For Web services, you can complete authentication and authorization using an LTPA token.
The LTPA token Authentication and Authorization are supported only in the following configuration:
Capability
Configured with a security policy set and binding that defines that an LTPA token is present for authentication; see Authentication. The broker provides only LTPA pass-through support, which means that the LTPA token is extracted and passed to an external security token service (STS) for validation. The STS to be used is specified in a security profile. The STS processing can be used to implement authentication and authorization based on the LTPA principal and realm.
Configured with a security profile defining the Policy Decision Point (PDP); see the PDP section that follows.
Configured by using a WS-Trust v1.3 STS security profile specifying authentication, authorization or both; see Creating a security profile for WS-Trust V1.3 (TFIM V6.2).
