for monitoring and statistics; and database indexes.
2.1.2.4. Configuration of Indexes
Configuration information for indexing is stored as entries in the Directory Server under the following information-tree nodes:
• cn=index,o=NetscapeRoot,cn=ldbm database,cn=plugins,cn=config
• cn=index,cn=UserRoot,cn=ldbm database,cn=plugins,cn=config
• cn=default indexes,cn=config,cn=ldbm database,cn=plugins,cn=config
For more information about indexes in general, see the Directory Server Administrator's Guide. For
2.2. Accessing and Modifying Server Configuration
This section discusses access control for configuration entries and describes the various ways in which the server configuration can be viewed and modified. It also covers restrictions to the kinds of modification that can be made and discusses attributes that require the server to be restarted for changes to take effect.
2.2.1. Access Control for Configuration Entries
When the Directory Server is installed, a default set of access control instructions (ACIs) is implemented for all entries under cn=config. The following code sample is an example of these default ACIs.
aci: (targetattr = "*")(version 3.0; acl "Configuration Administrators Group"; allow (all)
groupdn = "ldap:///cn=Configuration Administrators,u=Groups, ou=TopologyManagement,
o=NetscapeRoot";) aci: (targetattr = "*")(version 3.0; acl "Configuration Administrator"; allow (all)
userdn = "ldap:///uid=admin, ou=Administrators, ou=TopologyManagement, o=NetscapeRoot";) aci: (targetattr = "*")(version 3.0; acl "Local Directory Administrators Group"; allow (all)
groupdn = "ldap:///ou=Directory Administrators, dc=example,dc=com";)
7
Chapter 2. Core Server Configuration Reference aci: (targetattr = "*")(version 3.0; acl "SIE Group"; allow(all)
groupdn = "ldap:///cn=slapd-phonebook, cn=Red Hat Directory Server,
cn=Server Group, cn=phonebook.example.com, dc=example,dc=com, o=NetscapeRoot";)
These default ACIs allow all LDAP operations to be carried out on all configuration attributes by the following users:
• Members of the Configuration Administrators group.
• The user acting as the administrator, the admin account that was configured at setup. By default, this is the same user account which is logged into the Console.
• Members of local Directory Administrators group.
• The SIE (Server Instance Entry) group, usually assigned using the Set Access Permissions process the main console.
For more information on access control, see the Directory Server Administrator's Guide.
2.2.2. Changing Configuration Attributes
Server attributes can be viewed and changed in one of three ways: through the Directory Server
Console, by performing ldapsearch and ldapmodify commands, or by manually editing the dse.ldif
file.
NOTE
Before editing the dse.ldif file, the server must be stopped; otherwise, the changes are lost. Editing the dse.ldif file is recommended only for changes to
attributes which cannot be altered dynamically. See Section 2.2.2.3, “Configuration
Changes Requiring Server Restart” for further information.
The following sections describe how to modify entries using LDAP (both by using Directory Server
Console and by using the command line), the restrictions that apply to modifying entries, the restrictions that apply to modifying attributes, and the configuration changes requiring restart.
2.2.2.1. Modifying Configuration Entries Using LDAP
The configuration entries in the directory can be searched and modified using LDAP either via the
Directory Server Console or by performing ldapsearch and ldapmodify operations in the same way as other directory entries. The advantage of using LDAP to modify entries is changes can be made while the server is running.
For further information, see the "Creating Directory Entries" chapter in the Directory Server
Administrator's Guide. However, certain changes do require the server to be restarted before they are taken into account. See
Section 2.2.2.3, “Configuration Changes Requiring Server Restart”
for further information.
NOTE
As with any set of configuration files, care should be taken when changing or deleting nodes in the cn=config subtree as this risks affecting Directory Server functionality.
8
Changing Configuration Attributes
The entire configuration, including attributes that always take default values, can be viewed by performing an ldapsearch operation on the cn=config subtree: ldapsearch -b cn=config -D bindDN -w password
• bindDN is the DN chosen for the Directory Manager when the server was installed (cn=Directory
Manager by default).
• password is the password chosen for the Directory Manager.
For more information on using ldapsearch, see
.
To disable a plug-in, use ldapmodify to edit the nsslapd-pluginEnabled attribute: ldapmodify -D cn="directory manager" -w password dn: cn=Telephone Syntax,cn=plugins,cn=config changetype: modify replace: nsslapd-pluginEnabled nsslapd-pluginEnabled: off
2.2.2.2. Restrictions to Modifying Configuration Entries and Attributes
Certain restrictions apply when modifying server entries and attributes:
• The cn=monitor entry and its child entries are read-only and cannot be modified, except to manage ACIs.
• If an attribute is added to cn=config, the server ignores it.
• If an invalid value is entered for an attribute, the server ignores it.
• Because ldapdelete is used for deleting an entire entry, use ldapmodify to remove an attribute from an entry.
2.2.2.3. Configuration Changes Requiring Server Restart
Some configuration attributes cannot be altered while the server is running. In these cases, for the changes to take effect, the server needs to be shut down and restarted. The modifications should be made either through the Directory Server Console or by manually editing the dse.ldif file.
Some of the attributes that require a server restart for any changes to take effect are listed below.
This list is not exhaustive; to see a complete list, run ldapsearch and search for the nsslapd- requiresrestart attribute. For example: ldapsearch -p 389 -D "cn=directory manager" -w password -s sub -b "cn=config"
"(objectclass=*)" | grep nsslapd-requiresrestart nsslapd-cachesize nsslapd-dbcachesize nsslapd-plugin nsslapd-changelogmaxage nsslapd-port nsslapd-saslpath nsslapd-certdir nsslapd-dbncache nsslapd-changelogdir nsslapd-changelogmaxentries nsslapd-schemadir nsslapd-secureport

2.3. Core Server Configuration Attributes Reference
This section contains reference information on the configuration attributes that are relevant to the core
see Section 3.1, “Server Plug-in Functionality Reference”
. For help with implementing custom server functionality, contact Directory Server support.
The configuration information stored in the dse.ldif file is organized as an information tree under the general configuration entry cn=config, as shown in the following diagram.
Figure 2.2. Directory Information Tree Showing Configuration Data
Most of these configuration tree nodes are covered in the following sections.
The cn=plugins node is covered in
Chapter 3, Plug-in Implemented Server Functionality Reference
.
The description of each attribute contains details such as the DN of its directory entry, its default value, the valid range of values, and an example of its use.
NOTE
Some of the entries and attributes described in this chapter may change in future releases of the product.
2.3.1. cn=config
General configuration entries are stored in the cn=config entry. The cn=config entry is an instance of the nsslapdConfig object class, which in turn inherits from extensibleObject object class.
10
cn=config
2.3.1.1. nsslapd-accesslog (Access Log)
This attribute specifies the path and filename of the log used to record each LDAP access. The following information is recorded by default in the log file:

2.3.1.4. nsslapd-accesslog-logbuffering (Log Buffering)
When set to off, the server writes all access log entries directly to disk. Buffering allows the server to use access logging even when under a heavy load without impacting performance. However, when debugging, it is sometimes useful to disable buffering in order to see the operations and their results right away instead of having to wait for the log entries to be flushed to the file. Disabling log buffering can severely impact performance in heavily loaded servers.

Space)
This attribute specifies the maximum amount of disk space in megabytes that the access logs are allowed to consume. If this value is exceeded, the oldest access log is deleted.
When setting a maximum disk space, consider the total number of log files that can be created due to log file rotation. Also, remember that there are three different log files (access log, audit log, and error log) maintained by the Directory Server, each of which consumes disk space. Compare these considerations to the total amount of disk space for the access log.

2.3.1.10. nsslapd-accesslog-logrotationsync-enabled (Access Log
Rotation Sync Enabled)
This attribute sets whether access log rotation is to be synchronized with a particular time of the day.
Synchronizing log rotation this way can generate log files at a specified time during a day, such as midnight to midnight every day. This makes analysis of the log files much easier because they then map directly to the calendar.
For access log rotation to be synchronized with time-of-day, this attribute must be enabled with the nsslapd-accesslog-logrotationsynchour and nsslapd-accesslog- logrotationsyncmin attribute values set to the hour and minute of the day for rotating log files.
For example, to rotate access log files every day at midnight, enable this attribute by setting its value to on, and then set the values of the nsslapd-accesslog-logrotationsynchour and nsslapd-accesslog-logrotationsyncmin attributes to 0.

2.3.1.13. nsslapd-accesslog-logrotationtime (Access Log Rotation Time)
This attribute sets the time between access log file rotations. The access log is rotated when this time interval is up, regardless of the current size of the access log. This attribute supplies only the number of units. The units (day, week, month, and so forth) are given by the nsslapd-accesslog- logrotationtimeunit attribute.
Although it is not recommended for performance reasons to specify no log rotation since the log grows indefinitely, there are two ways of specifying this. Either set the nsslapd-accesslog- maxlogsperdir attribute value to 1 or set the nsslapd-accesslog-logrotationtime attribute to -1. The server checks the nsslapd-accesslog-maxlogsperdir attribute first, and, if this attribute value is larger than 1, the server then checks the nsslapd-accesslog- logrotationtime
attribute. See Section 2.3.1.16, “nsslapd-accesslog-maxlogsperdir (Access Log

2.3.1.15. nsslapd-accesslog-maxlogsize (Access Log Maximum Log Size)
This attribute sets the maximum access log size in megabytes. When this value is reached, the access log is rotated. That means the server starts writing log information to a new log file. If the nsslapd- accesslog-maxlogsperdir attribute is set to 1, the server ignores this attribute.
When setting a maximum log size, consider the total number of log files that can be created due to log file rotation. Also, remember that there are three different log files (access log, audit log, and error log) maintained by the Directory Server, each of which consumes disk space. Compare these considerations to the total amount of disk space for the access log.

2.3.1.16. nsslapd-accesslog-maxlogsperdir (Access Log Maximum
Number of Log Files)
This attribute sets the total number of access logs that can be contained in the directory where the access log is stored. Each time the access log is rotated, a new log file is created. When the number of files contained in the access log directory exceeds the value stored in this attribute, then the oldest version of the log file is deleted. For performance reasons, Red Hat recommends not setting this value to 1 because the server does not rotate the log, and it grows indefinitely.
If the value for this attribute is higher than 1, then check the nsslapd-accesslog- logrotationtime attribute to establish whether log rotation is specified. If the nsslapd- accesslog-logrotationtime attribute has a value of -1, then there is no log rotation. See

2.3.1.17. nsslapd-accesslog-mode (Access Log File Permission)
This attribute sets the access mode or file permission with which access log files are to be created.
The valid values are any combination of 000 to 777 (these mirror the numbered or absolute UNIX file permissions). The value must be a 3-digit number, the digits varying from 0 through 7:
• 0 - None
• 1 - Execute only
• 2 - Write only
• 3 - Write and execute
• 4 - Read only
• 5 - Read and execute
• 6 - Read and write
• 7 - Read, write, and execute
In the 3-digit number, the first digit represents the owner's permissions, the second digit represents the group's permissions, and the third digit represents everyone's permissions. When changing the default value, remember that 000 does not allow access to the logs and that allowing write permissions to everyone can result in the logs being overwritten or deleted by anyone.
The newly configured access mode only affects new logs that are created; the mode is set when the log rotates to a new file.

18
cn=config
/usr/lib/mozldap/ldapsearch -D "cn=directory manager" -b "dc=example,dc=com" -s sub
"(objectclass=*)"
When unauthenticated binds are allowed, the bind attempt goes through as an anonymous bind
(assuming anonymous access is allowed).

2.3.1.36. nsslapd-certmap-basedn (Certificate Map Search Base)
This attribute can be used when client authentication is performed using SSL certificates in order to avoid limitations of the security subsystem certificate mapping, configured in the certmap.conf file. Depending on the certmap.conf configuration, the certificate mapping may be done using a directory subtree search based at the root DN. If the search is based at the root DN, then the nsslapd-certmap-basedn attribute may force the search to be based at some entry other than the root. The valid value for this attribute is the DN of the suffix or subtree to use for certificate mapping.

Integer nsslapd-conntablesize: 4093
Increase the value of this attribute if Directory Server is refusing connections because it is out of connection slots. When this occurs, the Directory Server's error log file records the message Not listening for new connections -- too many fds open .
A server restart is required for the change to take effect.
It may be necessary to increase the operating system limits for the number of open files and number of open files per process, and it may be necessary to increase the ulimit for the number of open
2.3.1.39. nsslapd-counters
The nsslapd-counters attribute enables and disables Directory Server database and server performance counters.
There can be a performance impact by keeping track of the larger counters. Turning off 64-bit integers for counters can have a minimal improvement on performance, although it negatively affects long term statistics tracking.
This parameter is enabled by default. To disable counters, stop the Directory Server, edit the dse.ldif
file directly, and restart the server.

2.3.1.49. nsslapd-errorlog-logmaxdiskspace (Error Log Maximum Disk
Space)
This attribute sets the maximum amount of disk space in megabytes that the error logs are allowed to consume. If this value is exceeded, the oldest error log is deleted.
When setting a maximum disk space, consider the total number of log files that can be created due to log file rotation. Also, remember that there are three different log files (access log, audit log, and error log) maintained by the Directory Server, each of which consumes disk space. Compare these considerations to the total amount of disk space for the error log.
Parameter

2.3.1.51. nsslapd-errorlog-logrotationsync-enabled (Error Log Rotation
Sync Enabled)
This attribute sets whether error log rotation is to be synchronized with a particular time of the day.
Synchronizing log rotation this way can generate log files at a specified time during a day, such as midnight to midnight every day. This makes analysis of the log files much easier because they then map directly to the calendar.
For error log rotation to be synchronized with time-of-day, this attribute must be enabled with the nsslapd-errorlog-logrotationsynchour and nsslapd-errorlog-logrotationsyncmin attribute values set to the hour and minute of the day for rotating log files.
For example, to rotate error log files every day at midnight, enable this attribute by setting its value to on , and then set the values of the nsslapd-errorlog-logrotationsynchour and nsslapd- errorlog-logrotationsyncmin attributes to 0.

2.3.1.54. nsslapd-errorlog-logrotationtime (Error Log Rotation Time)
This attribute sets the time between error log file rotations. The error log is rotated when this time interval is up, regardless of the current size of the error log. This attribute supplies only the number of units. The units (day, week, month, and so forth) are given by the nsslapd-errorlog- logrotationtimeunit (Error Log Rotation Time Unit) attribute.
Although it is not recommended for performance reasons to specify no log rotation, as the log grows indefinitely, there are two ways of specifying this. Either set the nsslapd-errorlog- maxlogsperdir attribute value to 1 or set the nsslapd-errorlog-logrotationtime attribute to
-1 . The server checks the nsslapd-errorlog-maxlogsperdir attribute first, and, if this attribute value is larger than 1, the server then checks the nsslapd-errorlog-logrotationtime attribute.

2.3.1.56. nsslapd-errorlog-maxlogsize (Maximum Error Log Size)
This attribute sets the maximum error log size in megabytes. When this value is reached, the error log is rotated, and the server starts writing log information to a new log file. If nsslapd-errorlog- maxlogsperdir is set to 1, the server ignores this attribute.
When setting a maximum log size, consider the total number of log files that can be created due to log file rotation. Also, remember that there are three different log files (access log, audit log, and error log) maintained by the Directory Server, each of which consumes disk space. Compare these considerations to the total amount of disk space for the error log.

2.3.1.57. nsslapd-errorlog-maxlogsperdir (Maximum Number of Error Log
Files)
This attribute sets the total number of error logs that can be contained in the directory where the error log is stored. Each time the error log is rotated, a new log file is created. When the number of files contained in the error log directory exceeds the value stored on this attribute, then the oldest version of the log file is deleted. The default is 1 log. If this default is accepted, the server does not rotate the log, and it grows indefinitely.
If the value for this attribute is higher than 1, then check the nsslapd-errorlog- logrotationtime attribute to establish whether log rotation is specified. If the nsslapd- errorlog-logrotationtime attribute has a value of -1, then there is no log rotation. See

2.3.1.58. nsslapd-errorlog-mode (Error Log File Permission)
This attribute sets the access mode or file permissions with which error log files are to be created.
The valid values are any combination of 000 to 777 since they mirror numbered or absolute UNIX file permissions. That is, the value must be a combination of a 3-digit number, the digits varying from 0 through 7:
• 0 - None
• 1 - Execute only
• 2 - Write only
• 3 - Write and execute
• 4 - Read only
• 5 - Read and execute
• 6 - Read and write
• 7 - Read, write, and execute
In the 3-digit number, the first digit represents the owner's permissions, the second digit represents the group's permissions, and the third digit represents everyone's permissions. When changing the default value, remember that 000 does not allow access to the logs and that allowing write permissions to everyone can result in the logs being overwritten or deleted by anyone.
The newly configured access mode only affects new logs that are created; the mode is set when the log rotates to a new file.

2.3.1.60. nsslapd-idletimeout (Default Idle Timeout)
This attribute sets the amount of time in seconds after which an idle LDAP client connection is closed by the server. A value of 0 means that the server never closes idle connections. This setting applies to all connections and all users. Idle timeout is enforced when the connection table is walked, when poll() does not return zero. Therefore, a server with a single connection never enforces the idle timeout.
Use the nsIdleTimeout operational attribute, which can be added to user entries, to override the value assigned to this attribute. For details, see the "Setting Resource Limits Based on the Bind DN" section in the Directory Server Administrator's Guide.
NOTE
For very large databases, with millions of entries, this attribute must have a high enough value that the online initialization process can complete or replication will fail when the connection to the server times out. Alternatively, the nsIdleTimeout attribute can be set to a high value on the entry used as the supplier bind DN.

This attribute sets whether the Directory Server maintains the modification attributes for Directory
Server entries. These are operational attributes. These attributes include:
• modifiersName - The distinguished name of the person who last modified the entry.
• modifyTimestamp - The timestamp, in GMT format, for when the entry was last modified.
• creatorsName - The distinguished name of the person who initially created the entry.
• createTimestamp - The timestamp for when the entry was created in GMT format.

WARNING
This attribute should never be turned off. If the nsslapd-lastmod is set to off, then generating nsUniqueIDs is also disabled, replication does not work, and other issues may arise.
If for some reason this attribute were set to off, the solution is to export the database to ldif (db2ldif or db2ldif.pl or from the console), set the value to on, and import the data. The import process assigns each entry a unique id.
2.3.1.64. nsslapd-ldapiautobind (Enable Autobind)
The nsslapd-ldapiautobind sets whether the server will allow users to autobind to Directory
Server using LDAPI. Autobind maps the UID or GUID number of a system user to a Directory Server user, and automatically authenticates the user to Directory Server based on those credentials. The
Directory Server connection occurs over UNIX socket.
Along with enabling autobind, configuring autobind requires configuring mapping entries. The nsslapd-ldapimaprootdn maps a root user on the system to the Directory Manager. The nsslapd-ldapimaptoentries maps regular users to Directory Server users, based on the parameters defined in the nsslapd-ldapiuidnumbertype, nsslapd-ldapigidnumbertype, and nsslapd-ldapientrysearchbase attributes.
Autobind can only be enabled if LDAPI is enabled, meaning the nsslapd-ldapilisten is on and the nsslapd-ldapifilepath attribute is set to an LDAPI socket.

2.3.1.65. nsslapd-ldapientrysearchbase (Search Base for LDAPI
Authentication Entries)
With autobind, it is possible to map system users to Directory Server user entries, based on the system user's UID and GUID numbers. This requires setting Directory Server parameters for which attribute to use for the UID number (nsslapd-ldapiuidnumbertype) and GUID number
(nsslapd-ldapigidnumbertype) and setting the search base to use to search for matching user entries.
The nsslapd-ldapientrysearchbase gives the subtree to search for user entries to use for autobind.

2.3.1.67. nsslapd-ldapigidnumbertype (Attribute Mapping for System
GUID Number)
Autobind can be used to authenticate system users to the server automatically and connect to the server using a UNIX socket. To map the system user to a Directory Server user for authentication, the system user's UID and GUID numbers should be mapped to be a Directory Server attribute. The nsslapd-ldapigidnumbertype attribute points to the Directory Server attribute to map system
GUIDs to user entries.
Users can only connect to the server with autobind if LDAPI is enabled (nsslapd-ldapilisten and nsslapd-ldapifilepath), autobind is enabled (nsslapd-ldapiautobind), and autobind mapping is enabled for regular users (nsslapd-ldapimaptoentries).

2.3.1.70. nsslapd-ldapimaptoentries (Enable Autobind Mapping for
Regular Users)
With autobind, a system user is mapped to a Directory Server user and then automatically authenticated to the Directory Server over a UNIX socket. This mapping is automatic for root users, but it must be enabled for regular system users through the nsslapd-ldapimaptoentries attribute. Setting this attribute to on enables mapping for regular system users to Directory Server entries. If this attribute is not enabled, then only root users can use autobind to authenticate to the
Directory Server, and all other users connect anonymously.
The mappings themselves are configured through the nsslapd-ldapiuidnumbertype and nsslapd-ldapigidnumbertype attributes, which map Directory Server attributes to the user's UID and GUID numbers.
Users can only connect to the server with autobind if LDAPI is enabled (nsslapd-ldapilisten and nsslapd-ldapifilepath ) and autobind is enabled (nsslapd-ldapiautobind).

2.3.1.72. nsslapd-listenhost (Listen to IP Address)
This attribute allows multiple Directory Server instances to run on a multihomed machine (or makes it possible to limit listening to one interface of a multihomed machine). There can be multiple IP addresses associated with a single hostname, and these IP addresses can be a mix of both IPv4 and
IPv6. This parameter can be used to restrict the Directory Server instance to a single IP interface.
If a hostname is given as the nsslapd-listenhost value, then the Directory Server responds to requests for every interface associated with the hostname. If a single IP interface (either IPv4 or IPv6) is given as the nsslapd-listenhost value, Directory Server only responds to requests sent to that specific interface. Either an IPv4 or IPv6 address can be used.
The server has to be restarted for changes to this attribute to go into effect.

2.3.1.76. nsslapd-maxbersize (Maximum Message Size)
Defines the maximum size in bytes allowed for an incoming message. This limits the size of LDAP requests that can be handled by the Directory Server. Limiting the size of requests prevents some kinds of denial of service attacks.
The limit applies to the total size of the LDAP request. For example, if the request is to add an entry and if the entry in the request is larger than two megabytes, then the add request is denied. Be cautious before changing this attribute.
The server should be restarted for changes in this attribute to take effect.

2.3.1.77. nsslapd-maxdescriptors (Maximum File Descriptors)
This attribute sets the maximum, platform-dependent number of file descriptors that the Directory
Server tries to use. A file descriptor is used whenever a client connects to the server and also for some server activities, such as index maintenance. File descriptors are also used by access logs, error logs, audit logs, database files (indexes and transaction logs), and as sockets for outgoing connections to other servers for replication and chaining.
The number of descriptors available for TCP/IP to serve client connections is determined by nsslapd-conntablesize , and is equal to the nsslapd-maxdescriptors attribute minus the number of file descriptors used by the server as specified in the nsslapd-reservedescriptors attribute for non-client connections, such as index management and managing replication. The nsslapd-reservedescriptors attribute is the number of file descriptors available for other uses as described above. See
Section 2.3.1.89, “nsslapd-reservedescriptors (Reserved File Descriptors)”
.
The number given here should not be greater than the total number of file descriptors that the operating system allows the ns-slapd process to use. This number differs depending on the operating system.
If this value is set too high, the Directory Server queries the operating system for the maximum allowable value, and then use that value. It also issues a warning in the error log. If this value is set to an invalid value remotely, by using the Directory Server Console or ldapmodify, the server rejects the new value, keep the old value, and respond with an error.
Some operating systems let users configure the number of file descriptors available to a process.
See the operating system documentation for details on file descriptor limits and configuration. The dsktune program (explained in the Directory Server Installation Guide) can be used to suggest changes to the system kernel or TCP/IP tuning attributes, including increasing the number of file descriptors if necessary. Increased the value on this attribute if the Directory Server is refusing connections because it is out of file descriptors. When this occurs, the following message is written to the Directory Server's error log file:
Not listening for new connections -- too many fds open
See
Section 2.3.1.38, “nsslapd-conntablesize” for more information about increasing the number of
incoming connections.
NOTE
UNIX shells usually have configurable limits on the number of file descriptors. See the operating system documentation for further information about limit and ulimit, as these limits can often cause problems.
The server has to be restarted for changes to this attribute to go into effect.

2.3.1.78. nsslapd-maxsasliosize (Maximum SASL Packet Size)
When a user is authenticated to the Directory Server over SASL GSS-API, the server must allocate a certain amount of memory to the client to perform LDAP operations, according to how much memory the client requests. It is possible for an attacker to send such a large packet size that it crashes the
Directory Server or ties it up indefinitely as part of a denial of service attack.
The packet size which the Directory Server will allow for SASL clients can be limited using the nsslapd-maxsasliosize attribute. This attribute sets the maximum allowed SASL IO packet size that the server will accept.
When an incoming SASL IO packet is larger than the nsslapd-maxsasliosize limit, the server immediately disconnects the client and logs a message to the error log, so that an administrator can adjust the setting if necessary.
This attribute value is specified in bytes.

Defines the maximum number of threads that a connection should use. For normal operations where a client binds and only performs one or two operations before unbinding, use the default value. For situations where a client binds and simultaneously issues many requests, increase this value to allow each connection enough resources to perform all the operations. This attribute is not available from the server console.

This read-only attribute lists the DNs of the plug-in entries for the syntax and matching rule plug-ins loaded by the server.
2.3.1.83. nsslapd-port (Port Number)
This attribute gives the TCP/IP port number used for standard LDAP communications. To run SSL/TLS over this port, use the Start TLS extended operation. This selected port must be unique on the host system; make sure no other application is attempting to use the same port number. Specifying a port number of less than 1024 means the Directory Server has to be started as root.
The server sets its uid to the nsslapd-localuser value after startup. When changing the port number for a configuration directory, the corresponding server instance entry in the configuration directory must be updated.
The server has to be restarted for the port number change to be taken into account.

Turns fine-grained (subtree- and user-level) password policy on and off.
If this attribute has a value of off, all entries (except for cn=Directory Manager) in the directory is subjected to the global password policy; the server ignores any defined subtree/user level password policy.

2.3.1.87. nsslapd-referral (Referral)
This multi-valued attribute specifies the LDAP URLs to be returned by the suffix when the server receives a request for an entry not belonging to the local tree; that is, an entry whose suffix does not match the value specified on any of the suffix attributes. For example, assume the server contains only entries: ou=People,dc=example,dc=com but the request is for this entry: ou=Groups,dc=example,dc=com
In this case, the referral would be passed back to the client in an attempt to allow the LDAP client to locate a server that contains the requested entry. Although only one referral is allowed per Directory
Server instance, this referral can have multiple values.
NOTE
To use SSL and TLS communications, the referral attribute should be in the form ldaps:// server-location.
Start TLS does not support referrals.
For more information on managing referrals, see the "Configuring Directory Databases" chapter in the
Directory Server Administrator's Guide.

2.3.1.89. nsslapd-reservedescriptors (Reserved File Descriptors)
This attribute specifies the number of file descriptors that Directory Server reserves for managing non-client connections, such as index management and managing replication. The number of file descriptors that the server reserves for this purpose subtracts from the total number of file descriptors available for servicing LDAP client connections (See
Section 2.3.1.77, “nsslapd-maxdescriptors
).
Most installations of Directory Server should never need to change this attribute. However, consider increasing the value on this attribute if all of the following are true:
• The server is replicating to a large number of consumer servers (more than 10), and/or the server is maintaining a large number of index files (more than 30).
• The server is servicing a large number of LDAP connections.
• There are error messages reporting that the server is unable to open file descriptors (the actual error message differs depending on the operation that the server is attempting to perform), but these error messages are not related to managing client LDAP connections.
Increasing the value on this attribute may result in more LDAP clients being unable to access the directory. Therefore, the value on this attribute is increased, also increase the value on the nsslapd- maxdescriptors attribute. It may not be possible to increase the nsslapd-maxdescriptors value if the server is already using the maximum number of file descriptors that the operating system allows a process to use; see the operating system documentation for details. If this is the case, then reduce the load on the server by causing LDAP clients to search alternative directory replicas. See
Section 2.3.1.38, “nsslapd-conntablesize” for information about file descriptor usage for incoming
connections.
To assist in computing the number of file descriptors set for this attribute, use the following formula: nsslapd-reservedescriptor = 20 + (NldbmBackends * 4) + NglobalIndex +
ReplicationDescriptor + ChainingBackendDescriptors + PTADescriptors + SSLDescriptors
• NldbmBackends is the number of ldbm databases.
• NglobalIndex is the total number of configured indexes for all databases including system indexes.
(By default 8 system indexes and 17 additional indexes per database).
• ReplicationDescriptor is eight (8) plus the number of replicas in the server that can act as a supplier or hub (NSupplierReplica).
49
Chapter 2. Core Server Configuration Reference
• ChainingBackendDescriptors is NchainingBackend times the nsOperationConnectionsLimit (a chaining or database link configuration attribute; 10 by default).
• PTADescriptors is 3 if PTA is configured and 0 if PTA is not configured.
• SSLDescriptors is 5 (4 files + 1 listensocket) if SSL is configured and 0 if SSL is not configured.
The server has to be restarted for changes to this attribute to go into effect.

2.3.1.90. nsslapd-return-exact-case (Return Exact Case)
Returns the exact case of attribute type names as requested by the client. Although LDAPv3compliant clients must ignore the case of attribute names, some client applications require attribute names to match exactly the case of the attribute as it is listed in the schema when the attribute is returned by the Directory Server as the result of a search or modify operation. However, most client applications ignore the case of attributes; therefore, by default, this attribute is disabled. Do not modify it unless there are legacy clients that can check the case of attribute names in results returned from the server.
The server has to be restarted for changes to this attribute to go into effect.

1274 names. Set the value to on for those clients. The default is off.
2.3.1.92. nsslapd-rootdn (Manager DN)
This attribute sets the distinguished name (DN) of an entry that is not subject to access control restrictions, administrative limit restrictions for operations on the directory, or resource limits in general.
There does not have to be an entry corresponding to this DN, and by default there is not an entry for this DN, thus values like cn=Directory Manager are acceptable.

2.3.1.93. nsslapd-rootpw (Root Password)
This attribute sets the password associated with the Manager DN. When the root password is provided, it is encrypted according to the encryption method selected for the nsslapd- rootpwstoragescheme attribute. When viewed from the server console, this attribute shows the value *****. When viewed from the dse.ldif file, this attribute shows the encryption method followed by the encrypted string of the password. The example shows the password as displayed in the dse.ldif file, not the actual password.
WARNING
When the root DN is configured at server setup, a root password is required.
However, it is possible for the root password to be deleted from dse.ldif by directly editing the file. In this situation, the root DN can only obtain the same access to the directory is allowed for anonymous access. Always make sure that a root password is defined in dse.ldif when a root DN is configured for the database. The pwdhash command-line utility can create a new root password. For more information, see
Section 7.3.12, “pwdhash (Prints Encrypted Passwords)” .

2.3.1.95. nsslapd-saslpath
Sets the absolute path to the directory containing the Cyrus-SASL SASL2 plug-ins. On HP-UX systems, the Directory Server cannot use the system SASL libraries because they are either not provided or are not the correct version. Setting this attribute allows the server to use custom or nonstandard SASL plug-in libraries. This is usually set correctly during installation, and Red Hat strongly recommends not changing this attribute. If the attribute is not present or the value is empty, this means the Directory Server is using the system provided SASL plug-in libraries which are the correct version.
If this parameter is set, the server uses the specified path for loading SASL plugins. If this parameter is not set, the server uses the SASL_PATH environment variable. If neither nsslapd-saslpath or
SASL_PATH are set, the server attempts to load SASL plugins from the default location, /usr/lib/ sasl2 .
Changes made to this attribute will not take effect until the server is restarted.

2.3.1.96. nsslapd-schema-ignore-trailing-spaces (Ignore Trailing Spaces in Object Class Names)
Ignores trailing spaces in object class names. By default, the attribute is turned off. If the directory contains entries with object class values that end in one or more spaces, turn this attribute on. It is preferable to remove the trailing spaces because the LDAP standards do not allow them.
For performance reasons, server restart is required for changes to take effect.
An error is returned by default when object classes that include trailing spaces are added to an entry.
Additionally, during operations such as add, modify, and import (when object classes are expanded and missing superiors are added) trailing spaces are ignored, if appropriate. This means that even when nsslapd-schema-ignore-trailing-spaces is on, a value such as top is not added if top is already there. An error message is logged and returned to the client if an object class is not found and it contains trailing spaces.

2.3.1.97. nsslapd-schemacheck (Schema Checking)
This attribute sets whether the database schema is enforced when entries are added or modified.
When this attribute has a value of on, Directory Server will not check the schema of existing entries until they are modified. The database schema defines the type of information allowed in the database.
The default schema can be extended using the object classes and attribute types. For information on how to extend the schema using the Directory Server Console, see the "Extending the Directory
Schema" chapter in the Directory Server Administrator's Guide.
WARNING
Red Hat strongly discourages turning off schema checking. This can lead to severe interoperability problems. This is typically used for very old or non-standard LDAP data that must be imported into the Directory Server. If there are not a lot of entries that have this problem, consider using the extensibleObject object class in those entries to disable schema checking on a per entry basis.
NOTE
Schema checking works by default when database modifications are made using an LDAP client, such as ldapmodify or when importing a database from LDIF using ldif2db. If schema checking is turned off, every entry has to be verified manually to see that they conform to the schema. If schema checking is turned on, the server sends an error message listing the entries which do not match the schema.
Ensure that the attributes and object classes created in the LDIF statements are both spelled correctly and identified in dse.ldif. Either create an LDIF file in the schema directory or add the elements to 99user.ldif.

2.3.1.98. nsslapd-schemadir
This is the absolute path to the directory containing the Directory Server instance-specific schema files. When the server starts up, it reads the schema files from this directory, and when the schema is modified through LDAP tools, the schema files in this directory are updated. This directory must
53
Chapter 2. Core Server Configuration Reference be owned by the server user ID, and that user must have read and write permissions to the directory.
The default value is the schema subdirectory of the Directory Server instance-specific configuration directory, /etc/dirsrv/slapd-instance_name/schema.
Changes made to this attribute will not take effect until the server is restarted.

2.3.1.100. nsslapd-securelistenhost
This attribute allows multiple Directory Server instances to run on a multihomed machine (or makes it possible to limit listening to one interface of a multihomed machine). There can be multiple IP addresses associated with a single hostname, and these IP addresses can be a mix of both IPv4 and
IPv6. This parameter can be used to restrict the Directory Server instance to a single IP interface; this parameter also specifically sets what interface to use for SSL/TLS traffic rather than regular LDAP connections.
If a hostname is given as the nsslapd-securelistenhost value, then the Directory Server responds to requests for every interface associated with the hostname. If a single IP interface (either
IPv4 or IPv6) is given as the nsslapd-securelistenhost value, Directory Server only responds to requests sent to that specific interface. Either an IPv4 or IPv6 address can be used.
The server has to be restarted for changes to this attribute to go into effect.

This attribute sets the TCP/IP port number used for SSL/TLS communications. This selected port must be unique on the host system; make sure no other application is attempting to use the same port number. Specifying a port number of less than 1024 requires that Directory Server be started as root . The server sets its uid to the nsslapd-localuser value after startup.
The server only listens to this port if it has been configured with a private key and a certificate, and nsslapd-security is set to on; otherwise, it does not listen on this port.

2.3.1.103. nsslapd-sizelimit (Size Limit)
This attribute sets the maximum number of entries to return from a search operation. If this limit is reached, ns-slapd returns any entries it has located that match the search request, as well as an exceeded size limit error.
When no limit is set, ns-slapd returns every matching entry to the client regardless of the number found. To set a no limit value whereby the Directory Server waits indefinitely for the search to complete, specify a value of -1 for this attribute in the dse.ldif file.
This limit applies to everyone, regardless of their organization.
NOTE
A value of -1 on this attribute in dse.ldif file is the same as leaving the attribute blank in the server console, in that it causes no limit to be used. This cannot have a null value in dse.ldif file, as it is not a valid integer. It is possible to set it to 0, which returns size limit exceeded for every search.

2.3.1.104. nsslapd-ssl-check-hostname (Verify Hostname for Outbound
Connections)
This attribute sets whether an SSL-enabled Directory Server should verify authenticity of a request by matching the hostname against the value assigned to the common name (cn) attribute of the subject name (subjectDN field) in the certificate being presented. By default, the attribute is set to on. If it is on and if the hostname does not match the cn attribute of the certificate, appropriate error and audit messages are logged.
For example, in a replicated environment, messages similar to the following are logged in the supplier server's log files if it finds that the peer server's hostname does not match the name specified in its certificate:
[DATE] - SSL alert: ldap_sasl_bind("",LDAP_SASL_EXTERNAL) 81 (Netscape runtime error -12276 -
Unable to communicate securely with peer: requested domain name does not
match the server's certificate.)
[DATE] NSMMReplicationPlugin - agmt="cn=SSL Replication Agreement to
host1" (host1.example.com:636):
Replication bind with SSL client authentication failed:
LDAP error 81 (Can't contact LDAP server)
Red Hat recommends turning this attribute on to protect Directory Server's outbound SSL connections against a man in the middle (MITM) attack.
NOTE>
DNS and reverse DNS must be set up correctly in order for this to work; otherwise, the server cannot resolve the peer IP address to the hostname in the subject DN in the certificate.

Defines the number of operation threads that the Directory Server creates at startup. The nsslapd- threadnumber value should be increased if there are many directory clients performing timeconsuming operations such as add or modify, as this ensures that there are other threads available for servicing short-lived operations such as simple searches. This value may also need increased if there are many replication agreements or chained backends (database links). This attribute is not available from the server console.

2.3.1.106. nsslapd-timelimit (Time Limit)
This attribute sets the maximum number of seconds allocated for a search request. If this limit is reached, Directory Server returns any entries it has located that match the search request, as well as an exceeded time limit error.
When no limit is set, ns-slapd returns every matching entry to the client regardless of the time it takes. To set a no limit value whereby Directory Server waits indefinitely for the search to complete, specify a value of -1 for this attribute in the dse.ldif file. A value of zero (0) causes no time to be allowed for searches. The smallest time limit is 1 second.
NOTE
A value of -1 on this attribute in thedse.ldif is the same as leaving the attribute blank in the server console in that it causes no limit to be used. However, a negative integer cannot be set in this field in the server console, and a null value cannot be used in the dse.ldif entry, as it is not a valid integer.

2.3.1.113. passwordCheckSyntax (Check Password Syntax)
This attribute sets whether the password syntax is checked before the password is saved. The password syntax checking mechanism checks that the password meets or exceeds the password minimum length requirement and that the string does not contain any trivial words, such as the user's name or user ID or any attribute value stored in the uid, cn, sn, givenname, ou, or mail attributes of the user's directory entry.
Password syntax includes several different categories for checking:
• Minimum number of digit characters (0-9)
• Minimum number of ASCII alphabetic characters, both upper- and lower-case
• Minimum number of uppercase ASCII alphabetic characters
• Minimum number of lowercase ASCII alphabetic characters
• Minimum number of special ASCII characters, such as !@#$
• Minimum number of 8-bit characters
• Maximum number of times that the same character can be immediately repeated, such as aaabbb
• Minimum number of character categories required per password; a category can be upper- or lowercase letters, special characters, digits, or 8-bit characters
This can be abbreviated to pwdCheckSyntax.

2.3.1.142. passwordStorageScheme (Password Storage Scheme)
This attribute sets the type of encryption used to store Directory Server passwords.
The following encryption types are supported by the Directory Server:
• CLEAR means the password is stored in cleartext, with no hashing or encryption. This scheme must be used in order to use SASL DIGEST-MD5.
• SSHA (Salted Secure Hash Algorithm), the default, is the recommended method because it is the most secure. There are several bit sizes available: 140 bits (the default), 256, 384, and 512.
• SHA (Secure Hash Algorithm) is included only for backward compatibility with 4.x Directory Servers; do not use this algorithm.
• MD5 (Message Digest algorithm 5) is a commonly used standard hashing algorithm.
• CRYPT, the UNIX crypt algorithm, is provided for compatibility with UNIX passwords.
NOTE
Passwords cannot be encrypted using the NS-MTA-MD5 password storage scheme.
The storage scheme is still present but only for reasons of backward compatibility.
For more information on password policies, see the "Managing Users and Passwords" chapter in the
Directory Server Administrator's Guide.
2.3.1.143. passwordUnlock (Unlock Account)

2.3.2. cn=changelog5
Multi-master replication changelog configuration entries are stored under the cn=changelog5 entry.
The changelog behaves much like a database, and it has many of attributes also used by the ldbm databases.
The primary cache-related memory attribute, nsslapd-cachememsize, has a default value of
10485760 bytes, which is 10 MB. This parameter is tuned for a single backend replicated to a single consumer.
When more backends are replicated or when one backend is replicated to more than one consumer, tune the nsslapd-cachememsize so that its value is 5000000 times the number of replication agreements initiated from the server (5000000 * no_of_repl_agreements).
The relationship between the values assigned to the nsslapd-dbcachesize and nsslapd- cachememsize parameters should be the same as the relationship that is described in the database tuning section.
The cn=changelog5,cn=config entry is an instance of the extensibleObject object class.
NOTE
Two different types of changelogs are maintained by Directory Server. The first type, which is stored here and referred to as the changelog, is used by multimaster replication; the second changelog, which is actually a plug-in and referred to as the retro changelog, is for compatibility with some legacy applications. See
Section 3.1.29, “Retro Changelog Plug-in”
for further information about the Retro
Changelog Plug-in.
2.3.2.1. nsslapd-changelogdir
This required attribute specifies the name of the directory in which the changelog database is created.
Whenever a changelog configuration entry is created, it must contain a valid directory; otherwise, the operation is rejected. The GUI proposes by default that this database be stored in /var/lib/ dirsrv/slapd-instance_name/changelogdb .
WARNING
If the cn=changelog5 entry is removed, the directory specified in the nsslapd- changelogdir parameter, including any subdirectories, are removed, with all of their contents.

2.3.5. cn=mapping tree
• Configuration attributes for suffixes, replication, and Windows synchronization are stored under cn=mapping tree,cn=config . Configuration attributes related to suffixes are found under the suffix subentry cn=suffix, cn=mapping tree,cn=config.
For example, a suffix is the root entry in the directory tree, such as dc=example,dc=com.
• Replication configuration attributes are stored under cn=replica, cn=suffix, cn=mapping tree,cn=config .
• Replication agreement attributes are stored under cn=replicationAgreementName, cn=replica, cn= suffix,cn=mapping tree,cn=config.
• Windows synchronization agreement attributes are stored under cn=syncAgreementName, cn=replica, cn= suffix,cn=mapping tree,cn=config.
2.3.6. Suffix Configuration Attributes under cn="suffixName"
Suffix configuration attributes are stored under the cn=suffix entry. The cn=suffix entry is an instance of the nsMappingTree object class which inherits from the extensibleObject object class. For suffix configuration attributes to be taken into account by the server, these object classes (in addition to the top object class) must be present in the entry.
The suffix DN should be quoted because the suffix DN contains characters such as equals signs (=), commas (,), and space characters that must be quoted or escaped to appear as a value in another
DN.
2.3.6.1. nsslapd-state
Determines how the suffix handles operations.
Parameter
Entry DN
Valid Values
Default Value
Syntax
Description cn=suffix, cn=mapping tree, cn=config backend | disabled | referral | referral on update
backend means the backend (database) is used to process all operations.
disabled means the database is not available for processing operations. The server returns a "No such search object" error in response to requests made by client applications.
referral means a referral is returned for requests made to this suffix.
referral on update means the database is used for all operations except update requests, which receive a referral.

2.3.7. Replication Attributes under cn=replica, cn="suffixDN", cn=mapping tree, cn=config
Replication configuration attributes are stored under cn=replica, cn=suffix, cn=mapping tree, cn=config . The cn=replica entry is an instance of the nsDS5Replica object class. For replication configuration attributes to be taken into account by the server, this object class (in addition to the top object class) must be present in the entry. For further information about replication, see the
"Managing Replication" chapter in the Directory Server Administrator's Guide.
2.3.7.1. nsDS5Flags
This attribute sets replica properties that were previously defined in flags. At present only one flag exists, which sets whether the log changes.

Example
DirectoryString nsds5debugreplicatimeout: 60:8192
2.3.7.3. nsDS5ReplConflict
Although this attribute is not in the cn=replica entry, it is used in conjunction with replication.
This multi-valued attribute is included on entries that have a change conflict that cannot be resolved automatically by the synchronization process. To check for replication conflicts requiring administrator intervention, perform an LDAP search for (nsDS5ReplConflict=*). For example: ldapsearch -D cn=directory manager -w password -s sub -b dc=example,dc=com
"(|(objectclass=nsTombstone)(nsDS5ReplConflict=*))" dn nsDS5ReplConflict nsUniqueID
Using the search filter "(objectclass=nsTombstone)" also shows tombstone (deleted) entries.
The value of the nsDS5ReplConflict contains more information about which entries are in conflict, usually by referring to them by their nsUniqueID. It is possible to search for a tombstone entry by its nsUniqueID . For example: ldapsearch -D cn=directory manager -w password -s sub -b dc=example,dc=com "(|
(objectclass=nsTombstone)(nsUniqueID=66a2b699-1dd211b2-807fa9c3-a58714648))"

Example
DirectoryString nsDS5ReplicaAutoReferral: on
2.3.7.5. nsDS5ReplicaBindDN
This multi-valued attribute specifies the DN to use when binding. Although there can be more than one value in this cn=replica entry, there can only be one supplier bind DN per replication agreement.
80
Replication Attributes under cn=replica, cn="suffixDN", cn=mapping tree, cn=config
Each value should be the DN of a local entry on the consumer server. If replication suppliers are using client certificate-based authentication to connect to the consumers, configure the certificate mapping on the consumer to map the subjectDN in the certificate to a local entry.
Parameter

Description cn=replica, cn=suffixDN, cn=mapping tree, cn=config
Any valid DN Valid Values
Default Value
Syntax
Example
DirectoryString nsDS5ReplicaBindDN: cn=replication manager, cn=config
2.3.7.6. nsDS5ReplicaChangeCount
This read-only attribute shows the total number of entries in the changelog and whether they still remain to be replicated. When the changelog is purged, only the entries that are still to be replicated remain.
See
Section 2.3.7.10, “nsDS5ReplicaPurgeDelay” and
“nsDS5ReplicaTombstonePurgeInterval” for more information about purge operation properties.

Example
Description cn=replica, cn=suffixDN, cn=mapping tree, cn=config true | false false
DirectoryString nsDS5ReplicaLegacyConsumer: false
2.3.7.9. nsDS5ReplicaName
This attribute specifies the name of the replica with a unique identifier for internal operations. If it is not specified, this unique identifier is allocated by the server when the replica is created.
NOTE
It is recommended that the server be permitted to generate this name. However, in certain circumstances, for example, in replica role changes (master to hub etc.), this value needs to be specified. Otherwise, the server will not use the correct changelog database, and replication fails.
This attribute is destined for internal use only.
Parameter
Entry DN
Valid Values
Default Value
Syntax
Example
Description cn=replica, cn=suffixDN, cn=mapping tree, cn=config
DirectoryString (a UID identifies the replica) nsDS5ReplicaName:
66a2b699-1dd211b2-807fa9c3-a58714648
2.3.7.10. nsDS5ReplicaPurgeDelay
This attribute controls the maximum age of deleted entries (tombstone entries) and state information.
The Directory Server stores tombstone entries and state information so that when a conflict occurs in a multi-master replication process, the server resolves the conflicts based on the timestamp and replica
ID stored in the change sequence numbers.
An internal Directory Server housekeeping operation periodically removes tombstone entries which are older than the value of this attribute (in seconds). State information which is older than the nsDS5ReplicaPurgeDelay value is removed when an entry which contains the the state information is modified.
Not every tombstone and state information may be removed because, with multi-master replication, the server may need to keep a small number of the latest updates to prime replication, even if they are older than the value of the attribute.
82
Replication Attributes under cn=replica, cn="suffixDN", cn=mapping tree, cn=config
This attribute specifies the interval, in seconds, to perform internal purge operations on an entry. When setting this attribute, ensure that the purge delay is longer than the longest replication cycle in the replication policy to preserve enough information to resolve replication conflicts and to prevent the copies of data stored in different servers from diverging.
Parameter
Entry DN
Valid Range
Default Value
Syntax
Example
Description cn=replica, cn=suffixDN, cn=mapping tree, cn=config
0 (keep forever) to maximum 32-bit integer

This is used internally by the Directory Server supplier.
2.3.7.17. nsState
This attribute stores information on the state of the clock. It is designed only for internal use to ensure that the server cannot generate a change sequence number (csn) inferior to existing ones required for detecting backward clock errors.
2.3.8. Replication Attributes under cn=ReplicationAgreementName, cn=replica, cn="suffixName", cn=mapping tree, cn=config
The replication attributes that concern the replication agreement are stored under cn= ReplicationAgreementName, cn=replica, cn=suffixDN, cn=mapping tree, cn=config.
The cn=ReplicationAgreementName entry is an instance of the nsDS5ReplicationAgreement object class. Replication agreements are configured only on supplier replicas.
2.3.8.1. cn
This attribute is used for naming. Once this attribute has been set, it cannot be modified. This attribute is required for setting up a replication agreement.
Parameter

2.3.8.5. nsDS5ReplicaBusyWaitTime
This attribute sets the amount of time in seconds a supplier should wait after a consumer sends back a busy response before making another attempt to acquire access. The default value is three (3) seconds. If the attribute is set to a negative value, Directory Server sends the client a message and an
LDAP_UNWILLING_TO_PERFORM error code.
The nsDS5ReplicaBusyWaitTime attribute works in conjunction with the nsDS5ReplicaSessionPauseTime attribute. The two attributes are designed so that the nsDS5ReplicaSessionPauseTime interval is always at least one second longer than the interval specified for nsDS5ReplicaBusyWaitTime. The longer interval gives waiting suppliers a better chance to gain consumer access before the previous supplier can re-access the consumer.
Set the nsDS5ReplicaBusyWaitTime attribute at any time by using changetype:modify with the replace operation. The change takes effect for the next update session if one is already in progress.

2.3.8.19. nsDS5ReplicaSessionPauseTime
This attribute sets the amount of time in seconds a supplier should wait between update sessions.
The default value is 0. If the attribute is set to a negative value, Directory Server sends the client a message and an LDAP_UNWILLING_TO_PERFORM error code.
The nsDS5ReplicaSessionPauseTime attribute works in conjunction with the nsDS5ReplicaBusyWaitTime attribute. The two attributes are designed so that the nsDS5ReplicaSessionPauseTime interval is always at least one second longer than the interval specified for nsDS5ReplicaBusyWaitTime. The longer interval gives waiting suppliers a better chance to gain consumer access before the previous supplier can re-access the consumer.
• If either attribute is specified but not both, nsDS5ReplicaSessionPauseTime is set automatically to 1 second more than nsDS5ReplicaBusyWaitTime.
• If both attributes are specified, but nsDS5ReplicaSessionPauseTime is less than or equal to nsDS5ReplicaBusyWaitTime , nsDS5ReplicaSessionPauseTime is set automatically to 1 second more than nsDS5ReplicaBusyWaitTime.
91
Chapter 2. Core Server Configuration Reference
When setting the values, ensure that the nsDS5ReplicaSessionPauseTime interval is at least 1 second longer than the interval specified for nsDS5ReplicaBusyWaitTime. Increase the interval as needed until there is an acceptable distribution of consumer access among the suppliers.
Set the nsDS5ReplicaSessionPauseTime attribute at any time by using changetype:modify with the replace operation. The change takes effect for the next update session if one is already in progress.
If Directory Server has to reset the value of nsDS5ReplicaSessionPauseTime automatically, the value is changed internally only. The change is not visible to clients, and it is not saved to the configuration file. From an external viewpoint, the attribute value appears as originally set.

2.3.8.20. nsDS5ReplicatedAttributeList
This allowed attribute specifies any attributes that are not replicated to a consumer server. Fractional replication allows databases to be replicated across slow connections or to less secure consumers while still protecting sensitive information. By default, all attributes are replicated, and this attribute is not present. For more information on fractional replication, see the "Managing Replication" chapter in the Directory Server Administrator's Guide.
Parameter
Entry DN
Description cn=ReplicationAgreementName, cn=replica, cn=suffixDN, cn=mapping tree, cn=config

2.3.8.21. nsDS5ReplicaTimeout
This allowed attribute specifies the number of seconds outbound LDAP operations waits for a response from the remote replica before timing out and failing. If the server writes Warning: timed out waiting messages in the error log file, then increase the value of this attribute.
Find out the amount of time the operation actually lasted by examining the access log on the remote machine, and then set the nsDS5ReplicaTimeout attribute accordingly to optimize performance.
Parameter

2.3.8.24. nsDS5ReplicaUpdateSchedule
This multi-valued attribute specifies the replication schedule and can be modified. Changes made to this attribute take effect immediately. Modifying this value can be useful to pause replication and resume it later. For example, if this value to 0000-0001 0, this in effect causes the server to stop sending updates for this replication agreement. The server continues to store them for replay later. If the value is later changed back to 0000-2359 0123456, this makes replication immediately resume and sends all pending changes.

2.3.9. Synchronization Attributes under cn=syncAgreementName, cn=WindowsReplica,cn="suffixName", cn=mapping tree, cn=config
The synchronization attributes that concern the synchronization agreement are stored under cn=syncAgreementName, cn=WindowsReplica, cn=suffixDN, cn=mapping tree, cn=config . The cn=syncAgreementName entry is an instance of the nsDSWindowsReplicationAgreement object class. For synchronization agreement configuration attributes to be taken into account by the server, this object class (in addition to the top object class) must be present in the entry. Synchronization agreements are configured only on databases that are enabled to synchronize with Windows Active Directory servers.

2.3.10. cn=monitor
Information used to monitor the server is stored under cn=monitor. This entry and its children are read-only; clients cannot directly modify them. The server updates this information automatically. This section describes the cn=monitor attributes. The only attribute that can be changed by a user to set access control is the aci attribute.
If the nsslapd-counters attribute in cn=config is set to on (the default setting), then all of the counters kept by the Directory Server instance increment using 64-bit integers, even on 32-bit machines or with a 32-bit version of Directory Server. For the cn=monitor entry, the 64-bit integers are used with the opsinitiated, opscompleted, entriessent, and bytessent counters.
NOTE
The nsslapd-counters attribute enables 64-bit support for these specific database and server counters. The counters which use 64-bit integers are not configurable; the 64-bit integers are either enabled for all the allowed counters or disabled for all allowed counters.
connection
This attribute lists open connections. These are given in the following format: connection: A:YYYYMMDDhhmmssZ:B:C:D:E
For example: connection: 31:20010201164808Z:45:45::cn=directory manager
• A is the connection number, which is the number of the slot in the connection table associated with this connection. This is the number logged as slot=A in the access log message when this connection was opened, and usually corresponds to the file descriptor associated with the connection. The attribute dTableSize shows the total size of the connection table.
• YYYYMMDDhhmmssZ is the date and time, in GeneralizedTime form, at which the connection was opened. This value gives the time in relation to Greenwich Mean Time.
• B is the number of operations received on this connection.
• C is the number of completed operations.
• D is r if the server is in the process of reading BER from the network, empty otherwise. This value is usually empty (as in the example).

2.3.14. SNMP Statistic Attributes
for LDAP and SNMP clients. Unless otherwise noted, the value for the given attribute is the number of requests received by the server or results returned by the server since startup. Some of these attributes are not used by or are not applicable to the Directory Server but are still required to be present by SNMP clients.
If the nsslapd-counters attribute in cn=config is set to on (the default setting), then all of the counters kept by the Directory Server instance increment using 64-bit integers, even on 32-bit machines or with a 32-bit version of Directory Server. All of the SNMP statistics attributes use the 64bit integers, if it is configured.
NOTE
The nsslapd-counters attribute enables 64-bit integers for these specific database and server counters. The counters which use 64-bit integers are not configurable; 64-bit integers are either enabled for all the allowed counters or disabled for all allowed counters.

2.3.15. cn=tasks
Some core Directory Server tasks can be initiated by editing a directory entry using LDAP tools. These task entries are contained in cn=tasks. Each task can be invoked by updating an entry such as the following: dn: cn=task_id, cn=task_type, cn=tasks, cn=config
...
In Red Hat Directory Server deployments before Directory Server 8.0, many Directory Server tasks were managed by the Administration Server. These tasks were moved to the core Directory
Server configuration in version 8.0 and are invoked and administered by Directory Server under the cn=tasks entry.
There are seven tasks that are managed under the cn=tasks entry:
•
•
•
•
•
•
•
104
cn=tasks
The common attributes for these tasks are listed in
Section 2.3.15.1, “Task Invocation Attributes for
The cn=tasks entry itself has no attributes and serves as the parent and container entry for the individual task entries.
IMPORTANT
Task entries are not permanent configuration entries. They only exist in the configuration file for as long as the task operation is running or until the ttl period expires. Then, the entry is deleted automatically by the server.
2.3.15.1. Task Invocation Attributes for Entries under cn=tasks
Five tasks which administer Directory Server instances have configuration entries which initiate and identify individual operations. These task entries are instances of the same object class, extensibleObject , and have certain common attributes which describe the state and behavior of
Directory Server tasks. The task types can be import, export, backup, restore, index, schema reload, and memberof.
cn
The cn attribute is used to identify a new task operation to initiate. The cn attribute value can be anything, as long as it defines a new task.
Parameter
Entry DN
Description cn=task_name, cn=task_type, cn=tasks, cn=config
Any string Valid Values
Default Value
Syntax
Example
DirectoryString cn: example task entry name nsTaskStatus
This attribute contains changing information about the status of the task, such as cumulative statistics or its current output message. The entire contents of the attribute may be updated periodically for as long as the process is running.

Chapter 2. Core Server Configuration Reference
Parameter
Example
Description nsTaskStatus: Loading entries....
nsTaskLog
This entry contains all of the log messages for the task, including both warning and information messages. New messages are appended to the end of the entry value, so this attribute value grows larger, without erasing the original contents, by default.
Successful task operations, which have an nsTaskExitCode of 0, are only recorded in the nsTaskLog attribute. Any non-zero response, which indicates an error, may be recorded in the error log as an error, but the error message is only recorded in the nsTaskLog attribute. For this reason, use the information in the nsTaskLog attribute to find out what errors actually occurred.
This attribute value is set by the server and should not be edited.
Parameter
Entry DN
Description cn=task_name, cn=task_type, cn=tasks, cn=config
Any string Valid Values
Default Value
Syntax
Example
Case-exact string nsTaskLog: example...
nsTaskExitCode
This attribute contains the exit code for the task. This attribute only exists after the task is completed and any value is only valid if the task is complete. The result code can be any LDAP exit code, as listed in
Section 5.4, “LDAP Result Codes”
, but only a 0 value equals success; any other result code is an error.
This attribute value is set by the server and should not be edited.
Parameter

Syntax
Example
1
Any response other than 0 is an error.
Integer nsTaskExitCode: 0 nsTaskCurrentItem
This attribute shows the number of subtask which the task operation has completed, assuming the task can be broken down into subtasks. If there is only one task, then nsTaskCurrentItem is 0 while the task is running, and 1 when the task is complete. In this way, the attribute is analogous to a
106
cn=tasks progress bar. When the nsTaskCurrentItem attribute has the same value as nsTaskTotalItems, then the task is completed.
This attribute value is set by the server and should not be edited.

2.3.15.2. cn=import
An LDIF file or multiple LDIF files can be imported through the command line by creating a special task entry which defines the parameters of the task and initiates the task. As soon as the task is complete, the task entry is removed from the directory.
The cn=import entry is a container entry for import task operations. The cn=import entry itself has no attributes, but each of the task entries within this entry, such as cn=task_ID, cn=import, cn=tasks , cn=config, uses the following attributes to define the import task.
An import task entry under cn=import must contain the LDIF file to import (in the nsFilename
attribute) and the name of the instance into which to import the file (in the
attribute).
Additionally, it must contain a unique cn to identify the task. For example: dn: cn=example import, cn=import, cn=tasks, cn=config objectclass: extensibleObject cn: example import nsFilename: /home/files/example.ldif
nsInstance: userRoot
As the import operation runs, the task entry will contain all of the server-generated task attributes listed in
Section 2.3.15.1, “Task Invocation Attributes for Entries under cn=tasks” .
There are some optional attributes which can be used to refine the import operation, similar to the options for the ldif2db and ldif2db.pl scripts:
•
, which is analogous to the -s option to specify the suffix to import
•
, analogous to the -x option to specify a suffix or subtree to exclude from the import
•
nsImportChunkSize , analogous to the -c option to override starting a new pass during the import
and merge the chunks
•
nsImportIndexAttrs , which sets whether to import attribute indexes (with no corollary in the script
options)
•
, analogous to the -g option to generate unique ID numbers for the entries
•
, analogous to the -G option to generate a unique, name-based ID for the entries
108
cn=tasks nsFilename

2.3.15.3. cn=export
A database or multiple databases can be exported through the command line by creating a special task entry which defines the parameters of the task and initiates the task. As soon as the task is complete, the task entry is removed from the directory.
The cn=export entry is a container entry for export task operations. The cn=export entry itself has no attributes, but each of the task entries within this entry, such as cn=task_ID, cn=export, cn=tasks , cn=config, uses the following attributes to define the export task.
An export task entry under cn=export must contain the name of the database to export (in the
attribute) and the name of the LDIF file to write the output to (in the
attribute).
Additionally, it must contain a unique cn to identify the task. For example: dn: cn=example export, cn=export, cn=tasks, cn=config objectclass: extensibleObject cn: example export nsInstance: userRoot nsFilename: /home/files/example.ldif
As the export operation runs, the task entry will contain all of the server-generated task attributes listed in
Section 2.3.15.1, “Task Invocation Attributes for Entries under cn=tasks”
.
There are some optional attributes which can be used to refine the export operation, similar to the options for the db2ldif and db2ldif.pl scripts:
•
, analogous to the -s option, to specify the suffixes to include in the exported LDIF files
•
, analogous to the -x option, to exclude the specified suffixes from the exported
LDIF files
•
nsUseOneFile , analogous to the -M option, to break up the exported suffixes into individual LDIF
files
•
nsExportReplica , analogous to the -r option, to indicate whether the exported database is used in
replication
•
, analogous to the -N option, to set whether to print the entry IDs as the entries are processed by the export operation
111
Chapter 2. Core Server Configuration Reference
•
, analogous to the -C option, to set whether to use only the main index, id2entry, to list the entries to export
•
nsNoWrap , analogous to the -U option, to set whether to wrap long lines in the LDIF file

2.3.15.7. cn=schema reload task
The directory schema is loaded when the directory instance is started or restarted. Any changes to the directory schema, including adding custom schema elements, are not loaded automatically and available to the instance until the server is restarted or by initiating a schema reload task.
Custom schema changes can be reloaded dynamically, without having to restart the Directory Server instance. This is done by initiating a schema reload task through creating a new task entry under the cn=tasks entry.
The custom schema file can be located in any directory; if not specified with the
the server reloads the schema from the default /etc/dirsrv/slapd-instance_name/schema directory.
IMPORTANT
Any schema loaded from another directory must be copied into the schema directory or the schema will be lost when the server.
The schema reload task is initiated though the command line by creating a special task entry which defines the parameters of the task and initiates the task. As soon as the task is complete, the task entry is removed from the directory. For example: dn: cn=example schema reload,cn=schema reload task, cn=tasks, cn=config objectclass: extensibleObject cn:example schema reload schemadir: /export/schema
The cn=schema reload task entry is a container entry for schema reload operations. The cn=schema reload task entry itself has no attributes, but each of the task entries within this entry, such as cn=task_ID, cn=schema reload task, cn=tasks, cn=config, uses the schema reload attributes to define the individual reload task.
cn
The cn attribute is used to identify a new task operation to initiate. The cn attribute value can be anything, as long as it defines a new task.

2.3.15.8. cn=memberof task
The memberOf attribute is created and managed by the Directory Server automatically to display group membership on the members' user entries. When the member attribute on a group entry is changed, all of the members' associated directory entries are automatically updated with their corresponding memberOf attributes.
The cn=memberof task (and the related fixup-memberof.pl script) is used to create the initial memberOf attributes on the member's user entries in the directory. After the memberOf attributes are created, then the MemberOf Plug-in manages the memberOf attributes automatically.
The memberOf update task must give the DN of the entry or subtree to run the update task against
(set in the
basedn attribute). Optionally, the task can include a filter to identify the members' user
entries to update (set in the
filter attribute). For example:
dn: cn=example memberof, cn=memberof task, cn=tasks, cn=config objectclass: extensibleObject cn:example memberof basedn: ou=people,dc=example,dc=com filter: (objectclass=groupOfNames)
As soon as the task is complete, the task entry is removed from the directory.
The cn=memberof task entry is a container entry for memberOf update operations. The cn=memberof task entry itself has no attributes, but each of the task entries beneath this entry, such as cn=task_ID, cn=memberof task, cn=tasks, cn=config, uses its attributes to define the individual update task.

