DIGIPASS Authentication for Citrix Web Interface Overview
2.1
General Overview
2.1.1
Overview of the DIGIPASS Authentication Plug-In without Citrix SmartAccess Integration
The DIGIPASS Authentication Plug-In is an add-on for Internet Information Services (IIS) and can be
configured to intercept authentication requests to Web sites using the HTTP forms authentication mechanism.
It allows users to use one-time passwords (OTPs) instead of static passwords. The plug-in intercepts
authentication requests, validates the OTP, and replaces it with the static password expected by the back-end.
The OTPs are validated using an IDENTIKEY Server or aXsGUARD Identifier.
The DIGIPASS Authentication Plug-In is a native module for IIS 7.x.
Figure 1: DIGIPASS Authentication for Citrix Web Interface Overview
2.1.2
Overview of the DIGIPASS Authentication Plug-In with Citrix SmartAccess Integration
Citrix SmartAccess allows users to control access to available applications on computers running Citrix servers
through Access Gateway Enterprise policies and filters. SmartAccess permits the use of endpoint analysis as a
condition for application access, along with other factors.

12
DIGIPASS Authentication for Citrix Web Interface User Manual
DIGIPASS Authentication for Citrix Web Interface Overview
Citrix SmartAccess integrates Access Gateway Enterprise components with the Web Interface for Citrix and
Citrix Presentation Server or Citrix XenApp. Refer to Section 3.1.2 Recommended Citrix SmartAccess Setup for
SmartAccess setup recommendations.
The authentication process is similar to environments that do not use Citrix SmartAccess. Authentication
requests are intercepted so that users can authenticate with one-time passwords (OTPs) instead of their static
passwords. Because user credentials are passed on as HTTP headers, you need to configure DIGIPASS
Authentication for Citrix Web Interface HTTP header filtering. With this enabled, OTPs are extracted from the
HTTP header fields, validated, and replaced with the corresponding static password. For instructions to
configure authentication for Citrix SmartAccess, refer to Section 4.1.3 Configuring DIGIPASS Authentication for
Citrix Web Interface HTTP Header Filtering.
Citrix SmartAccess does not support the HTTP forms mechanism. Consequently, if you use the DIGIPASS
Authentication Plug-In in a SmartAccess environment, you will be unable to utilize DIGIPASS Authentication
for Citrix Web Interface features such as challenge/response login or password change.

2.2
DIGIPASS Authentication for Citrix Web Interface Overview
DIGIPASS Authentication Plug-In 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 DIGIPASS Authentication Plug-In
sends authentication requests. This component is:
•
For IDENTIKEY Server, the IDENTIKEY Server service or daemon
•
For aXsGUARD Identifier, the IDENTIKEY Server daemon
Client record
The client record is the record defined in the authentication server's data store, to represent an installed
instance of the DIGIPASS Authentication Plug-In.
It is 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 DIGIPASS Authentication Plug-In
Forms authentication
The method of authentication where a Web site provides its own login page.
NOTE
Citrix SmartAccess does not support forms authentication.
HTTP header filtering
A method of authentication that is required when using the DIGIPASS Authentication Plug-In in Citrix
SmartAccess environments.
DIGIPASS Authentication Plug-In
General term for a plug-in to IIS to allow DIGIPASS authentication to take place.

DIGIPASS Authentication for Citrix Web Interface User Manual
2.3
DIGIPASS Authentication for Citrix Web Interface Overview
Authentication Methods
See the Product Guide for the authentication server for detailed information on login methods and options.
Response-only login
Users log in via the current login page with their user name and a one-time password (OTP).
One-step challenge/response login
A random challenge - of a length configured for all users in the authentication server’s policy - is displayed on
the login page. Users log in with their user name and DIGIPASS response to the displayed challenge.
This requires modification of the current login page used by Citrix Web Interface. For more information, refer to
Section 5.2 Setting Up the One-Step Challenge/Response Login Page.
NOTE
Citrix SmartAccess does not support one-step challenge/response login.
Two-step challenge/response login
After the login page, the DIGIPASS Authentication Plug-In redirects users to a ‘Challenge page’ where a
random challenge – of the length required by the user’s DIGIPASS – 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. For more information, refer
to Section 5.5 Creating a Two-Step Challenge/Response Template.
NOTE
Citrix SmartAccess does not support two-step challenge/response login.
Virtual DIGIPASS login
The Virtual DIGIPASS login process varies depending on whether the DIGIPASS Authentication Plug-In is
integrated into a Citrix SmartAccess environment.
•
Without Citrix SmartAccess
Users logging in with a Virtual DIGIPASS use a similar process to the two-step challenge/response login. If
the user has a primary Virtual DIGIPASS assigned, or requests use of the backup Virtual DIGIPASS 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 DIGIPASS Authentication Plug-In to the challenge page to enter the OTP.

15
DIGIPASS Authentication for Citrix Web Interface User Manual
DIGIPASS Authentication for Citrix Web Interface Overview
This uses the same challenge template used in the two-step challenge/response login.
•
With Citrix SmartAccess
In this environment, users logging in with a Virtual DIGIPASS also need to use a two-step process. They
attempt a login with their user ID, password and/or a keyword. The login fails, and triggers the sending of
a one-time password to the user’s mobile via text message. The user needs to click the browser’s Back
button to return to the login page and re-attempt a login, using their password and OTP.

2.4
DIGIPASS Authentication for Citrix Web Interface Overview
Server Connection Management
The DIGIPASS Authentication Plug-In provides flexibility in managing connections to multiple primary
and/or backup authentication servers. This allows redundancy and load sharing over multiple servers.
2.4.1
Connection Profiles
Two connection profiles are available:
Primary
The server(s) to which the DIGIPASS Authentication Plug-In will first attempt to connect, using a roundrobin scheme.
Backup
Backup servers will be used if load sharing is enabled and the primary server(s) are busy.
2.4.2
Connection Options
Maximum connections
The maximum number of connections that the DIGIPASS Authentication Plug-In may have open to the
authentication server at one time.
Timeout
The time that the DIGIPASS Authentication Plug-In should wait for a reply from the authentication server.
Reconnect interval
If the DIGIPASS Authentication Plug-In cannot connect to an authentication server, it will make another
connection attempt to this server only after a time period defined by the reconnect interval. If other servers are
configured, connection attempts to these servers are made in the meantime.

DIGIPASS Authentication for Citrix Web Interface Overview
Tracing
The DIGIPASS Authentication Plug-In allows use of a trace file to record plug-in activity, e.g. for
troubleshooting. This will include errors that have been encountered, warnings, and general information about
performed authentication requests.
The level of tracing that the DIGIPASS Authentication Plug-In 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:
•
Error messages
•
Warnings
•
High-level information about plug-in activity
Full tracing includes:
•
Error messages
•
Warnings
•
High-level information about plug-in activity
•
Detailed information about plug-in activity
NOTE
The DIGIPASS Authentication Plug-In will require permissions for the directory in which the
tracing file is kept. See Section 6.1.2 Checking Permissions for more information.

Installing DIGIPASS Authentication for Citrix Web Interface
Pre-Installation Tasks
Before installing the DIGIPASS Authentication Plug-In, there are several tasks which need to be completed.
Performing these tasks (where applicable) will assist in a quick, smooth installation process.
3.2.1
Installing the Authentication Server
An authentication server should be installed on the network before the DIGIPASS Authentication Plug-In is
installed. See Section 3.1 System Requirements for compatible servers and Section 4.4 Configuring the
Authentication Server for configuration recommendations.
CAUTION
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 aXsGUARD 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.
3.2.2
IIS and Citrix
Ensure IIS and the Citrix environment are installed and working correctly. The DIGIPASS Authentication
Plug-In needs to be installed on the computer where Citrix Web Interface, Citrix Presentation Server/XenApp,
and IIS are running.
3.2.3
Information Needed
Before you begin installation of the DIGIPASS Authentication Plug-In, 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 SEAL 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).

3.2.4
Installing DIGIPASS Authentication for Citrix Web Interface
Licensing
The authentication server will associate authentication requests from each incoming IP address with a different
client record. Your DIGIPASS Authentication Plug-In license will be tied to that IP address. The IP address
of the computer where IIS is running must match the IP address of the license, or authentication will not be
possible.

Editing the Configuration File
The DIGIPASS Authentication Plug-In Configuration Center writes to an XML file named Settings.xml in
the installation directory. It is possible to edit this file directly instead of using the Configuration Center.
NOTE
This option is recommended only for advanced users. The DIGIPASS Authentication Plug-In
Configuration Center 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 DIGIPASS Authentication Plug-In to stop working.
If Settings.xml is damaged, uses incorrect XML syntax, etc., the DIGIPASS Authentication PlugIn will attempt to operate with default values, with logging enabled (including the problems with
Settings.xml).

