CR# 6429610: Unable to create SSO token in ID-FF SSO use case

After setting up the Liberty Identity Federation Framework (ID-FF) sample 1, Federation succeeded, but SSO failed.

Workaround. Add the uuid of dsameuser to the com.sun.identity.authentication.special.users property in the AMConfig.properties file. For application authentication, dsameuser needs a non-expiring SSO token for the Access Manager server.