Plug-in Implemented Server
Functionality Reference
This chapter contains reference information on Red Hat Directory Server plug-ins.
The configuration for each part of Directory Server plug-in functionality has its own separate entry and set of attributes under the subtree cn=plugins, cn=config.
dn: cn=Telephone Syntax, cn=plugins, cn=config objectclass: top objectclass: nsSlapdPlugin objectclass: extensibleObject cn: Telephone Syntax nsslapd-pluginPath: libsyntax-plugin nsslapd-pluginInitfunc: tel_init nsslapd-pluginType: syntax nsslapd-pluginEnabled: on
Some of these attributes are common to all plug-ins while others may be particular to a specific plugin. Check which attributes are currently being used by a given plug-in by performing an ldapsearch on the cn=config subtree.
All plug-ins are instances of the nsSlapdPlugin object class, which in turn inherits from the extensibleObject object class. For plug-in configuration attributes to be taken into account by the server, both of these object classes (in addition to the top object class) must be present in the entry, as shown in the following example: dn:cn=ACL Plugin, cn=plugins, cn=config objectclass:top objectclass:nsSlapdPlugin objectclass:extensibleObject
3.1. Server Plug-in Functionality Reference
The following tables provide a quick overview of the plug-ins provided with Directory Server, along with their configurable options, configurable arguments, default setting, dependencies, general performance-related information, and further reading. These tables assist in weighing plug-in performance gains and costs and choose the optimal settings for the deployment. The Further
Information section cross-references further reading, where this is available.

on | off off
To check for UID attribute uniqueness in all listed subtrees, enter uid "DN"
"DN"...
. However, to check for UID attribute uniqueness when adding or updating entries with the requiredObjectClass, enter attribute="uid" MarkerObjectclass
= "ObjectClassName" and, optionally requiredObjectClass =
"ObjectClassName" . This starts checking for the required object classes from the parent entry containing the ObjectClass as defined by the
MarkerObjectclass attribute.
Database
Directory Server provides the UID Uniqueness
Plug-in by default. To ensure unique values for other attributes, create instances of the Attribute
Uniqueness Plug-in for those attributes. See the
"Using the Attribute Uniqueness Plug-in" in the
Directory Server Administrator's Guide for more information about the Attribute Uniqueness Plugin.
The UID Uniqueness Plug-in is off by default due to operation restrictions that need to be addressed before enabling the plug-in in a multimaster replication environment. Turning the plug-in on may slow down Directory Server performance.
See the"Using the Attribute Uniqueness Plug-in" in the Directory Server Administrator's Guide.

3.1.25. Password Storage Schemes
The cn=Password Storage Schemes entry is a container entry, not a plug-in entry itself. All of the plug-ins used for encryption are stored under this entry. The supported schemes change as new encryption methods are added; to view the complete and current list, list the entries under cn=Password Storage Schemes, cn=plugins, cn=config:
/usr/lib/mozldap/ldapsearch -D "cn=directory manager" -w secret12 -p 389 -b "cn=Password
Storage Schemes,cn=plugins, cn=config" -s sub (objectclass=*)
The different password storage scheme plug-ins are stored in entries named in the format: cn=Storage Scheme Name Plugin,cn=Password Storage Schemes,cn=plugins,cn=config
For more information on using the different password storage schemes, see the "User Account
Management" chapter in the Directory Server Administrator's Guide.

The Referential Integrity Plug-in should be enabled only on one master in a multimaster replication environment to avoid conflict resolution loops. When enabling the plug-in on chained servers, be sure to analyze the performance resource and time needs as well as integrity needs; integrity checks can be time consuming and demanding on memory and
CPU. All attributes specified must be indexed for both presence and equality.

Chapter 3. Plug-in Implemented Server Functionality Reference
3.4.1.1. nsLookThroughLimit
This performance-related attribute specifies the maximum number of entries that the Directory Server will check when examining candidate entries in response to a search request. The Directory Manager
DN, however, is, by default, unlimited and overrides any other settings specified here. It is worth noting that binder-based resource limits work for this limit, which means that if a value for the operational attribute nsLookThroughLimit is present in the entry as which a user binds, the default limit will be overridden. Attempting to set a value that is not a number or is too big for a 32-bit signed integer returns an LDAP_UNWILLING_TO_PERFORM error message with additional error information explaining the problem.
Parameter
Entry DN
Valid Range
Default Value
Syntax
Example
Description cn=config, cn=ldbm database, cn=plugins, cn=config
-1 to maximum 32-bit integer in entries (where -1 is unlimited)
5000
Integer nsLookThroughLimit: 5000
3.4.1.2. nsslapd-idlistscanlimit
This performance-related attribute, present by default, specifies the number of entry IDs that are searched during a search operation. Attempting to set a value that is not a number or is too big for a
32-bit signed integer returns an LDAP_UNWILLING_TO_PERFORM error message, with additional error information explaining the problem.
It is advisable to keep the default value to improve search performance. For a more detailed explanation of the effect of ID lists on search performance, refer to the "Managing Indexes" chapter in the Directory Server Administrator's Guide.
The server has to be restarted for changes to this attribute to go into effect.

Integer nsslapd-idlistscanlimit: 4000
3.4.1.3. nsslapd-cache-autosize
This performance tuning-related attribute, which is turned off by default, specifies the percentage of free memory to use for all the combined caches. For example, if the value is set to 80, then 80 percent of the remaining free memory would be claimed for the cache. To run other servers on the machine, then set the value lower. Setting the value to 0 turns off the cache autosizing and uses the normal nsslapd-cachememsize and nsslapd-dbcachesize attributes.

NOTE
If the nsslapd-cache-autosize attribute and nsslapd-cache-autosize- split attribute are both set to high values, such as 100, then the Directory Server may fail to start and return an error message. To fix this issue, reset the nsslapd- cache-autosize and nsslapd-cache-autosize-split attributes to a more reasonable level. For example: nsslapd-cache-autosize: 60 nsslapd-cache-autosize-split: 60

Integer nsslapd-cache-autosize: 80
3.4.1.4. nsslapd-cache-autosize-split
This performance tuning-related attribute specifies the percentage of cache space to allocate to the database cache. For example, setting this to 60 would give the database cache 60 percent of the cache space and split the remaining 40 percent between the backend entry caches. That is, if there were two databases, each of them would receive 20 percent. This attribute only applies when the nsslapd-cache-autosize attribute has a value of 0.
NOTE
If the nsslapd-cache-autosize attribute and nsslapd-cache-autosize- split attribute are both set to high values, such as 100, then the Directory Server may fail to start and return error message. To fix this issue, reset the nsslapd- cache-autosize and nsslapd-cache-autosize-split attributes to a more reasonable level. For example: nsslapd-cache-autosize: 60 nsslapd-cache-autosize-split: 60
Description cn=config, cn=ldbm database, cn=plugins, cn=config

Chapter 3. Plug-in Implemented Server Functionality Reference
3.4.1.5. nsslapd-dbcachesize
This performance tuning-related attribute specifies the database index cache size, in bytes. This is one of the most important values for controlling how much physical RAM the directory server uses.
This is not the entry cache. This is the amount of memory the Berkeley database backend will use to cache the indexes (the .db4 files) and other files. This value is passed to the Berkeley DB API function set_cachesize. If automatic cache resizing is activated, this attribute is overridden when the server replaces these values with its own guessed values at a later stage of the server startup.
For more technical information on this attribute, see the cache size section of the Berkeley DB reference guide at http://www.oracle.com/technology/documentation/berkeley-db/db/api_c/ env_set_cachesize.html
.
Attempting to set a value that is not a number or is too big for a 32-bit signed integer returns an
LDAP_UNWILLING_TO_PERFORM error message with additional error information explaining the problem.
The server has to be restarted for changes to this attribute to go into effect.

3.4.1.6. nsslapd-db-checkpoint-interval
This sets the amount of time in seconds after which the Directory Server sends a checkpoint entry to the database transaction log. The database transaction log contains a sequential listing of all recent database operations and is used for database recovery only. A checkpoint entry indicates which database operations have been physically written to the directory database. The checkpoint entries are used to determine where in the database transaction log to begin recovery after a system failure.
The nsslapd-db-checkpoint-interval attribute is absent from dse.ldif. To change the checkpoint interval, add the attribute to dse.ldif. This attribute can be dynamically modified using ldapmodify . For further information on modifying this attribute, see the "Tuning Directory Server
Performance" chapter in the Directory Server Administrator's Guide.
This attribute is provided only for system modification/diagnostics and should be changed only with the guidance of Red Hat technical support or Red Hat professional services. Inconsistent settings of this attribute and other configuration attributes may cause the Directory Server to be unstable.

3.4.1.7. nsslapd-db-circular-logging
This attribute specifies circular logging for the transaction log files. If this attribute is switched off, old transaction log files are not removed and are kept renamed as old log transaction files. Turning circular logging off can severely degrade server performance and, as such, should only be modified with the guidance of Red Hat Technical Support or Red Hat Professional Services.

3.4.1.9. nsslapd-db-durable-transactions
This attribute sets whether database transaction log entries are immediately written to the disk. The database transaction log contains a sequential listing of all recent database operations and is used for database recovery only. With durable transactions enabled, every directory change will always be physically recorded in the log file and, therefore, able to be recovered in the event of a system failure. However, the durable transactions feature may also slow the performance of the Directory
Server. When durable transactions is disabled, all transactions are logically written to the database transaction log but may not be physically written to disk immediately. If there were a system failure before a directory change was physically written to disk, that change would not be recoverable. The nsslapd-db-durable-transactions attribute is absent from dse.ldif. To disable durable transactions, add the attribute to dse.ldif.

3.4.1.10. nsslapd-db-home-directory
This is usually applicable to Solaris only, and is used to fix a situation in Solaris where the operating system endlessly flushes pages. This flushing can be so excessive that performance of the entire system is severely degraded.
For users of other systems, to move the database to another physical location for performance reasons, use this parameter to specify the home directory.
This situation will occur only for certain combinations of the database cache size, the size of physical memory, and kernel tuning attributes. In particular, this situation should not occur if the database cache size is less than 100 megabytes.
If the Solaris host seems excessively slow and the database cache size is around 100 megabytes or more, then use the iostat utility to diagnose the problem by monitoring the activity of the disk where the Directory Server's database files are stored. There are three conditions required before resetting the nsslapd-db-home-directory attribute:
• The disk is heavily used (more than 1 megabyte per second of data transfer).
• There is a long service time (more than 100ms).
• There is mostly write activity.
If these are all true, use the nsslapd-db-home-directory attribute to specify a subdirectory of a tempfs type filesystem.
The directory referenced by the nsslapd-db-home-directory attribute must be a subdirectory of a filesystem of type tempfs (such as /tmp). However, Directory Server does not create the subdirectory referenced by this attribute. This directory must be created either manually or by using a script. Failure to create the directory referenced by the nsslapd-db-home-directory attribute will result in Directory Server being unable to start.
Also, if there are multiple Directory Servers on the same machine, their nsslapd-db-home- directory attributes must be configured with different directories. Failure to do so will result in the databases for both directories becoming corrupted.
170
Database Attributes under cn=config, cn=ldbm database, cn=plugins, cn=config
The use of this attribute causes internal Directory Server database files to be moved to the directory referenced by the attribute. It is possible, but unlikely, that the server will no longer start after the files have been moved because not enough memory can be allocated. This is a symptom of an overly large database cache size being configured for the server. If this happens, reduce the size of the database cache size to a value where the server will start again.
Parameter
Entry DN
Valid Values
Description cn=config, cn=ldbm database, cn=plugins, cn=config

DirectoryString nsslapd-db-home-directory: /tmp/slapdphonebook
3.4.1.11. nsslapd-db-idl-divisor
This attribute specifies the index block size in terms of the number of blocks per database page.
The block size is calculated by dividing the database page size by the value of this attribute. A value of 1 makes the block size exactly equal to the page size. The default value of 0 sets the block size to the page size minus an estimated allowance for internal database overhead. For the majority of installations, the default value should not be changed unless there are specific tuning needs.
Before modifying the value of this attribute, export all databases using the db2ldif script. Once the modification has been made, reload the databases using the ldif2db script.
WARNING
This parameter should only be used by very advanced users.

3.4.1.12. nsslapd-db-logbuf-size
This attribute specifies the log information buffer size. Log information is stored in memory until the buffer fills up or the transaction commit forces the buffer to be written to disk. Larger buffer sizes can significantly increase throughput in the presence of long running transactions, highly concurrent applications, or transactions producing large amounts of data. The log information buffer size is the transaction log size divided by four.

3.4.1.13. nsslapd-db-logdirectory
This attribute specifies the path and directory name of the directory containing the database transaction log. The database transaction log contains a sequential listing of all recent database operations and is used for database recovery only. By default, the database transaction log is stored in the same directory as the directory entries themselves, /var/lib/dirsrv/ slapd-instance_name/db . For fault-tolerance and performance reasons, move this log file to another physical disk. The nsslapd-db-logdirectory attribute is absent from dse.ldif. To change the location of the database transaction log, add the attribute to dse.ldif.
For more information on database transaction logging, refer to the "Monitoring Server and Database

3.4.1.15. nsslapd-db-page-size
This attribute specifies the size of the pages used to hold items in the database in bytes. The minimum size is 512 bytes, and the maximum size is 64 kilobytes. If the page size is not explicitly set, Directory
Server defaults to a page size of 8 kilobytes. Changing this default value can have a significant performance impact. If the page size is too small, it results in extensive page splitting and copying, whereas if the page size is too large it can waste disk space.

3.4.1.17. nsslapd-db-transaction-batch-val
This attribute specifies how many transactions will be batched before being committed. This attribute can improve update performance when full transaction durability is not required. This attribute can be dynamically modified using ldapmodify. For further information on modifying this attribute, refer to the "Tuning Directory Server Performance" chapter in the Directory Server Administrator's Guide.
173
Chapter 3. Plug-in Implemented Server Functionality Reference
WARNING
Setting this value will reduce data consistency and may lead to loss of data. This is because if there is a power outage before the server can flush the batched transactions, those transactions in the batch will be lost.
Do not set this value unless specifically requested to do so by Red Hat support.
If this attribute is not defined or is set to a value of 0, transaction batching will be turned off, and it will be impossible to make remote modifications to this attribute via LDAP. However, setting this attribute to a value greater than 0 causes the server to delay committing transactions until the number of queued transactions is equal to the attribute value. A value greater than 0 also allows modifications to this attribute remotely via LDAP. A value of 1 for this attribute allows modifications to the attribute setting remotely via LDAP, but results in no batching behavior. A value of 1 at server startup is therefore useful for maintaining normal durability while also allowing transaction batching to be turned on and off remotely when desired. Remember that the value for this attribute may require modifying the nsslapd-db-logbuf-size attribute to ensure sufficient log buffer size for accommodating the batched transactions.
NOTE
The nsslapd-db-transaction-batch-val attribute is only valid if the nsslapd-db-durable-transaction attribute is set to on.

3.4.1.20. nsslapd-dbncache
This attribute can split the LDBM cache into equally sized separate pieces of memory. It is possible to specify caches that are large enough so that they cannot be allocated contiguously on some architectures; for example, some systems limit the amount of memory that may be allocated contiguously by a process. If nsslapd-dbncache is 0 or 1, the cache will be allocated contiguously in memory. If it is greater than 1, the cache will be broken up into ncache, equally sized separate pieces of memory.
To configure a dbcache size larger than 4 gigabytes, add the nsslapd-dbncache attribute to cn=config, cn=ldbm database, cn=plugins, cn=config between the nsslapd- dbcachesize and nsslapd-db-logdirectory attribute lines.
Set this value to an integer that is one-quarter (1/4) the amount of memory in gigabytes. For example, for a 12 gigabyte system, set the nsslapd-dbncache value to 3; for an 8 gigabyte system, set it to 2.
This attribute is provided only for system modification/diagnostics and should be changed only with the guidance of Red Hat technical support or Red Hat professional services. Inconsistent settings of this attribute and other configuration attributes may cause the Directory Server to be unstable.
The server has to be restarted for changes to this attribute to go into effect.

3.4.1.22. nsslapd-import-cachesize
This performance tuning-related attribute determines the size, in bytes, of the database cache used in the bulk import process. Setting this attribute value so that the maximum available system physical memory is used for the database cache during bulk importing optimizes bulk import speed.
Attempting to set a value that is not a number or is too big for a 32-bit signed integer returns an
LDAP_UNWILLING_TO_PERFORM error message, with additional error information explaining the problem.
NOTE
A cache is created for each load that occurs. For example, if the user sets the nsslapd-import-cachesize attribute to 1 gigabyte, then 1 gigabyte is used when loading one database, 2 gigabytes is used when loading two databases, and so on.
Ensure there is sufficient physical memory to prevent swapping from occurring, as this would result in performance degradation.
Parameter

3.4.1.23. nsslapd-import-cache-autosize
This performance tuning-related attribute automatically sets the size of the import cache
(importCache) to be used during the command-line-based import process of LDIF files to the database (the ldif2db operation).
176
Database Attributes under cn=config, cn=ldbm database, cn=plugins, cn=config
In Directory Server, the import operation can be run as a server task or exclusively on the commandline. In the task mode, the import operation runs as a general Directory Server operation. The nsslapd-import-cache-autosize attribute enables the import cache to be set automatically to a predetermined size when the import operation is run on the command-line. The attribute can also be used by Directory Server during the task mode import for allocating a specified percentage of free memory for import cache.
By default, the nsslapd-import-cache-autosize attribute is enabled and is set to a value of -1.
This value autosizes the import cache for the ldif2db operation only, automatically allocating fifty percent (50%) of the free physical memory for the import cache. The percentage value (50%) is hardcoded and cannot be changed.
Setting the attribute value to 50 (nsslapd-import-cache-autosize: 50) has the same effect on performance during an ldif2db operation. However, such a setting will have the same effect on performance when the import operation is run as a Directory Server task. The -1 value autosizes the import cache just for the ldif2db operation and not for any, including import, general Directory
Server tasks.
NOTE
The purpose of a -1 setting is to enable the ldif2db operation to benefit from free physical memory but, at the same time, not compete for valuable memory with the entry cache, which is used for general operations of the Directory Server.
Setting the nsslapd-import-cache-autosize attribute value to 0 turns off the import cache autosizing feature - that is, no autosizing occurs during either mode of the import operation. Instead,
Directory Server uses the nsslapd-import-cachesize attribute for import cache size, with a default value of 20000000.
There are three caches in the context of Directory Server: database cache, entry cache, and import cache. The import cache is only used during the import operation. The nsslapd-cache-autosize attribute, which is used for autosizing the entry cache and database cache, is used during the
Directory Server operations only and not during the ldif2db command-line operation; the attribute value is the percentage of free physical memory to be allocated for the entry cache and database cache.
If both the autosizing attributes, nsslapd-cache-autosize and nsslapd-import-cache- autosize , are enabled, ensure that their sum is less than 100.

3.4.3. Database Attributes under cn=NetscapeRoot, cn=ldbm database, cn=plugins, cn=config and cn=userRoot, cn=ldbm database, cn=plugins, cn=config
The cn=NetscapeRoot and cn=userRoot subtrees contain configuration data for, or the definition of, the databases containing the o=NetscapeRoot and o=userRoot suffixes. The cn=NetscapeRoot subtree contains the configuration data used by the Administration Server for authentication and all actions that cannot be performed through LDAP (such as start/stop), and the cn=userRoot subtree contains all the configuration data for the user-defined database.
The cn=userRoot subtree is called userRoot by default. However, this is not hard-coded and, given the fact that there are going to be multiple database instances, this name is changed and defined by the user as and when new databases are added. The cn=userRoot database referenced can be any user database.
The following attributes are common to both the cn=NetscapeRoot, cn=ldbm database, cn=plugins, cn=config and the user database, such as cn=userRoot or cn=database_name, cn=ldbm database, cn=plugins, cn=config subtrees.
3.4.3.1. nsslapd-cachesize
This attribute has been deprecated. To resize the entry cache, use nsslapd-cachememsize.
This performance tuning-related attribute specifies the cache size in terms of the number of entries it can hold. However, this attribute is deprecated in favor of the nsslapd-cachememsize attribute, which sets an absolute allocation of RAM for the entry cache size, as described in
Attempting to set a value that is not a number or is too big for a 32-bit signed integer (on 32-bit systems) returns an LDAP_UNWILLING_TO_PERFORM error message with additional error information explaining the problem.

3.4.3.2. nsslapd-cachememsize
This performance tuning-related attribute specifies the size, in bytes, for the available memory space for the entry cache. The simplest method is limiting cache size in terms of memory occupied.
Activating automatic cache resizing overrides this attribute, replacing these values with its own guessed values at a later stage of the server startup.
The BerkeleyDB documentation 9 offers a good explanation of what the entry cache is, along with management information like how to monitor the cache with db_stat -m.
NOTE
The nsslapd-cachememsize attribute also defines the import buffer size. The import buffer size is automatically configured to be 80% of whatever the nsslapd- cachememsize setting is. When importing databases with very large attributes, be sure to reset the nsslapd-cachememsize value to something high enough so that .80*cacheSize is enough to allow the import to proceed.
Attempting to set a value that is not a number or is too big for a 32-bit signed integer (on 32-bit systems) returns an LDAP_UNWILLING_TO_PERFORM error message with additional error information explaining the problem.

The database instance directory is named after the instance name and located in the global database directory, by default. After the database instance has been created, do not modify this path, because any changes risk preventing the server from accessing data.

3.4.5.5. nsMatchingRule
This optional, multi-valued attribute specifies the ordering matching rule name or OID used to match values and to generate index keys for the attribute. This is most commonly used to ensure that equality and range searches work correctly for languages other than English (7-bit ASCII).
This is also used to allow range searches to work correctly for integer syntax attributes that do not specify an ordering matching rule in their schema definition. uidNumber and gidNumber are two commonly used attributes that fall into this category.
For example, for a uidNumber that uses integer syntax, the rule attribute could be nsMatchingRule: integerOrderingMatch .
NOTE
Any change to this attribute will not take effect until the change is saved and the index is rebuilt using db2index, which is described in more detail in the "Managing

3.4.7. Database Attributes under cn=index, cn=NetscapeRoot, cn=ldbm database, cn=plugins, cn=config and cn=index, cn=UserRoot, cn=ldbm database, cn=plugins, cn=config
In addition to the set of default indexes that are stored under cn=default indexes, cn=config, cn=ldbm database, cn=plugins, cn=config , custom indexes can be created for o=NetscapeRoot , o=UserRoot, and user-defined backend instances; these are stored under cn= index, cn=database_name, cn=ldbm database, cn=plugins, cn=config. Each indexed attribute represents a subentry under the cn=config information tree nodes, as shown in the following diagram:
Figure 3.2. Indexed Attribute Representing a Subentry
For example, the index file for the aci attribute under o=UserRoot appears in the Directory Server as follows: dn:cn=aci, cn=index, cn=UserRoot, cn=ldbm database, cn=plugins, cn=config objectclass:top objectclass:nsIndex cn:aci nsSystemIndex:true nsIndexType:pres
These entries share all of the indexing attributes listed for the default indexes in
“Database Attributes under cn=default indexes, cn=config, cn=ldbm database, cn=plugins, cn=config” .
For further information about indexes, refer to the "Managing Indexes" chapter in the Directory Server
Administrator's Guide.
3.4.7.1. nsSubStrBegin
By default, for a search to be indexed, the search string must be at least three characters long, without counting any wildcard characters. For example, the string abc would be an indexed search while ab* would not be. Indexed searches are significantly faster than unindexed searches, so changing the minimum length of the search key is helpful to increase the number of indexed searches.
This substring length can be edited based on the position of any wildcard characters. The nsSubStrBegin attribute sets the required number of characters for an indexed search for the beginning of a search string, before the wildcard. For example: abc*

3.4.8. Database Attributes under cn=attributeName, cn=encrypted attributes, cn=database_name, cn=ldbm database, cn=plugins, cn=config
The nsAttributeEncryption object class allows selective encryption of attributes within a database. Extremely sensitive information such as credit card numbers and government identification numbers may not be protected enough by routine access control measures. Normally, these attribute values are stored in CLEAR within the database; encrypting them while they are stored adds another layer of protection. This object class has one attribute, nsEncryptionAlgorithm, which sets the encryption cipher used per attribute. Each encrypted attribute represents a subentry under the above cn=config information tree nodes, as shown in the following diagram:
Figure 3.3. Encrypted Attributes under the cn=config Node
For example, the database encryption file for the userPassword attribute under o=UserRoot appears in the Directory Server as follows: dn:cn=userPassword, cn=encrypted attributes,o=UserRoot, cn=ldbm database, cn=plugins, cn=config objectclass:top objectclass:nsAttributeEncryption cn:userPassword nsEncryptionAlgorithm:AES

This section covers global configuration attributes common to all instances are stored in the cn=config, cn=chaining database, cn=plugins, cn=config tree node.
3.5.1.1. nsActiveChainingComponents
This attribute lists the components using chaining. A component is any functional unit in the server.
The value of this attribute overrides the value in the global configuration attribute. To disable chaining on a particular database instance, use the value None. This attribute also allows the components used to chain to be altered. By default, no components are allowed to chain, which explains why this attribute will probably not appear in a list of cn=config, cn=chaining database, cn=config attributes, as LDAP considers empty attributes to be non-existent.

3.5.3. Database Link Attributes under cn=database_link_name, cn=chaining database, cn=plugins, cn=config
This information node stores the attributes concerning the server containing the data. A farm server is a server which contains data on databases. This attribute can contain optional servers for failover, separated by spaces. For cascading chaining, this URL can point to another database link.
3.5.3.1. nsBindMechanism
This attribute sets a bind mechanism for the farm server to connect to the remote server. A farm server is a server containing data in one or more databases. This attribute configures the connection type, either standard, SSL, or SASL.
• empty. This performs simple authentication and requires the nsMultiplexorBindDn and nsMultiplexorCredentials attributes to give the bind information.
• EXTERNAL. This uses an SSL certificate to authenticate the farm server to the remote server.
Either the farm server URL must be set to the secure URL (ldaps) or the nsUseStartTLS attribute must be set to on.
Additionally, the remote server must be configured to map the farm server's certificate to its bind identity. Certificate mapping is described in the Administrator's Guide.
• DIGEST-MD5. This uses SASL with DIGEST-MD5 encryption. As with simple authentication, this requires the nsMultiplexorBindDn and nsMultiplexorCredentials attributes to give the bind information.
• GSSAPI. This uses Kerberos-based authentication over SASL. The farm server must be connected over the standard port, meaning the URL has ldap, because the Directory Server does not support
SASL/GS-API over SSL.
The farm server must be configured with a Kerberos keytab, and the remote server must have a defined SASL mapping for the farm server's bind identity. Setting up Kerberos keytabs and SASL mappings is described in the Administrator's Guide.

3.6. Retro Changelog Plug-in Attributes
Two different types of changelogs are maintained by Directory Server. The first type, referred to as simply a changelog, is used by multi-master replication, and the second changelog, a plug-in referred to as the retro changelog, is intended for use by LDAP clients for maintaining application compatibility with Directory Server 4.x versions.
This Retro Changelog Plug-in is used to record modifications made to a supplier server. When the supplier server's directory is modified, an entry is written to the Retro Changelog that contains both of the following:
• A number that uniquely identifies the modification. This number is sequential with respect to other entries in the changelog.
205
Chapter 3. Plug-in Implemented Server Functionality Reference
• The modification action; that is, exactly how the directory was modified.
It is through the Retro Changelog Plug-in that the changes performed to the Directory Server are accessed using searches to cn=changelog suffix.
3.6.1. nsslapd-changelogdir
This attribute specifies the name of the directory in which the changelog database is created the first time the plug-in is run. By default, the database is stored with all the other databases under /var/ lib/dirsrv/slapd-instance_name/changelogdb .
NOTE
For performance reasons, store this database on a different physical disk.
The server has to be restarted for changes to this attribute to go into effect.
Parameter
Entry DN
Valid Values
Default Value
Syntax
Example
Description cn=Retro Changelog Plugin, cn=plugins, cn=config
Any valid path to the directory
None
DirectoryString nsslapd-changelogdir: /var/lib/dirsrv/ slapd-instance_name/changelogdb
3.6.2. nsslapd-changelogmaxage (Max Changelog Age)
This attribute specifies the maximum age of any entry in the changelog. The changelog contains a record for each directory modification and is used when synchronizing consumer servers. Each record contains a timestamp. Any record with a timestamp that is older than the value specified in this attribute is removed. If this attribute is absent, there is no age limit on changelog records, which is the default behavior since this attribute is not present by default.
NOTE
Expired changelog records will not be removed if there is an agreement that has fallen behind further than the maximum age.
Parameter
Entry DN
Valid Range
Default Value
Description cn=Retro Changelog Plugin, cn=plugins, cn=config
0 (meaning that entries are not removed according to their age) to the maximum 32 bit integer value (2147483647)

nsslapd-changelogmaxage: 30d
3.7. Distributed Numeric Assignment Plug-in Attributes
The Distributed Numeric Assignment Plug-in manages ranges of numbers and assigns unique numbers within that range to entries. By breaking number assignments into ranges, the Distributed
Numeric Assignment Plug-in allows multiple servers to assign numbers without conflict. The plug-in also manages the ranges assigned to servers, so that if one instance runs through its range quickly, it can request additional ranges from the other servers.
Distributed numeric assignment is handled per-attribute and is only applied to specific suffixes and specific entries within the subtree.
3.7.1. dnaFilter
This attribute sets an LDAP filter to use to search for and identify the entries to which to apply the distributed numeric assignment range.
The dnaFilter attribute is required to set up distributed numeric assignment for an attribute.
Parameter
Entry DN
Valid Range
Default Value
Syntax
Example
Description cn=Distributed Numeric Assignment Plugin, cn=plugins, cn=config
Any valid LDAP filter
None
DirectoryString dnaFilter: (objectclass=person)
3.7.2. dnaMagicRegen
This attribute sets a user-defined value that instructs the plug-in to assign a new value for the entry.
The magic value can be used to assign new unique numbers to existing entries or to use as a standard setting when adding new entries.
The magic entry should be outside of the defined range for the server so that it cannot accidentally be triggered. This attribute also does not have to a number, which can make it easier to assign.
Parameter
Entry DN
Valid Range
Default Value
Syntax
Description cn=Distributed Numeric Assignment Plugin, cn=plugins, cn=config
Any string
None
DirectoryString
207
Chapter 3. Plug-in Implemented Server Functionality Reference
Parameter
Example
Description dnaMagicRegen: magic
3.7.3. dnaMaxValue
This attribute sets the maximum value that can be assigned for the range. The default is -1, which is the same as setting the highest 64-bit integer.
Parameter
Entry DN
Valid Range
Default Value
Syntax
Example
Description cn=Distributed Numeric Assignment Plugin, cn=plugins, cn=config
1 to the maximum 32-bit integer on 32-bit systems and to the maximum 64-bit integer on
64-bit systems; -1 is unlimited
-1
Integer dnaMaxValue: 1000
3.7.4. dnaNextRange
This attribute defines the next range to use when the current range is exhausted. This value is automatically set when range is transferred between servers, but it can also be manually set to add a range to a server if range requests are not used.
The dnaNextRange attribute should be set explicitly only if a separate, specific range has to be assigned to other servers. Any range set in the dnaNextRange attribute must be unique from the available range for the other servers to avoid duplication. If there is no request from the other servers and the server where dnaNextRange is set explicitly has reached its set dnaMaxValue, the next set of values (part of the dnaNextRange) is allocated from this deck.
The dnaNextRange allocation is also limited by the dnaThreshold attribute that is set in the DNA configuration. Any range allocated to another server for dnaNextRange cannot violate the threshold for the server, even if the range is available on the deck of dnaNextRange.
NOTE
If the dnaNextRange attribute is handled internally if it is not set explicitly. When it is handled automatically, the dnaMaxValue attribute serves as upper limit for the next range.
The attribute sets the range in the format lower_range-upper_range.
Parameter
Entry DN
Valid Range
Description cn=Distributed Numeric Assignment Plugin, cn=plugins, cn=config
1 to the maximum 32-bit integer on 32-bit systems and to the maximum 64-bit integer on
64-bit systems for the lower and upper ranges
208
dnaNextValue
Parameter
Default Value
Syntax
Example
Description
None
DirectoryString dnaNextRange: 100-500
3.7.5. dnaNextValue
This attribute gives the next available number which can be assigned. After being initially set in the configuration entry, this attribute is managed by the Distributed Numeric Assignment Plug-in.
The dnaNextValue attribute is required to set up distributed numeric assignment for an attribute.
Parameter
Entry DN
Valid Range
Default Value
Syntax
Example
Description cn=Distributed Numeric Assignment Plugin, cn=plugins, cn=config
1 to the maximum 32-bit integer on 32-bit systems and to the maximum 64-bit integer on
64-bit systems
-1
Integer dnaNextValue: 1
3.7.6. dnaPrefix
This attributes defines a prefix that can be prepended to the generated number values for the attribute.
For example, to generate a user ID such as user1000, the dnaPrefix setting would be user.
Parameter
Entry DN
Valid Range
Default Value
Syntax
Example
Description cn=Distributed Numeric Assignment Plugin, cn=plugins, cn=config
Any string
None
DirectoryString dnaPrefix: id
3.7.7. dnaRangeRequestTimeout
One potential situation with the Distributed Numeric Assignment Plug-in is that one server begins to run out of numbers to assign. The dnaThreshold attribute sets a threshold of available numbers in the range, so that the server can request an additional range from the other servers before it is unable to perform number assignments.
The dnaRangeRequestTimeout attribute sets a timeout period, in seconds, for range requests so that the server does not stall waiting on a new range from one server and can request a range from a new server.
For range requests to be performed, the dnaSharedCfgDN attribute must be set.
209
Chapter 3. Plug-in Implemented Server Functionality Reference
Parameter
Entry DN

64-bit systems
10
Integer dnaRangeRequestTimeout: 15
3.7.8. dnaScope
This attribute sets the base DN to search for entries to which to apply the distributed numeric assignment. This is analogous to the base DN in an ldapsearch.
Parameter
Entry DN
Valid Range
Default Value
Syntax
Example
Description cn=Distributed Numeric Assignment Plugin, cn=plugins, cn=config
Any Directory Server entry
None
DirectoryString dnaScope: ou=people,dc=example,dc=com
3.7.9. dnaSharedCfgDN
This attribute defines a shared identity that the servers can use to transfer ranges to one another. This entry is replicated between servers and is managed by the plug-in to let the other servers know what ranges are available. This attribute must be set for range transfers to be enabled.
NOTE
The shared configuration entry must be configured in the replicated subtree, so that the entry can be replicated to the servers. For example, if the ou=People,dc=example,dc=com subtree is replicated, then the configuration entry must be in that subtree, such as ou=UID Number Ranges, ou=People,dc=example,dc=com .
The entry identified by this setting must be manually created by the administrator. The server will automatically contain a sub-entry beneath it to transfer ranges.
Parameter
Entry DN
Valid Range
Default Value
Description cn=Distributed Numeric Assignment Plugin, cn=plugins, cn=config
Any DN
None
210
dnaThreshold
Parameter
Syntax
Example
Description
DN dnaSharedCfgDN: cn=range transfer user, cn=config
3.7.10. dnaThreshold
One potential situation with the Distributed Numeric Assignment Plug-in is that one server begins to run out of numbers to assign, which can cause problems. The Distributed Numeric Assignment Plug-in allows the server to request a new range from the available ranges on other servers.
So that the server can recognize when it is reaching the end of its assigned range, the dnaThreshold attribute sets a threshold of remaining available numbers in the range. When the server hits the threshold, it sends a request for a new range.
For range requests to be performed, the dnaSharedCfgDN attribute must be set.
Parameter
Entry DN
Valid Range
Default Value
Syntax
Example
Description cn=Distributed Numeric Assignment Plugin, cn=plugins, cn=config
1 to the maximum 32-bit integer on 32-bit systems and to the maximum 64-bit integer on
64-bit systems
100
Integer dnaThreshold: 100
3.7.11. dnaType
This attribute sets which attribute has unique numbers being generated for it. In this case, whenever the attribute is added to the entry without a value or with the magic number, an assigned value is automatically supplied.
This is required to set up distributed numeric assignments for an attributes.
Parameter
Entry DN
Valid Range
Default Value
Syntax
Example
Description cn=Distributed Numeric Assignment Plugin, cn=plugins, cn=config
Any Directory Server attribute
None
DirectoryString dnaType: uidNumber
3.8. MemberOf Plug-in Attributes
Group membership is defined within group entries using an attribute such as member. Searching for the member attribute makes it easy to list all of the members for the group. However, group
211
Chapter 3. Plug-in Implemented Server Functionality Reference membership is not reflected in the member's user entry, so it is impossible to tell to what groups a person belongs by looking at the user's entry.
The MemberOf Plug-in synchronizes the group membership in group members with the members' individual directory entries by identifying changes to a specific attribute (such as member) in the group entry and then carrying those changes over to a specific attribute in the entries for the members.
3.8.1. memberofattr
This attribute specifies the attribute in the user entry for the Directory Server to manage to reflect group membership. The MemberOf Plug-in generates the value of the attribute specified here in the directory entry for the member. There is a separate attribute for every group to which the user belongs.
Parameter
Entry DN
Valid Range
Default Value
Syntax
Example
Description cn=MemberOf Plugin, cn=plugins, cn=config
Any Directory Server attribute memberOf
DirectoryString memberofattr: memberOf
3.8.2. memberofgroupattr
This attribute specifies the attribute in the group entry to use to identify the DNs of group members.
By default, this is the member attribute, but it can be any membership-related attribute, such as uniqueMember or member.
NOTE
Any attribute can be used for the memberofgroupattr value, but the MemberOf
Plug-in only works if the value of the target attribute contains the DN of the member entry. For example, the member attribute contains the DN of the member's user entry: member: uid=jsmith,ou=People,dc=example,dc=com
Some member-related attributes do not contain a DN, like the memberURL attribute.
That attribute will not work as a value for memberofgroupattr, since the memberURL value is a URL and a non-DN value cannot work with the MemberOf
Plug-in.
Parameter
Entry DN
Valid Range
Default Value
Syntax
Example
Description cn=MemberOf Plugin, cn=plugins, cn=config
Any Directory Server attribute member
DirectoryString memberofgroupattr: member

Chapter 4.
Server Instance File Reference
This chapter provides an overview of the files that are specific to an instance of Red Hat Directory
Server (Directory Server) — the files stored in the /etc/dirsrv/slapd-instance_name directory.
1 Having an overview of the files and configuration information stored in each instance of
Directory Server helps with understanding the file changes (or lack of file changes) which occur in the course of directory activity. It can also help to detect errors and intrusion by indicating what kind of changes to expect and, as a result, what changes are abnormal.
4.1. Overview of Directory Server Files
NOTE
In examples and sample code, paths assume that the Directory Server is installed in on Red Hat Enterprise Linux 5 (32-bit), which has an instance directory of /etc/ dirsrv/slapd-instance_name . If the Directory Server in a different platform, adjust the paths accordingly.
The files, tools, and scripts used by Directory Server are in the locations listed in the following directories.

4.2. Backup Files
Each Directory Server instance contains the following directory and file for storing backup-related files:
• /var/lib/dirsrv/slapd-instance_name/bak — This contains a directory dated with the instance_name, time and date of the database backup, such as
instance_name-2009_05_02_16_56_05/ , which in turn holds the database backup copy.
• /etc/dirsrv/slapd-instance_name/dse_original.ldif — This is a backup copy of the dse.ldif
configuration file from the time of installation.
4.3. Configuration Files
Each Directory Server instance stores its configuration files in the /etc/dirsrv/ slapd-instance_name directory. The configuration files in this directory are explained in
Section 2.1, “Overview of the Directory Server Configuration” .
4.4. Database Files
Each Directory Server instance contains the /var/lib/dirsrv/slapd-instance_name/db directory for storing all of the database files. The following is a sample listing of the /var/lib/ dirsrv/slapd-instance_name/db directory contents.
214
Database Files
__db.001 __db.003 __db.005 NetscapeRoot/
__db.002 __db.004 DBVERSION log.0000000007 userRoot/
Example 4.1. Database Directory Contents
• db.00x files — Used internally by the database and should not be moved, deleted, or modified in any way.
• log.xxxxxxxxxx files — Used to store the transaction logs per database.
• DBVERSION — Used for storing the version of the database.
• NetscapeRoot — Stores the o=NetscapeRoot database created by default when the setup- ds-admin.pl
script is run.
• userRoot — Stores the user-defined suffix (user-defined databases) created at setup; for example, dc=example,dc=com .
NOTE
If a new database is created (for example, testRoot) to store the directory tree under a new suffix, the directory named testRoot also appears in the /var/lib/ dirsrv/slapd-instance_name/db directory.
The following is a sample listing of the NetscapeRoot directory contents.
./ entrydn.db4* parentid.db4*
../ givenName.db4* sn.db4*
DBVERSION* id2entry.db4* uid.db4* aci.db4* nsUniqueId.db4* uniquemember.db4* ancestorid.db4* numsubordinates.db4* cn.db4* objectclass.db4*
Example 4.2. NetscapeRoot Database Directory Contents
The NetscapeRoot subdirectories contain an index_namedb4 file for every index currently defined in the database. In addition to these files, the NetscapeRoot and userRoot subdirectories contain the following files:
• ancestorid.db4 — Contains a list of IDs to find the ID of the entry's ancestor.
• entrydn.db4 — Contains a list of full DNs to find any ID.
• id2entry.db4 — Contains the actual directory database entries. All other database files can be recreated from this one, if necessary.
• nsuniqueid.db4 — Contains a list of unique IDs to find any ID.
• numsubordinates.db4 — Contains IDs that have child entries.
• objectclass.db4 — Contains a list of IDs which have a particular object class.
• parentid.db4 — Contains a list of IDs to find the ID of the parent.
215
Chapter 4. Server Instance File Reference
4.5. LDIF Files
Sample LDIF files are stored in the /var/lib/dirsrv/slapd-instance_name/ldif directory for
European.ldif
Example.ldif
Example-roles.ldif
Example-views.ldif
Example 4.3. LDIF Directory Contents
• European.ldif — Contains European character samples.
• Example.ldif — Is a sample LDIF file.
• Example-roles.ldif — Is a sample LDIF file similar to Example.ldif, except that it uses roles and class of service instead of groups for setting access control and resource limits for directory administrators.
NOTE
The LDIF files exported by db2ldif or db2ldif.pl scripts in the instance directory are stored in /var/lib/dirsrv/slapd-instance_name/ldif.
4.6. Lock Files
Each Directory Server instance contains a /var/lock/dirsrv/slapd-instance_name directory for storing lock-related files. The following is a sample listing of the locks directory contents.
exports/ imports/ server/
Example 4.4. Lock Directory Contents
The lock mechanisms stored in the exports, imports, and server subdirectories prevent multiple, simultaneous operations from conflicting with each other. The lock mechanisms allow for one server instance to run at a time, with possible multiple export jobs. They also permit one ldif2db import operation at a time (not ldif2db.pl, because multiple ldif2db.pl operations can be run at any time) to the exclusion of all export and slapd server operations.
If there are error messages indicating that the lock table is out of available locks (for example, libdb:
Lock table is out of available locks ), double the value of the nsslapd-db-locks attribute in the cn=config,cn=ldbm database,cn=plugins,cn=config entry.
For example, if the current value is 10000, set it to 20000. If the problem persists, double the number again. To monitor the current and maximum number of locks, do a search on cn=database, cn=monitor, cn=ldbm database, cn=plugins, cn=config . For example: ldapsearch -h localhost -p 389 -D "cn=directory manager" -w password
-b "cn=database,cn=monitor,cn=ldbm database, cn=plugins,cn=config" objectclass=* | grep
-- -locks: )
216
Log Files
For more information on using LDAP utilities, see the Directory Server Administrator's Guide.
4.7. Log Files
Each Directory Server instance contains a /var/log/dirsrv/slapd-instance_name directory for storing log files. The following is a sample listing of the /logs directory contents.
access access.20090228-171925 errors access.20090221-162824 access.rotationinfo errors.20090221-162824 access.20090223-171949 audit errors.rotationinfo
access.20090227-171818 audit.rotationinfo slapd.stats
Example 4.5. Log Directory Contents
• The content of the access, audit, and error log files is dependent on the log configuration.
• The slapd.stats file is a memory-mapped file which cannot be read by an editor. It contains data collected by the Directory Server SNMP data collection component. This data is read by the SNMP subagent in response to SNMP attribute queries and is communicated to the SNMP master agent responsible for handling Directory Server SNMP requests.
4.8. PID Files
slapd-serverID.pid
and slapd-serverID.startpid files are created in the /var/run/ dirsrv directory when the server is up and running. Both files store the server's process ID.
4.9. Tools
Directory Server tools are stored in three directories on Red Hat Enterprise Linux 5 (32-bit):
• /usr/bin
• /usr/sbin
• /usr/lib/mozldap

Log File Reference
Red Hat Directory Server (Directory Server) provides logs to help monitor directory activity. Monitoring helps quickly detecting and remedying failures and, where done proactively, anticipating and resolving potential problems before they result in failure or poor performance. Part of monitoring the directory effectively is understanding the structure and content of the log files.
This chapter does not provide an exhaustive list of log messages. However, the information presented in this chapter serves as a good starting point for common problems and for better understanding the information in the access, error, and audit logs.
Logs are kept per Directory Server instances and are located in the /var/log/dirsrv/ slapd-instance_name directory.
5.1. Access Log Reference
The Directory Server access log contains detailed information about client connections to the directory.
A connection is a sequence of requests from the same client with the following structure:
• Connection record, which gives the connection index and the IP address of the client.
• Bind record.
• Bind result record.
• Sequence of operation request/operation result pairs of records (or individual records in the case of connection, closed, and abandon records).
• Unbind record.
• Closed record.
Every line begins with a timestamp — [21/Apr/2009:11:39:51 -0700] — the format of which may vary depending on the platform. -0700 indicates the time difference in relation to GMT. Apart from the connection, closed, and abandon records, which appear individually, all records appear in pairs, consisting of a request for service record followed by a result record. These two records frequently appear on adjacent lines, but this is not always the case.
The access logs have different levels of logging, set in the nsslapd-accesslog-level attribute.
This section provides an overview of the default access logging content, log levels, and the content logged at different logging levels.

