DIGIPASS Authentication for Citrix Web Interface Overview
1
DIGIPASS Authentication for Citrix Web Interface
Overview
The main component of DIGIPASS Authentication for Citrix Web Interface is the IIS Module.
1.1
IIS Module Overview
The IIS Module is an add-on for VACMAN Middleware, IDENTIKEY Server and aXsGUARD Identifier. It can be
configured to intercept authentication requests to a website which uses a login form and redirect them to an
Authentication Server. The Authentication Server must be one of the following servers:
IDENTIKEY Server 3.1or higher – IDENTIKEY Server component
VACMAN Middleware 3.0 – Authentication Server component
aXsGUARD Identifier 3.1.3.x or higher
The IIS Module is an ISAPI extension specifically designed for use with IIS 6, although IIS 7 or IIS 7.5 can be used
if the Backwards Compatibility module is installed.
Figure 1 – DIGIPASS Authentication for Citrix Overview
1.1.1
Authentication Methods
See the Product Guide for the authentication server for detailed information on login methods and options.
DIGIPASS Authentication for Citrix Web Interface Guide
4
DIGIPASS Authentication for Citrix Web Interface Overview
Response Only login
Users log in via the current login page with their username and One Time Password (OTP).
1-Step Challenge/Response login
A random challenge - of a length configured for all users - is displayed on the login page. Users log in with their
username and DIGPASS response to the displayed challenge.
This requires modification of the current login page used by Citrix Web Interface.
2-Step Challenge/Response login
After the login page, the IIS Module redirects users to a ‘Challenge page’ where a random challenge – of the
length required by the user’s DIGPASS – is displayed. The user must enter a response to the challenge in order to
complete the login.
A Challenge page template must be used with this feature. A default template is provided. It can be used without
modification or it can be customized to match your preferred look and feel.
Virtual DIGIPASS login
Users logging in with a Virtual DIGPASS use a similar process to the 2-step Challenge/Response login. If the user
has a Primary Virtual DIGPASS assigned, or requests use of the Backup Virtual DIGPASS feature during the first
step, an OTP will be sent to the user’s mobile phone via text message. The user is then redirected by the IIS
Module to the Challenge page to enter the OTP.
This uses the same Challenge template used in the 2-step Challenge/Response login.
1.1.2
Server Connection Management
The IIS Module provides flexibility in managing connections to multiple primary and/or backup Authentication
Servers. This allows redundancy and load sharing over multiple Servers.
1.1.2.1
Connection Profiles
Two connection profiles are available:
Primary
The Server(s) to which the IIS Module will first attempt to connect. The Primary Authentication Server(s) take the
majority of the data load. Load sharing may be implemented over all Primary Authentication Servers.
DIGIPASS Authentication for Citrix Web Interface Guide
5
DIGIPASS Authentication for Citrix Web Interface Overview
Backup
A Backup Server can provide redundancy and failover. It is typically a local machine which, if the Primary
Authentication Server is busy or cannot be contacted, will be used until a connection to the Primary Server can be
re-established.
1.1.2.2
Connection Options
Terminology
Some of the terms used in configuring server connections are explained below:
Maximum Connections
The maximum number of connections that the IIS Module may have open to the Authentication Server at one time.
Timeout
The time that the IIS Module should wait for a reply from the Authentication Server.
Reconnect Interval
If the IIS Module cannot connect to an Authentication Server, it will make connection attempts at increasing time
intervals until it succeeds in establishing a connection. The time period between connection attempts is the
Reconnect Interval.
Figure 2 – Standard Server Connection Configuration
This setup uses one main Authentication Server to handle requests from the Web Server, with a backup
Authentication Server for use when the main Server is busy or unavailable.

DIGIPASS Authentication for Citrix Web Interface Overview
1.1.3
IIS Module Terminology
The following definitions describe how these terms are used in this document. They are also used in other IIS
Package manuals.
Authentication Server
The term Authentication Server refers to the component to which the IIS Module sends authentication requests.
This component is:
For IDENTIKEY Server, the IDENTIKEY Server service or daemon
For aXsGUARD Identifier, the IDENTIKEY Server daemon
For VACMAN Middleware 3, the DIGIPASS Authentication Service
Basic Authentication
A method of authentication that uses the HTTP Basic Authentication mechanism. This uses a login pop-up box
provided by the Browser.
Client/Component/Client Component
The above terms refer to the same thing. The Client Component is the record defined in the Authentication
Server's data store, to represent an installed instance of the IIS Module. Different terms are used due to
differences in terminology on the server side. i.e. Client for IDENTIKEY Server and aXsGUARD, Component for
VACMAN Middleware 3.
They are used for the following main purposes:
To indicate that the Authentication Server is permitted to process a request from that client
To specify a Policy to be used to process the request
To hold a License Key for the IIS Module
Forms Authentication
The method of authentication where the Web Site provides its own login page.
IIS Module
General term for a plug-in to IIS to allow DIGIPASS authentication to take place.
The IIS Module takes two forms depending on its application:
IIS Extension
The IIS Extension is an ISAPI extension used for Forms Authentication. It is referred to as the IIS Module in manuals
for Forms Authentication, unless the text is referring specifically to the IIS Extension.
DIGIPASS Authentication for Citrix Web Interface Guide
7
DIGIPASS Authentication for Citrix Web Interface Overview
IIS Filter
The IIS Filter is an ISAPI filter used for Basic Authentication. The IIS plug-in is referred to as the IIS Module in
manuals for Basic Authentication, unless the text is referring specifically to the IIS Filter.
1.1.4
Password Change
The IIS Module can capture password changes made in Citrix Web Interface. This requires modification of the
current Password Change page used by Citrix Web Interface.
1.1.5
Tracing
The IIS Module makes use of a trace file to record information about events that occur on the system, for use in
troubleshooting. This could include generic information, changing conditions, or problems and errors that have
been encountered.
The level of tracing that the IIS Module employs depends on its configuration settings.
Caution
Enabling Full Tracing should only be done for troubleshooting purposes. There are no limits set
on the size of the tracing file, so if the option is left on too long on a high-load system the file
may dramatically slow down or crash Windows, due to excessive I/O or filling up the hard drive.
Because there are no size limitations set on the trace file, it is not recommended that you have
tracing permanently enabled. If your system is set up with Tracing always enabled, ensure that
the file size does not cause problems by deleting or archiving it whenever it gets too large.
Basic tracing includes:
Critical error/warning messages [CRITC]
Major error/warning messages [MAJOR]
Minor error/warning messages [MINOR]
Configuration messages [CONFG]
Full tracing includes:
Critical error/warning messages [CRITC]
Major error/warning messages [MAJOR]
Minor error/warning messages [MINOR]
Configuration messages [CONFG]
Informational messages [INFOR]
Data tracing messages [DATA]
DIGIPASS Authentication for Citrix Web Interface Guide
8
DIGIPASS Authentication for Citrix Web Interface Overview
Debugging messages (useful for support purposes) [DEBUG]
Security messages, messages that may contain security sensitive data [SECUR]
Note
The IIS Module will require permissions for the directory in which the tracing file is kept. See
5.1.2 Check Permissions for more information.

Installation
Before installing the IIS Module, check that all system requirements and pre-installation tasks have been met. This
will help ensure a smooth, trouble-free installation and integration process.
2.1
System Requirements
2.1.1
Server Requirements - Software
An authentication server running on another machine. This should be one of the following:
IDENTIKEY Server 3.1 or higher – IDENTIKEY Server component
VACMAN Middleware 3.0 - Authentication Server component
aXsGUARD Identifier 3.1.3.x or higher
Internet Information Services (IIS) 6.0 OR Internet Information Services (IIS) 7 or 7.5 with Backward
Compatibility module installed.
The following operating systems are supported:
Windows Server 2003 SP2 or higher
Windows Server 2003 R2 standard x64Edition SP2
Windows 2008 R2 or higher
Citrix Presentation Server or XenApp containing Citrix Web Interface 4.5, 4.6, 5.0.1, 5.1.2, 5.2 or 5.3
OR
Citrix Advanced Access Control Server 4.5
The User must have administration rights on the installation machine.
2.2
Pre-Installation Tasks
Before installing the IIS Module, there are several tasks which need to be completed. Performing these tasks
(where applicable) will assist in a quick, smooth installation process.
Note
DIGIPASS Authentication for Citrix Web Interface cannot be installed on the same machine as
any other Digipass Authentication packages.
DIGIPASS Authentication for Citrix Web Interface Guide
10
Installation
2.2.1
Install Authentication Server
An Authentication Server must be installed on the network before the IIS Module is installed. See 2.1 System
Requirements for compatible servers and 3.6 Configure Authentication Server for configuration recommendations.
Warning
If the users are Active Directory users on a Windows platform, it is recommended that the Use
Windows User Name Resolution feature on the Authentication Server is enabled. This uses
Windows functions to identify User IDs as Windows User accounts, including the domain to
which the account belongs.
This feature is not available on Linux platforms or the aXs GUARD Identifier.
If the Use Windows User Name Resolution feature is disabled, it is essential that users always
use the same login name. If they try to log in using a different form of their Windows account
name, their login will be rejected, unless a second Digipass User account has been created.
2.2.2
IIS
Ensure IIS and the Citrix Web Interface are installed and working correctly. The Citrix Web Interface must be
installed on the IIS server where the web server is running.
2.2.3
Information Needed
Before you begin installation of the IIS Module, ensure that you have the following information easily accessible, as
you will need to enter this during the installation.
IP address and port number of the Authentication Server. To check this, open the Authentication Server
Configuration and check the Component location and Port fields.
Source IP address on the local machine to use when connecting to the Authentication Server (if multiple IP
addresses are configured for this machine, as this affects licensing – see below).
2.2.4
Licensing
The Authentication Server will regard each incoming IP address as a different Client Component. This is the reason
for selecting a single IP address in connecting to the Authentication Server if there is more than one IP address for
a machine.

Configuration File
The IIS Module Configuration writes to an .xml file named dpmodulecfg.xml in the installation directory. It is
possible to edit this file directly instead of using the IIS Module Configuration. Increment the Revision number by 1
to have your changes take effect.
Note
This option is recommended only for advanced users. The IIS Module Configuration GUI will
prevent most common configuration mistakes, but there are no such checks made when edits
are made directly to the configuration file. Incorrect changes to the configuration file may cause
the IIS Module to stop working.

Component Record
A Client Component record must be configured in the Authentication Server for the IIS Module. The Configuration
Wizard can create the required record if a connection to the Authentication Server, and an administrator account
with sufficient privileges, is available. If the Configuration Wizard does not create a Client Component record, this
must be done manually.
The Component Type should be set to Citrix Web Interface.
The Location should be set to the same IP address as in the Connect from IP Address setting in IIS Module
Configuration.
Select a Policy for the Authentication Server to use when processing authentication requests from the IIS
Module. See 3.6.3 Policy for more information.
A valid license key must be obtained for the IIS Module and loaded in to the Component record.
3.6.2
Configure for Windows User Accounts
3.6.2.1
Windows User Name Resolution
If the Authentication Server is installed on a Windows platform and is using an ODBC database (including the
embedded database) as its data store, it is recommended that you enable Windows User Name Resolution. This
allows the Authentication Server to use Windows functionality to resolve a User ID – as entered during a login –
into a User ID and Domain. It is highly recommended if Dynamic User Registration will be enabled.
This setting is not required where the Authentication Server is using Active Directory as its data store - name
resolution will occur automatically.
This setting is not available on IDENTIKEY Server on Linux, or aXsGUARD Identifier.
If the Use Windows User Name Resolution feature is disabled or unavailable, it is essential that users always use
the same login name. If they try to log in using a different form of their Windows account name, their login will be
rejected, unless a second DIGPASS User account has been created. This is essential for enabling the change
password facility to work.
3.6.2.2
Case Sensitivity
Windows User names are not case-sensitive. If the ODBC database used by the Authentication Server is casesensitive, ensure that User ID case is converted to lower case. Upper case may also be used, but will involve extra
DIGIPASS Authentication for Citrix Web Interface Guide
43
IIS Module Configuration
configuration steps. The embedded PostgreSQL database is set to convert to lower case by default. See the
Encoding and Case Sensitivity topic in the Administrator Reference for more information.
3.6.2.3
Default Domain
Where Users log in without entering a domain name or UPN, the Authentication Server will need to be configured to
use the correct domain. There are two basic scenarios that might apply:
Change Master Domain
If Users will only ever be logging in to one domain via the Authentication Server, the simplest solution is to set the
Master Domain name to the Fully Qualified Domain Name of the required domain.
This option is not available for aXsGUARD Identifier.
Set Default Domain in Policy
This strategy should be used if:
You wish to keep the Master Domain strictly for administration accounts and separate from User accounts
The Authentication Server may be required to handle a different default domain for different IIS 6 Modules or
other clients
Each Policy may be configured with a Default Domain, to be used if a User does not enter a domain on login.
Typically, you will need to modify the Policy used by each IIS Module.
DIGIPASS Authentication for Citrix Web Interface Guide
44
IIS Module Configuration
3.6.3
Policy
The Component record created during installation of the IIS Module uses the default Password Replacement Policy
for the package. It will be named:
VM3 Windows Password Replacement (VACMAN Middleware)
Identikey Windows Password Replacement (IDENTIKEY Server)
Identikey Microsoft AD Password Replacement (aXsGUARD Identifier)
These Policies are configured with the following settings:
Note
These settings are all available on Windows but the VM3 Windows Password Replacement
policy is not available on IDENTIKEY Server on Linux or the aXsGUARD Identifier, so the
corresponding settings are not available on those platforms
Back-End Authentication is set to If Needed (used for DUR, Password Autolearn etc, not all logins).
Windows is used as the back-end authenticator in the VM3 Windows Password Replacement and Identikey
Windows Password Replacement Policies.
Dynamic User Registration, Password Autolearn and Stored Password Proxy are enabled.
Group Check Mode is set to Pass Back and DIGPASS Users is placed in the Group List. This will mean that
any logins by Users not in the DIGPASS Users group will be ignored – not rejected – by the Authentication
Server in the VM3 Windows Password Replacement and Identikey Windows Password Replacement Policies.
If you will need different settings, either select a different Policy (eg. Self-Assignment or Auto-Assignment) for the
IIS Module Component or copy the Password Replacement Policy to a new record, modify the new Policy as
required, and use the new Policy for the IIS Module Component.
3.6.3.1
Standard Policy Configurations for Citrix Web Interface
DIGPASS Users login with OTP only (Windows user accounts)
The following settings are recommended for this scenario:
Back-End Authentication
Back-End Authentication: If Needed
Back-End Protocol: Windows (IDENTIKEY Server and VACMAN Middleware) or Microsoft AD (aXs GUARD Identifier)
These settings allow the Authentication Server to check user login details with Windows or Active Directory in case
of DUR, Password Autolearn and Self-Assignment logins through the IIS Module.
DIGIPASS Authentication for Citrix Web Interface Guide
45
IIS Module Configuration
DIGPASS User Account Handling
Dynamic User Registration: Enabled
Password Autolearn: Enabled
Stored Password Proxy: Enabled
These settings allow the Authentication Server to create an account for an unrecognized User based on a
successful Windows or Active Directory authentication. The Authentication Server can then store the User’s Active
Directory password and replay it to the IIS Module in place of the One Time Password entered by the User on future
logins.
DIGPASS Assignment Mode
Either Self-Assignment or Auto-Assignment would typically be used in this scenario, although manual assignment
may also be used.
Local Authentication
The typical setting for local authentication would be DIGPASS/Password, meaning that Users usually need to use
an OTP when logging in, but are not required to in some circumstances (eg. in Grace Period).
DIGPASS Users login with Password and OTP (Windows user accounts)
The following settings are recommended for this scenario:
Back-End Authentication
Back-End Authentication: If Needed
Back-End Protocol: Windows (IDENTIKEY Server and VACMAN Middleware) or Microsoft AD (aXsGUARD Identifier)
These settings allow the Authentication Server to check user login details with Windows or Active Directory in case
of DUR and Self-Assignment logins through the IIS Module.
DIGPASS User Account Handling
Dynamic User Registration: Enabled
Password Autolearn: Disabled
Stored Password Proxy: Disabled
These settings allow the Authentication Server to create an account for an unrecognized User based on a
successful Windows or Active Directory authentication. The Authentication Server will not store or replay a User’s
Windows or Active Directory password.

Set Up Password Change Page
The IIS Module can capture password changes within Citrix Web Interface. For version 4.x, note that only expired
password changes can be captured.
To enable this, the Password Change page used by Citrix Web Interface must be modified. A modified version of
the standard password change page is provided with the IIS Module, and is installed to &lt;install
directory&gt;\citrix\CWI_&lt;citrix version&gt;\changepassword.inc. For Citrix Web Interface 4.x an additional file –
login.aspxf (4.5 and 4.6) - must be modified.
Some file names and locations, and code used in the change password page, will vary depending on the version of
Citrix Web Interface in use. Follow the instructions for your current version of Citrix Web Interface.

