Single signon using WebSEAL or the Tivoli Access Manager plug-in for Web servers

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 signon (SSO) capability to WebSphere Application Server resources. With such an architecture, either WebSEAL or the plug-in authenticates users and forwards the collected credentials to WebSphere Application Server in the form of an IV Header. Two types of single signon 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 signon to WebSphere Application Server using either WebSEAL or the plug-in for Web servers. These tasks assume that embedded Tivoli Access Manager is configured for use.
  1. Creating a trusted user account in Tivoli Access Manager
  2. Configuring WebSEAL for use with WebSphere Application Server or Configuring Tivoli Access Manager plug-in for Web servers for use with WebSphere Application Server
  3. Configuring single signon using the trust association interceptor or Configuring single signon using trust association interceptor ++