4.4
Configuring the Authentication Server
4.4.1
Client Record
Configuring the DIGIPASS Authentication Plug-In
A client record must be configured in the authentication server for the DIGIPASS Authentication Plug-In.
The configuration wizard can create the required record if a connection to the authentication server and an
administrator account with sufficient privileges are available. If the configuration wizard does not create a
client 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 the
DIGIPASS Authentication Plug-In Configuration Center.
•
Select a policy for the authentication server to use when processing authentication requests from the
DIGIPASS Authentication Plug-In.
A valid license key must be obtained for the DIGIPASS Authentication Plug-In and loaded in to the client
record.
4.4.2
Configuring for Windows User Accounts
4.4.2.1
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 DIGIPASS user account has been created.

58
DIGIPASS Authentication for Citrix Web Interface User Manual
4.4.2.2
Configuring the DIGIPASS Authentication Plug-In
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 configuration steps. The embedded PostgreSQL database is set to convert to lower case by default. See
the Encoding and Case Sensitivity section in the IDENTIKEY Server Administrator Guide for more information.
4.4.2.3
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 7 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 DIGIPASS Authentication Plug-In.
4.4.3
Policy
The client record created during installation of the DIGIPASS Authentication Plug-In uses the default
password replacement policy for the package. It will be named:
•
IDENTIKEY Windows Password Replacement (IDENTIKEY Server)
•
IDENTIKEY Microsoft AD Password Replacement (aXsGUARD Identifier)
This policy is configured with the following settings:
•
Back-end authentication is set to Always (used for dynamic user registration, password autolearn,
etc. Not all logins).
•
Windows is used as the back-end authenticator in the IDENTIKEY Windows Password Replacement policy.
•
Dynamic user registration, password autolearn and stored password proxy are enabled.

59
DIGIPASS Authentication for Citrix Web Interface User Manual
•
Configuring the DIGIPASS Authentication Plug-In
Group check mode is set to Pass Back and DIGIPASS Users is placed in the Group list. This will mean
that any logins by users not in the DIGIPASS users group will be ignored – not rejected – by the
authentication server in the IDENTIKEY Windows Password Replacement policy.
If you need different settings, either select a different policy (e.g. Self-Assignment or Auto-Assignment) for the
DIGIPASS Authentication Plug-In component or copy the password replacement policy to a new record,
modify the new policy as required, and use the new policy for the DIGIPASS Authentication Plug-In
component.
4.4.3.1
DIGIPASS users log in 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) or Microsoft AD (aXsGUARD Identifier)
These settings allow the authentication server to check user login details with Active Directory in case of DUR,
password autolearn and Self-Assignment logins through the DIGIPASS Authentication Plug-In.
DIGIPASS 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 DIGIPASS Authentication Plug-In in place of the one-time
password entered by the user on future logins.
DIGIPASS 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 DIGIPASS/Password, meaning that users usually need to
use an OTP when logging in, but are not required to in some circumstances (e.g. in grace period).
4.4.3.2
DIGIPASS users log in with password and OTP (Windows user accounts)
The following settings are recommended for this scenario:

case of DUR and Self-Assignment logins through the DIGIPASS Authentication Plug-In.
DIGIPASS 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 Active Directory password.
DIGIPASS 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 DIGIPASS/Password, meaning that users usually need to
use an OTP when logging in, but are not required to in some circumstances (e.g. in grace period).
4.4.3.3
Local authentication only
These settings are typically used where:
•
The authentication server does not check authentication details against Windows accounts.
Back-end authentication
•
Back-end authentication: none
The authentication server will not check user login details with Active Directory.
DIGIPASS user account handling
•
Dynamic user registration: disabled
•
Password autolearn: disabled
•
Stored password proxy: disabled
New DIGIPASS user accounts must be created manually (no DUR). An Active Directory password is not stored,
because back-end authentication is disabled.

Displaying the Login Failure Reason
The DIGIPASS Authentication Plug-In 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 DIGIPASS Authentication Plug-In
will pass the error or status code and message text for the authentication server to Citrix, which may then
display the message verbatim or interpret the code to provide the user with a clear explanation or set of
instructions.
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.

Frequently asked questions

It's a plug-in for Internet Information Services (IIS) that allows users to authenticate to Citrix Web Interface using one-time passwords (OTPs) instead of their static passwords
The plug-in intercepts authentication requests, validates the OTP, and replaces it with the static password expected by the back-end. The OTPs are validated using an IDENTIKEY Server or aXsGUARD Identifier.
The system requirements are listed in the document. They include software requirements such as the operating system, IIS version, and other software components. It also mentions recommended Citrix SmartAccess setup.
The pre-installation tasks involve installing the authentication server like IDENTIKEY Server or aXsGUARD Identifier, configuring IIS and Citrix, gathering necessary information, and licensing.
The manual mentions several authentication methods, including response-only login, one-step challenge/response login, two-step challenge/response login, and Virtual DIGIPASS login.
