Configuring single sign-on capability with Tivoli Access Manager or WebSEAL

Use the following information to enable single sign-on to WAS using either WebSEAL or the plug-in for Web servers.

 

About this task

Either Tivoli Access Manager WebSEAL or Tivoli Access Manager plug-in for Web servers can be used as reverse proxy servers to provide access management and single sign-on (SSO) capability to WAS resources. With such an architecture, either WebSEAL or the plug-in authenticates users and forwards the collected credentials to WAS in the form of an IV Header. Two types of single sign-on are available, the TAI interface and the TAI++ interface, so named as both use WebSphere Application Server trust association interceptors (TAI). With the TAI, the end-user name is extracted from the HTTP header and forwarded to embedded Tivoli Access Manager where the end-user name is used to construct the client credential information and authorize the user. With the TAI++, all of the user credential information is available in the HTTP header and not just the user name. The TAI++ is the more efficient of the two solutions because a Lightweight Directory Access Protocol (LDAP) call is not required. TAI functionality is retained for backwards compatibility.

Complete the following tasks to enable single sign-on to WAS using either WebSEAL or the plug-in for Web servers. These tasks assume that embedded Tivoli Access Manager is configured for use.

 

Procedure

  1. Create a trusted user account for Tivoli Access Manager in the shared LDAP user registry. For more information, see Creating a trusted user account in Tivoli Access Manager .

  2. Configure either WebSEAL or the Tivoli Access Manager plug-in for Web servers to work with WebSphere Application Server. For more information, see either of the following articles:

  3. Configure single sign-on using either the TAI or TAI++ interface. For more information, see either of the following articles:
