Using distributed identity mapping for SAF
In this release of WebSphere® Application Server, you can use z/OS® System Authorization Facility (SAF) security to associate a SAF user ID with a distributed identity.
About this task
When you use this feature, you can maintain the original identity information of a user for audit purposes and have less to configure in WebSphere Application Server.
You can log in to a WebSphere Application Server application with the distributed identity of the user. The filters defined in the z/OS security product then determine the mapping of the distributed identity to a SAF user.
Note: The SAF distributed identity mapping feature
is not supported in a mixed-version cell (nodes prior to WebSphere Application Server Version 8.0).