Section 5.1.1, “Access Logging Levels”
•
Section 5.1.2, “Default Access Logging Content”
•
Section 5.1.3, “Access Log Content for Additional Access Logging Levels”
NOTE
Directory Server provides a script which can analyze access logs to extract usage statistics and count the occurrences of significant events. For details about this script, see the logconv.pl
1 section.

Chapter 5. Log File Reference
5.1.1. Access Logging Levels
Different levels of access logging generate different amounts of detail and record different kinds of operations. The log level is set in the instance's nsslapd-accesslog-level 2
configuration attribute. The default level of logging is level 256, which logs access to an entry, but there are five different log levels available:
• 0 = No access logging.
• 4 = Logging for internal access operations.
• 256 = Logging for access to an entry.
• 512 = Logging for access to an entry and referrals.
• 131072 = Precise timing of operation duration. This gives microsecond resolution for the Elapsed
Time item in the access log.
This levels are additive, so to enable several different kinds of logging, add the values of those levels together. For example, to log internal access operations, entry access, and referrals, set the value of nsslapd-accesslog-level to 516 (512+4).
5.1.2. Default Access Logging Content
This section describes the access log content in detail based on the default access logging level extract shown below.

Example 5.1. Example Access Log
Connection Number
Every external LDAP request is listed with an incremental connection number, in this case conn=11, starting at conn=0 immediately after server startup.
[21/Apr/2009:11:39:51 -0700] conn=11 fd=608 slot=608 connection from 207.1.153.51 to
192.18.122.139
Internal LDAP requests are not recorded in the access log by default. To activate the logging of internal access operations, specify access logging level 4 on the nsslapd-accesslog-level 3 configuration attribute.
File Descriptor
Every connection from an external LDAP client to Directory Server requires a file descriptor or socket descriptor from the operating system, in this case fd=608. fd=608 indicates that it was file descriptor number 608 out of the total pool of available file descriptors which was used.
[21/Apr/2009:11:39:51 -0700] conn=11 fd=608 slot=608 connection from 207.1.153.51 to
192.18.122.139
Slot Number
The slot number, in this case slot=608, is a legacy part of the access log which has the same meaning as file descriptor. Ignore this part of the access log.
[21/Apr/2009:11:39:51 -0700] conn=11 fd=608 slot=608 connection from 207.1.153.51 to
192.18.122.139
Operation Number
To process a given LDAP request, Directory Server will perform the required series of operations. For a given connection, all operation request and operation result pairs are given incremental operation numbers beginning with op=0 to identify the distinct operations being performed.

Chapter 5. Log File Reference
[21/Apr/2009:11:39:51 -0700] conn=11 op=0 RESULT err=0 tag=97 nentries=0 etime=0
In Section 5.1.2, “Default Access Logging Content”
, we have op=0 for the bind operation request and result pair, then op=1 for the LDAP search request and result pair, and so on. The entry op=-1 in the access log generally means that the LDAP request for this connection was not issued by an external
LDAP client but, instead, initiated internally.
Method Type
The method number, in this case method=128, indicates which LDAPv3 bind method was used by the client.
[21/Apr/2009:11:39:51 -0700] conn=11 op=0 BIND dn="cn=Directory Manager" method=128 version=3
There are three possible bind method values:
• 0 for authentication
• 128 for simple bind with user password
• sasl for SASL bind using external authentication mechanism
Version Number
The version number, in this case version=3, indicates the LDAP version number (either LDAPv2 or
LDAPv3) that the LDAP client used to communicate with the LDAP server.
[21/Apr/2009:11:39:51 -0700] conn=11 op=0 BIND dn="cn=Directory Manager" method=128 version=3
Error Number
The error number, in this case err=0, provides the LDAP result code returned from the LDAP operation performed. The LDAP error number 0 means that the operation was successful. For a more comprehensive list of LDAP result codes, see
Section 5.4, “LDAP Result Codes”
.
[21/Apr/2009:11:39:51 -0700] conn=11 op=0 RESULT err=0 tag=97 nentries=0 etime=0
Tag Number
The tag number, in this case tag=97, indicates the type of result returned, which is almost always a reflection of the type of operation performed. The tags used are the BER tags from the LDAP protocol.
[21/Apr/2009:11:39:51 -0700] conn=11 op=0 RESULT err=0 tag=97 nentries=0 etime=0
Tag tag=97 tag=100 tag=101 tag=103 tag=105
Description
A result from a client bind operation.
The actual entry being searched for.
A result from a search operation.
A result from a modify operation.
A result from an add operation.
222
Default Access Logging Content
Tag tag=107 tag=109 tag=111 tag=115
Description
A result from a delete operation.
A result from a moddn operation.
A result from a compare operation.
A search reference when the entry on which the search was performed holds a referral to the required entry. Search references are expressed in terms of a referral.
A result from an extended operation.
tag=120
Table 5.1. Commonly-Used Tags
NOTE tag=100 and tag=115 are not result tags as such, and so it is unlikely that they will be recorded in the access log.
Number of Entries nentries shows the number of entries, in this case nentries=0, that were found matching the
LDAP client's request.
[21/Apr/2009:11:39:51 -0700] conn=11 op=0 RESULT err=0 tag=97 nentries=0 etime=0
Elapsed Time etime shows the elapsed time, in this case etime=3, or the amount of time (in seconds) that it took the Directory Server to perform the LDAP operation.
[21/Apr/2009:11:39:51 -0700] conn=11 op=1 RESULT err=0 tag=101 nentries=1 etime=3 notes=U
An etime value of 0 means that the operation actually took milliseconds to perform. To have microsecond resolution for this item in the access log, enter a value of 131328 (256+131072) in the nsslapd-accesslog-level configuration attribute.
LDAP Request Type
The LDAP request type indicates the type of LDAP request being issued by the LDAP client. Possible values are:
• SRCH for search
• MOD for modify
• DEL for delete
• ADD for add
• MODDN for moddn
• EXT for extended operation
223
Chapter 5. Log File Reference
• ABANDON for abandon operation
If the LDAP request resulted in sorting of entries, then the message SORT serialno will be recorded in the log, followed by the number of candidate entries that were sorted. For example:
[04/May/2009:15:51:46 -0700] conn=114 op=68 SORT serialno (1)
The number enclosed in parentheses specifies the number of candidate entries that were sorted, which in this case is 1.
LDAP Response Type
The LDAP response type indicates the LDAP response being issued by the LDAP client. There are three possible values:
• RESULT
• ENTRY
• REFERRAL, an LDAP referral or search reference
Unindexed Search Indicator
The unindexed search indicator, notes=U, indicates that the search performed was unindexed, which means that the database itself had to be directly searched instead of the index file. Unindexed searches occur in three scenarios:
• When the nsslapd-idlistscanlimit was reached within the index file used for the search.
• When no index file existed.
• When the index file was not configured in the way required by the search.
NOTE
An unindexed search indicator is often accompanied by a large etime value, as unindexed searches are generally more time consuming.
VLV-Related Entries
When a search involves virtual list views (VLVs), appropriate entries are logged in the access log file.
Similar to the other entries, VLV-specific entries show the request and response information side by side:
VLV RequestInformation ResponseInformation
RequestInformation has the following form: beforeCount:afterCount:index:contentCount
If the client uses a position-by-value VLV request, the format for the first part, the request information would be beforeCount: afterCount: value.
ResponseInformation has the following form:
224
Default Access Logging Content
targetPosition:contentCount (resultCode)
The example below highlights the VLV-specific entries:
[07/May/2009:11:43:29 -0700] conn=877 op=8530 SRCH base="(ou=People)" scope=2 filter="(uid=*)"
[07/May/2009:11:43:29 -0700] conn=877 op=8530 SORT uid
[07/May/2009:11:43:29 -0700] conn=877 op=8530 VLV 0:5:0210 10:5397 (0)
[07/May/2009:11:43:29 -0700] conn=877 op=8530 RESULT err=0 tag=101 nentries=1 etime=0
In the above example, the first part, 0:5:0210, is the VLV request information:
• The beforeCount is 0.
• The afterCount is 5.
• The value is 0210.
The second part, 10:5397 (0), is the VLV response information:
• The targetPosition is 10.
• The contentCount is 5397.
• The (resultCode) is (0).
Search Scope
The entry scope=n defines the scope of the search performed, and n can have a value of 0, 1, or 2.
• 0 for base search
• 1 for one-level search
• 2 for subtree search
For more information about search scopes, see "Using ldapsearch" in Appendix B, "Finding Directory
Entries", in the Red Hat Directory Server Administrator's Guide.
Extended Operation OID
An extended operation OID, such as EXT oid="2.16.840.1.113730.3.5.3" or EXT oid="2.16.840.1.113730.3.5.5" in
Example 5.1, “Example Access Log”

Change Sequence Number
The change sequence number, in this case csn=3b4c8cfb000000030000, is the replication change sequence number, indicating that replication is enabled on this particular naming context.
Abandon Message
The abandon message indicates that an operation has been aborted.
[21/Apr/2009:11:39:52 -0700] conn=12 op=2 ABANDON targetop=1 msgid=2 nentries=0 etime=0 nentries=0 indicates the number of entries sent before the operation was aborted, etime=0 value indicates how much time (in seconds) had elapsed, and targetop=1 corresponds to an operation value from a previously initiated operation (that appears earlier in the access log).
There are two possible log ABANDON messages, depending on whether the message ID succeeds in locating which operation was to be aborted. If the message ID succeeds in locating the operation (the targetop ) then the log will read as above. However, if the message ID does not succeed in locating the operation or if the operation had already finished prior to the ABANDON request being sent, then the log will read as follows:
[21/Apr/2009:11:39:52 -0700] conn=12 op=2 ABANDON targetop=NOTFOUND msgid=2 targetop=NOTFOUND indicates the operation to be aborted was either an unknown operation or already complete.
Message ID
The message ID, in this case msgid=2, is the LDAP operation identifier, as generated by the LDAP
SDK client. The message ID may have a different value than the operation number but identifies the same operation. The message ID is used with an ABANDON operation and tells the user which client operation is being abandoned.
226
Access Log Content for Additional Access Logging Levels
[21/Apr/2009:11:39:52 -0700] conn=12 op=2 ABANDON targetop=NOTFOUND msgid=2
NOTE
The Directory Server operation number starts counting at 0, and, in the majority of LDAP SDK/client implementations, the message ID number starts counting at
1, which explains why the message ID is frequently equal to the Directory Server operation number plus 1.
SASL Multi-Stage Bind Logging
In Directory Server, logging for multi-stage binds is explicit. Each stage in the bind process is logged.
The error codes for these SASL connections are really return codes. In Example 5.1, “Example
, the SASL bind is currently in progress so it has a return code of err=14, meaning the connection is still open, and there is a corresponding progress statement, SASL bind in progress .
[21/Apr/2009:11:39:55 -0700] conn=14 op=0 BIND dn="" method=sasl version=3 mech=DIGEST-MD5
[21/Apr/2009:11:39:55 -0700] conn=14 op=0 RESULT err=14 tag=97 nentries=0 etime=0, SASL bind
in progress
In logging a SASL bind, the sasl method is followed by the LDAP version number mechanism used, as shown below with the GSS-API mechanism.

and the SASL
[21/Apr/2009:12:57:14 -0700] conn=32 op=0 BIND dn="" method=sasl version=3 mech=GSSAPI
NOTE
The authenticated DN (the DN used for access control decisions) is now logged in the
BIND result line as opposed to the bind request line, as was previously the case:
[21/Apr/2009:11:39:55 -0700] conn=14 op=1 RESULT err=0 tag=97 nentries=0
etime=0 dn="uid=jdoe,dc=example,dc=com"
For SASL binds, the DN value displayed in the bind request line is not used by the server and, as a consequence, is not relevant. However, given that the authenticated
DN is the DN which, for SASL binds, must be used for audit purposes, it is essential that this be clearly logged. Having this authenticated DN logged in the bind result line avoids any confusion as to which DN is which.

Options Description
The options description (options=persistent) indicates that a persistent search is being performed, as distinguished from a regular search operation. Persistent searches can be used as a form of monitoring and configured to return changes to given configurations as changes occur; this is explained more in the ldapsearch chapter of the Administrator's Guide.
Both log levels 512 and 4 are enabled for this example, so both internal access operations and entry access and referrals being logged.

Common Connection Codes
5.1.4. Common Connection Codes
A connection code is a code that is added to the closed log message to provide additional information related to the connection closure.

T2
U1
Description
Client aborts the connection.
Corrupt BER tag encountered. If BER tags, which encapsulate data being sent over the wire, are corrupt when they are received, a B1 connection code is logged to the access log.
BER tags can be corrupted due to physical layer network problems or bad LDAP client operations, such as an LDAP client aborting before receiving all request results.
BER tag is longer than the nsslapd- maxbersize attribute value. For further information about this configuration attribute, see
Section 2.3.1.76, “nsslapd-maxbersize
Corrupt BER tag encountered.
Server failed to flush data response back to client.
Closed or corrupt connection has been detected.
Client does not receive a result within the specified idletimeout period. For further information about this configuration attribute, see
Section 2.3.1.60, “nsslapd-idletimeout (Default
Server closed connection after ioblocktimeout period was exceeded. For further information about this configuration
attribute, see Section 2.3.1.62, “nsslapdioblocktimeout (IO Block Time Out)” .
Connection closed by server after client sends an unbind request. The server will always close the connection when it sees an unbind request.
Table 5.3. Common Connection Codes
5.2. Error Log Reference
The Directory Server error log records messages for Directory Server transactions and operations.
These may be error messages for failed operations, but it also contains general information about the processes of Directory Server and LDAP tasks, such as server startup messages, logins and searches of the directory, and connection information.
229
Chapter 5. Log File Reference
5.2.1. Error Log Logging Levels
The error log can record different amounts of detail for operations, as well as different kinds of information depending on the type of error logging enabled.
The logging level is set in the nsslapd-errorlog-level 5
configuration attribute. The default log level is
16384 , which included critical error messages and standard logged messages, like LDAP results codes and startup messages. As with access logging, error logging levels are additive. To enable both replication logging (8192) and plug-in logging (65536), set the log level to 73728 (8192 + 65536).
NOTE
Enabling high levels of debug logging can significantly erode server performance.
Debug log levels, such as replication (8192) should only be enabled for troubleshooting, not for daily operations.

Housekeeping thread debugging.
Logs detailed information about every replication-related operation, including updates and errors, which is important for debugging replication problems.
Default level of logging used for critical errors and other messages that are always written to the error log, such as server startup messages.
Messages at this level are always included in the error log, regardless of the log level setting.
Database entry cache debugging.
Writes an entry to the log file when a server plug-in calls slapi-log-error , so this is used for server plug-in debugging.
Microsecond resolution for timestamps instead of the default seconds. This cannot be enabled in the Directory
Server Console.
Summarizes information about access to the server, much less verbose than level 128.
This value is recommended for use when a summary of access control processing is needed. Use 128 for very detailed processing messages.
Table 5.4. Error Log Levels
5.2.2. Error Log Content
The error log format is simpler than the access log entries. It is also more flexible because the kind of information returned depends on the service or operation which is writing the log entry. Generally, error log entries contain the following elements:
• A timestamp, such as [05/Jan/2009:02:27:22 -0500], although the format varies depending on the platform. The ending four digits, -0500, indicate the time difference in relation to GMT.
231
Chapter 5. Log File Reference
• The plug-in being called, for internal operations.
• Functions called by the plug-in, for internal operations.
• Messages returned by the plug-in or operation, which may include LDAP error codes, connection information, or entry information.
Frequently, the messages for an operation appear on multiple lines of the log, but these are not identified with a connection number or operation number.
includes some task information, critical errors, and server startup messages.

Example 5.3. Error Log Excerpt
5.2.3. Error Log Content for Other Log Levels
The different log levels return not only different levels of detail, but also information about different types of server operations. Some of these are summarized here, but there are many more combinations of logging levels possible.
Replication logging is one of the most important diagnostic levels to implement. This logging level records all operations related to replication and Windows synchronization, including processing modifications on a supplier and writing them to the changelog, sending updates, and changing replication agreements.
Whenever a replication update is prepared or sent, the error log identifies the replication or synchronization agreement being specified, the consumer host and port, and the current replication task.

Example 5.4. Replication Error Log Entry
Plug-in logging records every the name of the plugin and all of the functions called by the plugin. This has a simple format:
[timestamp] Plugin_name - message
[timestamp] - function - message
The information returned can be hundreds of lines long as every step is processed. The precise information recorded depends on the plug-in itself. For example, the ACL Plug-in includes a connection and operation number, as shown in

Example 5.5. Example ACL Plug-in Error Log Entry with Plug-in Logging
234
Audit Log Reference
NOTE
Example 5.5, “Example ACL Plug-in Error Log Entry with Plug-in Logging” shows both
plug-in logging and search filter processing (log level 32).
Many other kinds of logging have similar output to the plug-in logging level, only for different kinds of internal operations. Heavy trace output (4), access control list processing (128), schema parsing
(2048), and housekeeping (4096) all record the functions called by the different operations being performed. In this case, the difference is not in the format of what is being recorded, but what operations it is being recorded for.
The configuration file processing goes through any .conf file, printing every line, whenever the server starts up. This can be used to debug any problems with files outside of the server's normal configuration. By default, only slapd-collations.conf file, which contains configurations for international language sets, is available.

Example 5.6. Config File Processing Log Entry
There are two levels of ACI logging, one for debug information and one for summary. Both of these
ACI logging levels records some extra information that is not included with other types of plug-ins or error logging, including connection 6 and operation 7 information. Show the name of the plug-in, the bind DN of the user, the operation performed or attempted, and the ACI which was applied. The debug level shows the series of functions called in the course of the bind and any other operations, as well.
Example 5.7, “Access Control Summary Logging”
shows the summary access control log entry.
[09/Jan/2009:16:02:01 -0500] NSACLPlugin - #### conn=24826547353419844 op=1

5.3. Audit Log Reference
The audit log records changes made to the server instance. Unlike the error and access log, the audit log does not record access to the server instance, so searches against the database are not logged.
The audit log is formatted differently than the access and error logs and is basically like a timestamped LDIF file. The operations recorded in the audit log are formatted as LDIF statements:

Command-Line Utilities
This chapter contains reference information on command-line utilities used with Red Hat Directory
Server (Directory Server). These command-line utilities make it easy to perform administration tasks on the Directory Server.
6.1. Finding and Executing Command-Line Utilities
The ldapsearch, ldapmodify, ldapdelete, and ldappasswd command-line utilities are provided as a separate package, called either mozldap-tools or mozldap6-tools, and the utilities are installed in /usr/lib/mozldap or /usr/lib/mozldap6, respectively. Depending on the package installed on the system, add the path to the PATH environment variable to use the command-line utilities.
NOTE
For most Linux systems, OpenLDAP tools are already installed in the /usr/bin/ directory. These OpenLDAP tools are not supported for Directory Server operations.
For the best results with the Directory Server, make sure the path to the Mozilla
LDAP tools comes first in the PATH or use the full path and file name for every LDAP operation. To use Mozilla LDAP tools, ensure that /usr/lib/mozldap or /usr/ lib/mozldap6 appears in the PATH variable before /usr/bin.
These OpenLDAP tools can be used for Directory Server operations with certain cautions:
• The output of the other tools may be different, so it may not look like the examples in the documentation.
• The OpenLDAP tools require a -x argument to disable SASL so that it can be used for a simple bind, meaning the -D and -w arguments or an anonymous bind.
• The OpenLDAP tools' arguments for using TLS/SSL and SASL are quite different than the Mozilla LDAP arguments. See the OpenLDAP documentation for instructions on those arguments.
The ldif and dbscan command-line utilities are stored in the /usr/bin directory.
6.2. Using Special Characters
When using the ldapsearch command-line utility, it may be necessary to specify values that contain characters that have special meaning to the command-line interpreter, such as space ( ), asterisk (*), and backslash (\). When this situation occurs, enclose the value in quotation marks (""). For example:
-D "cn=Barbara Jensen, ou=Product Development, dc=example,dc=com"
Depending on the command-line interpreter, use either single or double quotation marks for this purpose. See the operating system documentation for more information.
Additionally, commas in DN values must be escaped with a backslash. For example:
239
Chapter 6. Command-Line Utilities
-D "cn=Patricia Fuentes, ou=people, dc=example,dc=Bolivia\, S.A."
6.3. Command-Line Utilities Quick Reference
The following table provides a summary of the command-line utilities provided for Directory Server.
Command-Line Utility ldapsearch ldapmodify ldapdelete ldappasswd ldif dbscan
Table 6.1. Commonly-Used Command-Line Utilities
Description
Searches the directory and returns search results in LDIF format. For details on this tool, see the "Finding Directory Entries" appendix in the Directory Server Administrator's Guide.
Adds, deletes, modifies, or renames entries.
All operations are specified using LDIF update statements. For details on this tool, see "Adding and Modifying Entries Using ldapmodify" in the "Creating Directory Entries" chapter in the
Directory Server Administrator's Guide.
Deletes entries in the directory. For information on using this utility, see "Deleting Entries Using ldapdelete" in the "Creating Directory Entries" chapter in the Directory Server Administrator's
Guide.
Changes users passwords with the password change extended operation. For more information on the password extended change operation, see the "Managing the Password
Policy" section of the "Managing User Accounts and Passwords" chapter in the Directory Server
Administrator's Guide.
Automatically formats LDIF files and creates base 64-encoded attribute values. For details on this tool, see appendix A in the Directory Server
Administrator's Guide.
Analyzes and extracts information from a
Directory Server database file.
6.4. ldapsearch
ldapsearch is a configurable utility that locates and retrieves directory entries via LDAP. This utility opens a connection to the specified server using the specified distinguished name and password and locates entries based on a specified search filter. Search scopes can include a single entry, an entry's immediate subentries, or an entire tree or subtree. Search results are returned in LDIF format.

