1. A request arrives on an input channel (for example, Web or EJB).
2. The authentication data is passed through the authentication modules.
3. This flow highlights the WebSphere Application Server default trust
association interceptor (TAI) for LTPA token. LTPA is the application server’s
default and the recommended trust token implementation. Trust is asserted at
this stage of the processing. If the token is determined valid, the user
information that it contains is trusted and the identity of the user is asserted.
4. After token processing, the user credentials are
rebuilt from the information that is retrieved from the token.
5. User credentials are created based on user information retrieved from the
registry.
6. The credential is forwarded as the request is processed by different
architectural tiers of the application server.
