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 new TAI interface, so named as both use WebSphere Application Server trust association interceptors (TAIs). With TAI, the end-user name is extracted from the HTTP header and forwarded to embedded Tivoli Access Manager where it is used to construct the client credential information and authorize the user. The difference with the new TAI interface is that all user credential information is available in the HTTP header (not just user name). The new TAI is the more efficient of the two solutions as an Lightweight Directory Access Protocol (LDAP) call is not required as it is with TAI. TAI functionality is retained for backwards compatibility.