Modify Custom Change Password Page
If you have a current Change Password page in use which differs from the standard Citrix page, you may need to
modify it rather than replacing it with the Change Password page provided with the IIS Module.
A piece of code must be inserted into the page to include a hidden field used by the IIS Module . The code required
can be found below or taken directly from the Change Password page added to the &lt;install
directory&gt;\citrix\CWI_&lt;Citrix version&gt; directory during installation.

Post-Installation Tasks
4.3.9
Modify Server Include File
For Citrix Web Interface 4.x only, login.aspxf (4.5 and 4.6) file for a site may have been modified from the default
Citrix file by other programs. If so, it is recommended that you modify it with the required extra code rather than
replacing it with the file included with the IIS Module.
The code should be inserted in the loginAuthenticateExplicit function, underneath the following text:
if (credentials != null &amp;&amp; !bIsError()) {
System.Collections.Hashtable parameters = new System.Collections.Hashtable();
parameters[&quot;AccessToken&quot;] = credentials;
parameters[&quot;ExplicitAuth&quot;] = expAuth;
Code
// Digipass Authentication for Citrix Web Interface modifications : START
// The following session variable is required to learn password changes.
Session[&quot;dp_user&quot;] = (string)credentials.getUserIdentity();
// Digipass Authentication for Citrix Web Interface modifications : END
4.4
Display Login Failure Reason
The IIS Module may be configured to pass information to Citrix when it fails an authentication request. This
information may be used to provide Users with an explanation of why their login failed, and steps that they may be
able to take to rectify the problem. The IIS Module will pass the error or status code and message text for the
Authentication Server to Citrix, which – depending on settings in the messagecenter.inc and login.js files - may
then display the message verbatim or interpret the code to provide the User with a clear explanation or set of
instructions.
Note
Citrix Advanced Access Control 4.5 cannot be formatted in this manner. To handle login failures
you must configure the Ctrix disallowed page for authentication failure.
4.4.1
Replace Default Files
A simple option is to replace the default Citrix Web Interface files with those provided with the Digipass Pack. This
will allow Citrix Web Interface to display an Authentication Server error or status code and message on the User’s
screen underneath the Citrix-generated login failure information.

Modify Custom Login Page
If you have a current login page in use which differs from the standard Citrix login page, you may need to modify it
rather than replacing it with the login page provided with the IIS Module.
When the IIS Module detects a request for the login page, it adds three headers to the request before passing it on.
The headers added are:
Table 5 - Headers added to login request string
Header
VASCO-Challenge
VASCO-State
VASCO-FlashCode
Explanation
Contains the string challenge to be displayed to the user. ie &quot;1234&quot;
Contains data that needs to be passed as the field &quot;DPExtState&quot; on the login request.
Contains the html code needed to include the challenge flash applet in the login page.
This requires the applet be copied to the appropriate location in the website.
A piece of code must be inserted into the login page to include 1-step Challenge/Response functionality. The code
required can be found below or taken directly from the login page added to the &lt;install

IIS Module Installation Problems
The installation program for the IIS Module will usually complete the following tasks automatically. However, if it
fails in these tasks for some reason, an error message will be displayed during installation. These steps can then
be followed to complete the installation manually.
If you are having trouble running the Authentication Server and the IIS Module for the first time, following these
steps may help you track down the problem and fix it manually.

Other Troubleshooting Options
If you are still having problems after checking that all installation and configuration settings for the IIS Module are
correct, follow these steps to check for other possible problems.
5.2.1
No Trace File
If there is no trace file, or the trace file information does not help, first check that the ISAPI extension has been
registered (see 5.1.2.4 Register IIS Module Extension for instructions) and the wildcard application mapping is set
(see 5.1.3 Register as Wildcard Application Mapping for instructions). Next, check the Windows Events for any
warnings or errors generated by a failure to load the IIS 6 Module into IIS.
5.2.2
5.2.3
Information from Trace File
1.
Set the IIS Module to tracing.
2.
Restart IIS.
3.
Attempt a login.
4.
Check the trace file for information on the start-up conditions of the IIS Module and of the login attempt.
Authentication Server
If the IIS Module appears to load and update but you are unable to achieve a successful login, check the
Authentication Server. Open the Audit Viewer to:
check available audit messages in the audit files or database.
configure a live audit connection from the Authentication Server and retry a login.
See the Authentication Server's Administrator Reference for more information.
5.2.4
Licensing
Check that the IIS Module has a valid client Component in the Authentication Server data store, which has a valid
license loaded. See the Licensing section of the Authentication Server's Administrator Reference for more
information on licensing options.