•
Syntax ldapsearch -b basedn -s scope [ optional_options ] "(attribute=filter)" [ optional_list_of_attributes ]
For any value that contains a space ( ), the value should be enclosed in double quotation marks. For example:
-b "ou=groups, dc=example,dc=com"
Option optional_options
"(filter)" optional_list_of_attributes
Description
A series of command-line options. These must be specified before the search filter, if used.
An LDAP search filter as described in Directory
Server Administrator's Guide. Do not specify a search filter if search filters are supplied in a file using the -f option.
A list of space-separated attributes that reduce the scope of the attributes returned in the search results. This list of attributes must appear after the search filter. For a usage example, see the
Directory Server Administrator's Guide. If a list of attributes is not specified, the search returns values for all attributes permitted by the access control set in the directory with the exception of operational attributes.
Table 6.2. ldapsearch Syntax
To return operational attributes as a result of a search operation, they must be explicitly specified in the search command. To retrieve regular attributes along with explicitly-specified operational attributes, specify an asterisk (*) in addition to the operational attributes.
Commonly-Used ldapsearch Options
Table 6.3, “Commonly-Used ldapsearch Options”
lists the most commonly used ldapsearch command-line options.
The most common ldapsearch usage specifies the host and port number, bind DN and password, scope, base DN, and a filter that returns every entry under the search base: ldapsearch -b basedn -s sub -h host -p port -D binddn -w password "(objectclass=*)"
241
Chapter 6. Command-Line Utilities
Option
-b
-D
-g
-h
Description
Specifies the starting point for the search. The value specified here must be a distinguished name that currently exists in the database.
This option is optional if the LDAP_BASEDN environment variable has been set to a base DN.
The value specified in this option should be provided in double quotation marks. For example:
-b "cn=Barbara Jensen, ou=Product
Development, dc=example,dc=com"
The root DSE entry is a special entry that contains a list of all the suffixes supported by the local directory. To search this entry, supply a search base of "", a search scope of base, and a filter of "objectclass=*". For example:
-b "" -s base "objectclass=*"
Specifies the distinguished name with which to authenticate to the server. This option is optional if anonymous access is supported by the server. If specified, this value must be a DN recognized by the Directory Server, and it must also have the authority to search for the entries.
For example:
-D "uid=bjensen, dc=example,dc=com"
Specifies that the password policy request control not be sent with the bind request. By default, the new LDAP password policy request control is sent with bind requests.
The ldapsearch tool can parse and display information from the response control if it is returned by a server; that is, the tool will print an appropriate error or warning message when a server sends the password policy response control with the appropriate value.
The criticality of the request control is set to false to ensure that all LDAPv3 servers that do not understand the control can ignore it. To suppress sending of the request control with the bind request, include -g on the command-line.
Specifies the hostname or IP address of the machine on which the Directory Server is
242
-p
-s
Option
-l
-w ldapsearch
Description installed. If a host is not specified, ldapsearch uses the local host. For example:
-h mozilla
Specifies the maximum number of seconds to wait for a search request to complete. For example:
-l 300
Regardless of the value specified here, ldapsearch will never wait longer than is allowed by the server's nsslapd-timelimit attribute, unless the authenticated user is the Directory Manager. The default value for the nsslapd-timelimit attribute is 3600
seconds. See Section 2.3.1.106, “nsslapdtimelimit (Time Limit)” for more information.
Specifies the TCP port number that the Directory
Server uses. For example:
-p 1049
The default is 389. If -Z is used, the default is
636 .
Specifies the scope of the search. The scope can be one of the following:
• base searches only the entry specified in the
-b option or defined by the LDAP_BASEDN environment variable.
• one searches only the immediate children of the entry specified in the -b option. Only the children are searched; the actual entry specified in the -b option is not searched.
• sub searches the entry specified in the - b option and all of its descendants. That is, perform a subtree search starting at the point identified in the -b option. This is the default.
Specifies the password associated with the distinguished name that is specified in the -D option. For example:
-w diner892
If this option is not specified, anonymous access is used.
243
Chapter 6. Command-Line Utilities
Option
-x
-z
Description
If a dash (-) is used as the password value, the utility prompts for the password after the command is entered. This avoids having the password on the command line.
Specifies that the search results are sorted on the server rather than on the client. This is useful to sort according to a matching rule, as with an international search. In general, it is faster to sort on the server rather than on the client.
Specifies the maximum number of entries to return in response to a search request. For example:
-z 1000
Normally, regardless of the value specified here, ldapsearch never returns more entries than the number allowed by the server's nsslapd- sizelimit attribute, unless the authenticated user is the Directory Manager. However, this limitation can be overridden by binding as the root DN when using this commandline argument. This is because binding as the root DN causes this option to default to zero (0). The default value for the nsslapd- sizelimit attribute is 2000 entries. See
Section 2.3.1.103, “nsslapd-sizelimit (Size Limit)”
for more information.
Table 6.3. Commonly-Used ldapsearch Options
Persistent Search Options
A persistent search leaves the search operation open after the initial search results are returned.
This allows the entries returned in the search to remain in cache and updates to be transmitted and included as they occur. Persistent searches leave the ldapsearch open until the client closes the connection. Using persistent searches is described in the "Finding Directory Entries" appendix of the
Administrator's Guide 1 .
ldapsearch -r -C PS:changetype[:changesonly[:entrychgcontrols]] -b dc=example,dc=com
objectclass=*
In the access logs, a persistent search is identifies with the tag options=persistent.
Option
-C
-r
Description
Runs the ldapsearch as a persistent search.
Prints all of the output from the ldapsearch command from the buffer immediately. This
1
../../ag/persistent-search.html
244
ldapsearch
Option
PS:changetype changesonly entrychgcontrols
Description is useful with the -C for persistent searches because it prints any entry modifications without delay and without the search hanging. It can also be used with other ldapsearches, not only persistent searches.
Specifies which types of changes to entries allow the entry to be returned in the persistent search.
There are four options:
• add
• delete
• modify
• moddn (modrdn)
• all
Sets whether to return all existing entries which match the search filter (0) or only to return matching entries when the entry is modified (1).
The default is 1.
Sets whether to send entry change controls, additional information about the modification made to the entry. If the value is set to 0, then only the entry is returned. If the value is set to 1, then a line is added to the entry as it is returned to the persistent search that lists the changetype performed on the entry. The default is 1.
Table 6.4. Persistent Search Options
SSL Options
The following command-line options can be used to specify that ldapsearch use LDAPS when communicating with an SSL-enabled Directory Server or used for certificate-based authentication.
These options are valid only when LDAPS has been turned on and configured for the Directory Server.
For information on certificate-based authentication and creating a certificate database for use with
LDAP clients, see the "Managing SSL" chapter in the Directory Server Administrator's Guide.
In addition to the standard ldapsearch options such as the base (-b), scope (-s), and filter, the follow options are required to run an ldapsearch command using SSL:
• -p with the Directory Server secure port
• -Z to specify to use SSL (or, alternatively, -ZZ or -ZZZ to specify Start TLS)
• -P to give certificate database's filename and path
• -N to give the SSL certificate name
• -K to specify the private key database's filename and path
• -W to give the password to the private key database
245
Chapter 6. Command-Line Utilities
Option
-3
-I
-K
-m
-N
-P
Description
Specifies that hostnames should be checked in
SSL certificates.
Specifies the SSL key password file that contains the token:password pair.
Specifies the absolute path, including the filename, of the private key database of the client.
The -K option must be specified when the key database has a different name than key3.db or when the key database is not under the same directory as the certificate database, the cert8.db
file (the path which is specified with the -P option).
Specifies the path to the security module database, such as /etc/dirsrv/ slapd-instance_name/secmod.db
. This option only need to be given if the security module database is in a different directory than the certificate database itself.
Specifies the certificate name to use for certificate-based client authentication, such as -
N "Server-Cert" . If this option is specified, then the -Z, -P, and -W options are required.
Also, if this option is specified, then the -D and
-w options must not be specified, or certificatebased authentication will not occur, and the bind operation will use the authentication credentials specified on -D and -w.
Specifies the absolute path, including the option, of the certificate database of the client. This option is used only with the -Z option.
When used on a machine where an SSL-enabled web browser is configured, the path specified on this option can be that of the certificate database for the browser. For example:
-P /security/cert.db
The client security files can also be stored on the Directory Server in the /etc/dirsrv/ slapd-instance_name directory. In this case, the -P option would call out a path and filename similar to the following:
-P /etc/dirsrv/slapd-instance_name/clientcert.db
246
ldapsearch
Option
-Q
-W
-W -
-Z
-ZZ
-ZZZ
Description
Specifies the token and certificate name, which is separated by a semi-colon (:) for PKCS11.
Specifies the password for the private key database identified in the -P option. For example:
-W secret
If a dash (-) is used as the password value, the utility prompts for the password after the command is entered. This avoids having the password on the command line.
Prompts for the password for the token database.
Specifies that SSL is to be used for the search request.
Specifies the Start TLS request. Use this option to make a cleartext connection into a secure one. If the server does not support Start TLS, the command does not have to be aborted; it will continue in cleartext.
Enforces the Start TLS request. The server must respond that the request was successful.
If the server does not support Start TLS, such as Start TLS is not enabled or the certificate information is incorrect, the command is aborted immediately.
Table 6.5. Additional SSL ldapsearch Options
SASL Options
SASL mechanisms can be used to authenticate a user, using the -o the required SASL information.
To learn which SASL mechanisms are supported, search the root DSE. See the -b option in Table 6.3,
“Commonly-Used ldapsearch Options” .
Option
-o
Description
Specifies SASL options. The format is -o
saslOption=value. saslOption can have one of six values:
• mech, the SASL authentication mechanism

247
Chapter 6. Command-Line Utilities
Option Description
• secProp, the security properties
• realm, the Kerberos realm
• flags
The expected values depend on the supported mechanism. The -o can be used multiple times to pass all of the required SASL information for the mechanism. For example:
-o "mech=DIGEST-MD5" -o "authzid=test_user" o "authid=test_user"
Table 6.6. SASL Options

-f
-G
-H
-i ldapsearch
Description
Minimizes the base-64 encoding for the values of returned entries.
Specifies a different separator. This option allows a separator other than a colon (:) to separate an attribute name from the corresponding value. For example:
-F +
Specifies the file containing the search filters to be used in the search. For example:
-f search_filters option to supply a search filter directly to the command line.
For more information about search filters, see
Appendix B, "Finding Directory Entries", in the
Directory Server Administrator's Guide.
Conducts a virtual list view search. This option can set the number of entries before or after the search target and the index or value of the first entry returned.
For example, a value operation that sorts by surname, -G 20:30:johnson, returns the first entry with a surname equal to or less than johnson , in addition to 20 entries that come before it and 30 entries that come after it. If there are fewer matching entries in the directory than the before or after number requested by the search, all available entries before/after the search target that match the search criteria are returned.
An index operation which sorts by surname, -
G 20:30:100:0 , returns from the 80th through
130th entries sorted by sn. Use 0 as the fourth value for the count number unless you know how many entries the VLV index has.
Prints the help information.
Specifies the characterset to use for commandline input. The default is the characterset specified in the LANG environment variable. Use this option to perform the conversion from the specified characterset to UTF8, thus overriding the environment variable setting.
253
-n
-O
Chapter 6. Command-Line Utilities
Option
-J
-j filename
-k
-M
Description
This argument can input the bind DN, base DN, and the search filter pattern in the specified characterset.
ldapsearch converts the input from these arguments before it processes the search request. For example, -i no indicates that the bind DN, base DN, and search filter are provided in Norwegian. This argument only affects the command-line input; that is, if a file containing a search filter (with the -f option) is specified, ldapsearch will not convert the data in the file.
Send an arbitrary control. This option can be used in the following format to retrieve access control information on a specific entry:
-J control OID:boolean criticality:dn:AuthID
• control OID is the OID for the get effective rights control,
1.3.6.1.4.1.42.2.27.9.5.2
.
• boolean criticality specifies whether the search operation should return an error if the server does not support this control (true) or if it should be ignored and let the search return as normal (false).
• AuthId is the DN of the user whose rights to check.
Contains the name of a file containing the password for the bind DN.
Bypasses converting the password to UTF8.
Manages smart referrals. This causes the server not to return the smart referral contained on the entry but, instead, to return the actual entry containing the referral. Use this option to search for entries that contain smart referrals. For more information about smart referrals, see the
"Configuring Directory Databases" chapter in the
Directory Server Administrator's Guide.
Specifies that the search is not actually to be performed, but that ldapsearch is to show what it would do with the specified input.
Specifies the maximum number of referral hops ldapsearch should automatically follow. For example:
254
-U
-u
-V
-T
-t
-v
-w -
-Y
Option
-R
-S ldapsearch
Description
-O 2
Specifies that referrals are not to be followed automatically. By default, referrals are followed automatically.
Specifies the attribute to use as the sort criteria.
For example:
-S sn
Use multiple -S arguments to further define the sort order. In the following example, the search results will be sorted first by surname and then by given name:
-S sn -S givenname
The default is not to sort the returned entries.
Specifies that no line breaks should be used within individual values in the search results.
Specifies that the results be written to a set of temporary files. With this option, each attribute value is placed in a separate file within the system temporary directory. No base-64 encoding is performed on the values, regardless of the content.
Creates file URLs for the files produced by the - t option.
Specifies that the user-friendly form of the distinguished name be used in the output.
Specifies the LDAP version number to be used on the search. For example:
-V 2
LDAPv3 is the default. An LDAPv3 search cannot be performed against a Directory Server that only supports LDAPv2.
Specifies that the utility is to run in verbose mode.
Prompts for the password for the bind DN.
Specifies the proxy DN to use for the search. This argument is provided for testing purposes. For more information about proxied authorization, see the "Managing Access
Control" chapter in the Directory Server
Administrator's Guide.

Description
Adds LDIF entries to the directory without requiring the changetype:add LDIF update statement. This provides a simplified method of adding entries to the directory. This option also allows directly adding a file created by ldapmodify .
Specifies the suffix under which the new entries will be added.
Specifies the distinguished name with which to authenticate to the server. The value must be a DN recognized by the Directory Server, and it must also have the authority to modify the entries. For example:
256
Option
-f
-g
-h
-p
-q ldapmodify
Description
-D "uid=bjensen, dc=example,dc=com"
This option cannot be used with the -N option.
Option that specifies the file containing the LDIF update statements used to define the directory modifications. For example:
-f modify_statements
If this option is not supplied, the update statements are read from stdin.
For information on supplying LDIF update statements from the command-line, see the
"Creating Directory Entries" chapter in the
Directory Server Administrator's Guide.
Specifies that the password policy request control not be sent with the bind request.
By default, the new LDAP password policy request control is sent with bind requests.
The ldapmodify tool can parse and display information from the response control if it is returned by a server; that is, the tool will print an appropriate error or warning message when a server sends the password policy response control with an appropriate value. The criticality of the request control is set to false to ensure that all LDAPv3 servers that do not understand the control can ignore it. To suppress sending of the request control with the bind request, include
-g on the command-line.
Specifies the name of the host on which the server is running. For example:
-h cyclops
Specifies the port number that the server uses.

Chapter 6. Command-Line Utilities
Option
-w
Table 6.11. Commonly-Used ldapmodify Options
Description
Specifies the password associated with the distinguished name specified in the -D option.
For example:
-w mypassword
If a dash (-) is used as the password value, the utility prompts for the password after the command is entered. This avoids having the password on the command line.
SSL Options
Use the following command-line options to specify that ldapmodify is to use LDAP over SSL
(LDAPS) when communicating with the Directory Server. LDAPS encrypts data during transit. Also, use these options for certificate-based authentication. These options are valid only when SSL has been turned on and configured for the Directory Server. For more information on certificate-based authentication and on creating a certificate database for use with LDAP clients, see the "Managing
SSL" chapter in the Directory Server Administrator's Guide.
Ensure that the Directory Server's encrypted port is specified when using these options.
Option
-3
-I
-K
-N
Description
Specifies that hostnames should be checked in
SSL certificates.
Specifies the SSL key password file that contains the token:password pair.
Specifies the path, including the filename, of the private key database of the client. Either the absolute or relative (to the server root) path can be specified. The -K option must be used when the key database has a different name than key3.db
or when the key database is not under the same directory as the certificate database, the cert8.db file (the path for which is specified with the -P option).
Specifies the certificate name to use for certificate-based client authentication. For example:
-N Server-Cert
If this option is specified, then the -Z and -
W options are required. Also, if this option is specified, then the -D and -w options must not be specified, or certificate-based authentication will not occur, and the bind operation will use the

Specifies the absolute path, including the filename, of the certificate database of the client.
This option is used only with the -Z option. When used on a machine where an SSL-enabled web browser is configured, the path specified on this option can be pointed to the certificate database for the web browser. For example:
-P /security/cert.db
The client security files can be stored on the Directory Server in the /etc/dirsrv/ slapd-instance_name directory. In this case, the -P option calls out a path and filename similar to the following:
-P /etc/dirsrv/slapd-instance_name/clientcert.db
Specifies the token and certificate name, which is separated by a semicolon (:) for PKCS11.
Specifies the password for the certificate database identified on the -P option. For example:
-W serverpassword
Specifies that SSL is to be used for the directory request.
Specifies the Start TLS request. Use this option to make a cleartext connection into a secure one. If the server does not support Start TLS, the command does not need aborted; it will continue in cleartext.
Enforces the Start TLS request. The server must respond that the request was successful.
If the server does not support Start TLS, such as Start TLS is not enabled or the certificate information is incorrect, the command is aborted immediately.

Additional ldapmodify Options
Option
-b
Description
Causes the utility to check every attribute value to determine whether the value is a valid file reference. If the value is a valid file reference, then the content of the referenced file is used as the attribute value. This is often used for specifying a path to a file containing binary data, such as JPEG.
For example, to add a jpegPhoto attribute, specify the -b option on the ldapmodify call. In the LDIF provided to ldapmodify, include a line like the following: jpegPhoto: /tmp/photo.jpeg
260
-c
-H
-M
-n
-O
Option ldapmodify
Description ldapmodify reads the contents of the photo.jpeg
file into the jpegPhoto attribute being added to the entry.
As an alternative to the -b option, use the :<
URL specifier notation, which is simpler. For example: jpegphoto:< file:///tmp/myphoto.jpg
Although the official notation requires three ///, the use of one / is accepted.
NOTE
The :< URL specifier notation only works if LDIF statement is version 1 or later, meaning version: 1 is inserted in the LDIF file. Otherwise, the file URL is appended as the attribute value rather than the contents of the file.
For further information on the LDIF format, see the "Managing Directory Entries" chapter in the
Directory Server Administrator's Guide.
Specifies that the utility run in continuous operation mode. Errors are reported, but the utility continues with modifications. The default is to quit after reporting an error.
Lists all available ldapmodify options.
Manages smart referrals. This causes the server not to return the smart referral contained on the entry but, instead, to apply the modification request directly to the entry. Use this option to add, change, or delete a directory entry that contains a smart referral. For more information about smart referrals, see the "Configuring
Directory Databases" chapter in the Directory
Server Administrator's Guide.
Specifies that the entries are not actually to be modified but that ldapmodify is to show what it would do with the specified input.
Specifies the maximum number of referral hops to follow. For example:

6.8. ldif
ldif automatically formats LDIF files and creates base-64 encoded attribute values. Base-64 encoding makes it possible to represent binary data, such as a JPEG image, in LDIF. Base-64 encoded data is represented using a double colon (::) symbol. For example: jpegPhoto:: encoded data
In addition to binary data, other values that must be base-64 encoded can identified with other symbols, including the following:
• Any value that begins with a space.
• Any value that begins with a single colon (:).
• Any value that contains non-ASCII data, including newlines.
The ldif command-line utility will take any input and format it with the correct line continuation and appropriate attribute information. The ldif utility also senses whether the input requires base-64 encoding.

Most Directory Server-related scripts are located in the /usr/lib/dirsrv/ slapd-instance_name directory for Red Hat Enterprise Linux 5 (32-bit) (and in /usr/lib64/ dirsrv/slapd-instance_name on Red Hat Enterprise Linux 64-bit systems). A few are located in the /usr/bin directory. The exact locations are listed in
Section 7.2, “Command-Line Scripts Quick
When scripts request either a directory name or a filename, always provide the absolute path.
The scripts assume the dse.ldif file is located in the /etc/dirsrv/slapd-instance_name directory.
7.2. Command-Line Scripts Quick Reference
The following shell and Perl scripts are located in either the /usr/lib/dirsrv/ slapd-instance_name (for 32-bit Red Hat Enterprise Linux) or /usr/lib64/dirsrv/ slapd-instance_name (for 64-bit Red Hat Enterprise Linux) directory.

7.3.4. db2ldif (Exports Database Contents to LDIF)
Exports the contents of the database to LDIF. This script can be executed while the server is still running, except with the -r option. To export the replication state information, shut down the server first, then run db2ldif with -r.
For the shell scripts, the script runs the ns-slapd command-line utility with the db2ldif keyword.
Ellipses (...) indicate that multiple occurrences are allowed.
Syntax db2ldif [[ -n backendInstance ] | [ -s includeSuffix ]] [ [ -x excludeSuffix ] ] [ -r ] [ -C ] [ -u ]
[ -U ] [ -m ] [ M ] [ -a outputFile ] [ -1 ] [ -N ] [ -E ]
Options
Either the -n or the -s option must be specified. By default, the output LDIF will be stored in one file.
To specify the use of several files, use the option -M.
Option

Uses only the main database file.
Decrypts encrypted data during export. This option is used only if database encryption is enabled.
Sets minimal base-64 encoding.
Uses multiple files for storing the output LDIF, with each instance stored in instance filename
(where filename is the filename specified for -a option).
Gives the instance to be exported.
Specifies that the entry IDs are not to be included in the LDIF output. The entry IDs are necessary only if the db2ldif output is to be used as input to db2index.
Exports the information required to initialize a replica when the LDIF is imported. Using this option requires that the server be stopped first, then run the db2ldif command.
The LDIF file which is created with db2ldif can be imported using ldif2db. When it is imported, if the -r option was used, than the database is automatically initialized as a replica.
See Section 7.3.8, “ldif2db (Import)” for
information on importing an LDIF file.
Names the suffixes to be included or the subtrees to be included if -n has been used.
Requests that the unique ID is not exported.
Requests that the output LDIF is not folded.
Names the suffixes to be excluded.

Syntax db2index [[ -n backendInstance ] | [ -s includeSuffix ]] [ -t
[attributeName{:indextypes(:mathingrules)}] ] [ -T vlvAttribute ]
283
Chapter 7. Command-Line Scripts
Usage
Here are a few sample commands:
• Reindex all the database index files: db2index
• Reindex cn and givenname in the database instance userRoot: db2index -n userRoot -t cn -t givenname
• Reindex cn in the database where the root suffix is dc=example,dc=com: db2index -s "dc=example,dc=com" -t cn
Options
Option
-n backendInstance
-s includeSuffix
-t attributeName{:indextypes(:mathingrules)}
-T vlvAttributeName
Description
Gives the name of the instance to be reindexed.

Names of the attributes to be reindexed.
Optionally, this can include the index type (eq, pres , sub, approx) and a matching rule OID.
Gives the names of the VLV attributes to be reindexed. The name is the VLV index object's common name in cn=config.
Table 7.7. db2index Options
7.3.6. dbverify (Checks for Corrupt Databases)
Verifies the backend database files. If the server crashes because of a corrupted database, this command can be used to verify the integrity of the different database files to help isolate any problems.
284
ds_removal
IMPORTANT
Never run dbverify when a modify operation is in progress. This command calls the BerkeleyDB utility db_verify and does not perform any locking. This can lead to data corruption if the script is run at the same time as a modify. If that occurs, an entry will be recorded in the error log:
DB ERROR: db_verify: Page 3527: out-of-order key at entry 42
DB ERROR: db_verify: DB->verify: db/mstest2/uid.db4: DB_VERIFY_BAD: Database verification failed
Secondary index file uid.db4 in db/mstest2 is corrupted.
Please run db2index(.pl) for reindexing.
Run db2index -t uid to avoid rebuilding all of the indexes or export and reimport all of the databases using db2ldif and ldif2db.
dbverify is a shell script wrapper of verify-db.pl to set the appropriate library path.
Syntax dbverify [ -a /path/to/database_directory ]
Options
Option
-a path
Description
Gives the path to the database directory. If this option is not passed with the verify- db.pl
command, then it uses the default database directory, /var/lib/dirsrv/ slapd-instance_name/db .

7.3.7. ds_removal
The ds_removal tool removes a single instance of Directory Server. The server instance usually must be running when this script is run so that the script can bind to the instance. It is also possible to force the script to run, which may be necessary if there was an interrupted installation process or the instance is corrupted or broken so that it cannot run.
When the instance is removed, it is shutdown and all of its configuration files are removed. Certificate database files, like cert8.db and key3.db, are not removed, so the remaining instance directory is renamed removed.slapd-instance.
Syntax ds_removal [ -f ] -s instance_name -w manager_password
285
Chapter 7. Command-Line Scripts
Options
Option
-f
-s
-w
Parameter instance_name manager_password
Description
Forces the removal of the instance. This can be useful if the instance is not running but must be removed anyway.
The name of the instance to remove.
The Directory Manager password to use to bind to the instance.
7.3.8. ldif2db (Import)
Runs the ns-slapd command-line utility with the ldif2db keyword. To run this script, the server must be stopped. Ellipses indicate that multiple occurrences are allowed.
For information on the equivalent Perl script, see Section 7.4.7, “ldif2db.pl (Import)” .
NOTE ldif2db supports LDIF version 1 specifications. An attribute can also be loaded using the :< URL specifier notation; for example: jpegphoto:< file:///tmp/myphoto.jpg
Although the official notation requires three ///, the use of one / is accepted. For further information on the LDIF format, see the "Managing Directory Entries" chapter in the Red Hat Directory Server Administrator's Guide.
Syntax ldif2db [[ -n backendInstance ] | [ [ -s includeSuffix ] ...]] [ -x excludeSuffix ] [ [ -i ldifFile ] ] [ -O ] [ -g string ] [ -G namespaceId ] [ -E ]
Options
Option
-c
-E
-g string
Description
Merges chunk size.
Encrypts data during import. This option is used only if database encryption is enabled.
Generates a unique ID. Type none for no unique
ID to be generated and deterministic for the generated unique ID to be name-based.
286
ldif2ldap (Performs Import Operation over LDAP)
Option
-G namespaceId
-i ldifFile
-n backendInstance
-O
-s includeSuffix
-x excludeSuffix
Table 7.9. ldif2db Options
Description
By default, a time-based unique ID is generated.
When using the deterministic generation to have a name-based unique ID, it is also possible to specify the namespace for the server to use, as follows:
-g deterministic namespace_id
namespace_id is a string of characters in the format 00-xxxxxxxx-xxxxxxxx-xxxxxxxx- xxxxxxxx .
Use this option to import the same LDIF file into two different Directory Servers and the contents of both directories should have the same set of unique IDs. If unique IDs already exist in the
LDIF file being imported, then the existing IDs are imported to the server, regardless of the options specified.
Generates a namespace ID as a name-based unique ID. This is the same as specifying the -g deterministic option.
Gives the names of the input LDIF files. When multiple files are imported, they are imported in the order they are specified on the command line.
Gives the instance to be imported. Ensure that the specified instance corresponds to the suffix contained by the LDIF file; otherwise, the data contained by the database is deleted, and the import fails.
Requests that only the core database is created, without attribute indexes.
Gives the suffixes to be included or to specify the subtrees to be included if -n has been used.
Gives the suffixes to be excluded.
7.3.9. ldif2ldap (Performs Import Operation over LDAP)
Performs an import operation over LDAP to the Directory Server. To run this script, the server must be running.
Syntax ldif2ldap [ -D rootdn ] [ -w password ] [ -f filename ]
287
Chapter 7. Command-Line Scripts
Options
Option
-D rootdn
-f filename
Description
Gives a user DN with root permissions, such as
Directory Manager.
Gives the name of the file to be imported. When importing multiple files, the files are imported in the order they are specified on the command line.
Gives the password associated with the user DN.
-w password

.
Specifies the initial replication supplier's port.
The default value is 389.
If specified, causes the routine to be entered without printing the HTML header information.
This is suitable when making multiple calls to this routine — such as specifying multiple, different, unrelated supplier servers — and expecting a single HTML output.
Specifies the refresh interval in seconds. The default value is 300 seconds. This option must be used with the -u option.
Specifies the refresh URL. The output HTML file may invoke a CGI program periodically. If this
CGI program in turn calls this script, the effect is that the output HTML file would automatically refresh itself. This is useful for continuous monitoring. See also the -t option. The script has been integrated into Red Hat Administration
Express, so that the replication status can be monitored through a web browser.
Prints the version of this script.
-v
Table 7.11. repl-monitor Options
Configuration File Format
The configuration file defines the following:
• The connection parameters for connecting to the LDAP servers to get replication information; specifying this information is mandatory.
• The server alias for more readable server names; specifying this information is optional.
• The color thresholds for time lags; specifying this information is optional.
The format for the configuration file is shown below.
[connection] host:port:binddn:bindpwd:bindcert host:port:binddn:bindpwd:bindcert
...
[alias] alias = host:port alias = host:port
...
[color] lowmark = color
289
Chapter 7. Command-Line Scripts lowmark = color
The connection section defines how this tool may connect to each LDAP server in the replication topology to get the replication-agreement information. The default binddn is cn=Directory
Manager . Simple bind will be used unless bindcert is specified with the path of a certificate database.
A server may have a dedicated or shared entry in the connection section. The script will find out the most matched entry for a given server. For example, if all the LDAP servers except host1 share the same binddn and bindpassword, the connection section will need to contain just two entries:
[connection]
*:*:binddn:bindpassword: host1:*:binddn1:bindpassword1:
In the optional alias section, use aliases such as Supplier1, Supplier2, and Hub1, to identify the servers in the replication topology. If used, the output shows these aliases, instead of http(s):// hostname:port.
The CSN time lags between suppliers and consumers can be displayed in different colors based on their range. The default color set is green for 0-5 minutes lag, yellow for 5-60 minutes lag, and pink for a lag of 60 minutes or more.
The connection parameters for all the servers in a replication topology must be specified within one configuration file. One configuration file, however, may contain information for multiple replication topologies.
Because of the connection parameters, the replication monitoring tool does not need to perform DES decryption of the credentials stored in the Directory Server. Each line in this file could either be a comment started with the # character or a connection entry of the format: host:port:binddn:bindpwd:bindcert
• host, port, and binddn can be replaced with relevant values or *, or omitted altogether. If host is null or *, the entry may apply to any host that does not have a dedicated entry in the file. If port is null or
* , the port will default to the port stored in the current replication agreement. If binddn is null or *, it defaults to cn=Directory Manager.
• bindcert can be replaced with the full path to the certificate database, null, or *. If bindcert is omitted or replaced with *, the connection will be a simple bind.
For example, the configuration file may appear as follows:
#Configuration File for Monitoring Replication Via Admin Express
[connection]
*:*:*:mypassword
[alias]
M1 = host1.example.com:10011
C1 = host4.example.com:10021
C2 = host2.example.com:10022
[color]
0 = #ccffcc
5 = #FFFFCC
290
pwdhash (Prints Encrypted Passwords)
60 = #FFCCCC
A shadow port can be set in the replication monitor configuration file. For example:
host:port=shadowport:binddn:bindpwd:bindcert
When the replication monitor finds a replication agreement that uses the specified port, it will use the shadow port to connect to retrieve statistics.
7.3.12. pwdhash (Prints Encrypted Passwords)
Prints the encrypted form of a password using one of the server's encryption algorithms. If a user cannot log in, use this script to compare the user's password to the password stored in the directory.
Syntax pwdhash [ -D config_directory ] [ -H ] [[ -s scheme ] | [ -c comparepwd ]] [ password ]

7.4.8. logconv.pl (Log Converter)
Analyzes the access logs of a Directory Server to extract usage statistics and count the occurrences of significant events. It is compatible with log formats from previous releases of Directory Server. For information on access logs, see
Section 5.1, “Access Log Reference”
.
NOTE logconv.pl
is in the /usr/bin directory.
The tool will extract the following information from access logs:
• Number of restarts
• Total number of connections
• Total operations requested
• Total results returned
• Results to requests ratio
• Number of searches
• Number of modifications
• Number of adds
• Number of deletes
• Number of modified RDNs
• Persistent searches
• Internal operations (with verbose logs)
• Entry operations (with verbose logs)
• Extended operations
• Abandoned requests
• Smart referrals received (verbose logs)
• VLV (virtual list view) operations
• VLV unindexed searches
• Server-side sorting operations
• SSL connections
• Performance lowering operations:
• Entire database searches
• Unindexed searches (details optional)
Table 7.25. Information Extracted from Access Logs
• FDs (file descriptors) taken
• FDs returned
• Highest FD taken
• Disruptions:
• Broken pipes
• Connections reset by peer
• Unavailable resources (and detail)
• Total binds and types of binds
• Most frequent occurrence lists (optional)
• Error and return codes
• Failed logins
• Connection codes
• Client IP addresses and connection codes
• Bind DNs
• Base DNs for searching
• Search filters
• Etimes (elapsed operation time)
• Longest etimes
• Nentries (number of entries in result)
• Largest Nentries
• Extended operations
• Most requested attributes
• Recommendations (optional)
The logconv.pl tool displays two types of statistics useful for monitoring and optimizing directory usage:
• Simple counts of events such as the total number of binds and the total number of searches provide overall usage information. This is the basic information that the tool will always print.
302
logconv.pl (Log Converter)
• Lists of the most frequently occurring parameters in LDAP requests provide insight into how the directory information is being accessed. For example, lists of the top ten bind DNs, base DNs, filter strings, and attributes returned can help administrators optimize the directory for its users. These lists are optional because they are computation intensive: specify only the command-line options
Some information that is extracted by the logconv.pl script is available only in logs from current releases of Directory Server; the corresponding values will be zero when analyzing logs from older versions. In addition, some information will only be present in the logs if verbose logging is enabled in
The following issues will affect the output and performance of this tool:
• Some data extracted from logs depend on connection and operation numbers that are reset and no longer unique after a server restarts. Therefore, to obtain the most accurate counts, the logs to be analyzed should not span the restart of the Directory Server.
• Due to changes in access log format in current releases of Directory Server that affected operation numbers, the tool will be more accurate logs from current versions when processing large amounts of access logs.
• For performance reasons, it is not recommended to run more than one gigabyte of access logs through the script at any one time.

Enables verbose output. With this option, logconv.pl
will compute and display all of the
optional lists described in Table 7.27, “logconv.pl
Options to Display Occurrences”
Specifies the IP address of a client to exclude from the statistics. This client will not appear in lists of IP addresses (the i flag), and the connection codes it generates will not be tallied in the total connections (default statistic) nor in the connection code details (the c flag).
For example, an administrator may want the server to ignore the effect of a load balancer that connects to the Directory Server at regular intervals. This option may be repeated to exclude multiple IP addresses.
The name of a file that contains the access log of the Directory Server. Wildcards can be used in the filename. It is also possible to specify multiple filenames. However, the statistics are computed over the set of all logs, so all logs should pertain to the same Directory
Server. The tool ignores any file with the name access.rotationinfo
.

7.4.15. register-ds-admin.pl
The register-ds-admin.pl script can be used for two things:
• Registering an existing Directory Server instance with a different Administration Server or
Configuration Directory Server.
• Creating a new, local Administration Server when only a Directory Server was installed previously.
IMPORTANT
The register-ds-admin.pl script does not support external LDAP URLs, so the
Directory Server instance must be registered against a local Administration Server.
Syntax register-ds-admin.pl.pl
[ --debug ] [ --log=name ]
Options
Option
--debug
Alternate Options
-d[dddd]
--logfile name -l
Description
This parameter turns on debugging information. For the
-d flag, increasing the number of d's increases the debug level.
This parameter specifies a log file to which to write the output. If this is not set, then the setup information is written to a temporary file. To not use a log file, set the file name to / dev/null .
7.4.16. remove-ds.pl
The remove-ds.pl script removes a single instance of Directory Server. The server instance usually must be running when this script is run so that the script can bind to the instance. It is also possible to force the script to run, which may be necessary if there was an interrupted installation process or the instance is corrupted or broken so that it cannot run.
313
Chapter 7. Command-Line Scripts
When the instance is removed, it is shutdown and all of its configuration files are removed. Certificate database files, like cert8.db and key3.db, are not removed, so the remaining instance directory is renamed removed.slapd-instance.
Syntax remove-ds.pl

-u refreshUrl
Description
If specified, causes the routine to be entered without printing the HTML header information.
This is suitable when making multiple calls to this routine — such as specifying multiple, different, unrelated supplier servers — and expecting a single HTML output.
Specifies the refresh interval in seconds. The default value is 300 seconds. This option must be used with the -u option.
Specifies the refresh URL. The output HTML file may invoke a CGI program periodically. If this
CGI program in turn calls this script, the effect is that the output HTML file would automatically refresh itself. This is useful for continuous monitoring. See also the -t option. The script has been integrated into Red Hat Administration
Express, so that the replication status can be monitored through a web browser.
Prints the version of this script.
-v
Table 7.32. repl-monitor.pl Options
Configuration File Format
The configuration file defines the following:
• The connection parameters for connecting to the LDAP servers to get replication information; specifying this information is mandatory.
• The server alias for more readable server names; specifying this information is optional.
• The color thresholds for time lags; specifying this information is optional.
The format for the configuration file is shown below.
[connection] host:port:binddn:bindpwd:bindcert host:port:binddn:bindpwd:bindcert
...
[alias] alias = host:port alias = host:port
...
[color] lowmark = color lowmark = color
The connection section defines how this tool may connect to each LDAP server in the replication topology to get the replication-agreement information. The default binddn is cn=Directory
Manager . Simple bind will be used unless bindcert is specified with the path of a certificate database.
315
Chapter 7. Command-Line Scripts
A server may have a dedicated or shared entry in the connection section. The script will find out the most matched entry for a given server. For example, if all the LDAP servers except host1 share the same binddn and bindpassword, the connection section will need to contain just two entries:
[connection]
*:*:binddn:bindpassword: host1:*:binddn1:bindpassword1:
In the optional alias section, use aliases such as Supplier1, Supplier2, and Hub1, to identify the servers in the replication topology. If used, the output shows these aliases, instead of http(s):// hostname:port.
The CSN time lags between suppliers and consumers can be displayed in different colors based on their range. The default color set is green for 0-5 minutes lag, yellow for 5-60 minutes lag, and pink for a lag of 60 minutes or more.
The connection parameters for all the servers in a replication topology must be specified within one configuration file. One configuration file, however, may contain information for multiple replication topologies.
Because of the connection parameters, the replication monitoring tool does not need to perform DES decryption of the credentials stored in the Directory Server. Each line in this file could either be a comment started with the # character or a connection entry of the following format:
host:port:binddn:bindpwd:bindcert
• host, port, and binddn can be replaced with relevant values or *, or omitted altogether. If host is null or *, the entry may apply to any host that does not have a dedicated entry in the file. If port is null or
* , the port will default to the port stored in the current replication agreement. If binddn is null or *, it defaults to cn=Directory Manager.
• bindcert can be replaced with the full path to the certificate database, null, or *. If bindcert is omitted or replaced with *, the connection will be a simple bind.
For example, the configuration file may appear as follows:
#Configuration File for Monitoring Replication Via Admin Express
[connection]
*:*:*:mypassword
[alias]
M1 = host1.example.com:10011
C1 = host4.example.com:10021
C2 = host2.example.com:10022
[color]
0 = #ccffcc
5 = #FFFFCC
60 = #FFCCCC
A shadow port can be set in the replication monitor configuration file. For example:
host:port=shadowport:binddn:bindpwd:bindcert
316
schema-reload.pl (Reload Schema Files Dynamically)
When the replication monitor finds a replication agreement that uses the specified port, it will use the shadow port to connect to retrieve statistics.
7.4.18. schema-reload.pl (Reload Schema Files Dynamically)
Manually reloads the schema files used by the Red Hat Directory Server instance either in the default location or in user-specified locations.
To run this script, the server must be running. The script creates an entry in the directory that launches this dynamic task.

Appendix A. Using the ns-slapd
Command-Line Utilities
Chapter 7, Command-Line Scripts
discussed the scripts for performing routine administration tasks on the Red Hat Directory Server (Directory Server). This appendix discusses the ns-slapd commandline utilities that can be used to perform the same tasks.
The ns-slapd command-line utilities all perform server administration tasks, and, while it can be argued that they allow a greater degree of flexibility for users, Red Hat recommends using the command-line scripts described in
Chapter 7, Command-Line Scripts
A.1. Overview of ns-slapd
ns-slapd is used to start the Directory Server process, to build a directory database from an LDIF file, or to convert an existing database to an LDIF file. For more information on starting and stopping the Directory Server, importing from LDIF using the command-line, and exporting to LDIF using the command-line, refer to the "Populating Directory Databases" chapter in the Red Hat Directory Server
Administrator's Guide.
A.2. Finding and Executing the ns-slapd Command-Line
Utilities
The ns-slapd command-line utilities are stored in /etc/dirsrv/slapd-instance_name
NOTE
In order to execute the command-line utilities, set the library paths set in the command-line scripts.
A.3. Utilities for Exporting Databases: db2ldif
Exports the contents of the database to LDIF.

Decrypts an encrypted database during export.
This option is used only if database encryption is enabled.
Sets minimal base-64 encoding.
Uses several files to store the output LDIF, with each instance stored in instance filename, where
filename is the filename specified in option -a.
Specifies the name of the backend instance to be exported.
Specifies that entry IDs are not to be included in the LDIF output. The entry IDs are necessary only if the db2ldif output is to be used as input to db2index.
Exports replication state information. The server
must be shut down before exporting using this option.
Specifies the suffix or suffixes to include in the export. There can be multiple -s arguments.
Specifies that the unique ID will not be included in the LDIF output. By default, the server includes the unique ID for all entries with a unique ID in the exported LDIF file. Only use this option to use the exported LDIF to initialize a 4.x
consumer server; otherwise, this option does not cause the server to create a unique ID for entries but simply takes what already exists in the database.
Outputs the contents of the database without wrapping lines.
Specifies a suffix or suffixes to exclude in the export. There can be multiple -x arguments.
If neither -s or -x is not specified, the server exports all suffixes within the database. When using both -x and -s options with the same suffix, the -x operation takes precedence.
Exclusion always takes precedence over inclusion. If the LDIF file will be imported into

Generates a unique ID. Type none for no unique
ID to be generated and deterministic for the generated unique ID to be name-based. By default, a time-based unique ID is generated.
When using the deterministic generation to have a name-based unique ID, it is also possible to specify the namespace for the server to use, as follows:
-g deterministic namespaceId
namespaceId is a string of characters in the format 00-xxxxxxxx-xxxxxxxx-xxxxxxxx- xxxxxxxx .

Description
Use this option to import the same LDIF file into two different Directory Servers and the contents of both directories should have the same set of unique IDs. If unique IDs already exist in the
LDIF file being imported, then the existing IDs are imported to the server, regardless of the options specified.
Specifies the LDIF file to be imported. This option is required. There can be multiple -i arguments to import more than one LDIF file at a time. When importing multiple files, the server imports the LDIF files in the order they are specified on the command line.
Specifies the name of the backend to be imported.
Specifies that no attribute indexes are created for the imported database. If this option is specified and the indexes need to be restored later, the indexes have to be recreated by hand. See the
Directory Server Administrator's Guide for further information.
Specifies the suffix or suffixes within the LDIF file to import.
Specifies suffixes within the LDIF file to exclude during the import. There can be multiple -x arguments. This option can selectively import portions of the LDIF file. If both -x and -s are used with the same suffix, -x takes precedence.
Exclusion always takes precedence over inclusion. If -x or -s are not specified, then all available suffixes will be imported from the LDIF file. To import the LDIF file into the configuration directory, do not exclude o=NetscapeRoot.
