At the upstream identify provider, we return the NameID with the value for the logged user. However, this value doesn't load at the nameidentifier claim on the WSFederation application.
You can try one of the following to get the NameID value:
- Use NameIdentifier claim for Identity bearing claim on the authentication connection.
- Make the mapping claim transformation to map the NameIdentifier claim to another claim then attach it to the authentication/protocol connection.
