You can configure identity assertion authentication. The purpose of identity assertion is to assert the authenticated identity of the originating client from a web service to a downstream web service.
This task is used to configure identity assertion authentication. The purpose of identity assertion is to assert the authenticated identity of the originating client from a web service to a downstream web service.

You must specify the user ID of the special BasicAuth credential in a trusted ID evaluator on the downstream web service configuration. See the information on trusted ID evaluators.
Complete the following steps to specify how the client collects the authentication information:
