APAR status

  • Closed as program error.

Error description

  • Lost groupIds in id_token and introspection.
    The reason for that is we may read group from the dummy
    UNAUTHENTICATED subject. The fix is to check if subject is
    unauthenticated or not, and ignore the dummy subject.
    
    This is a regression between 8.5.5.8 and 8.5.5.9

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server Liberty who use the Open ID Connect  *
    *                  feature.                                    *
    ****************************************************************
    * PROBLEM DESCRIPTION: The Open ID Connect provider was not    *
    *                      returning the group IDs associated      *
    *                      with                                    *
    *                      the end user in the ID token            *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    The group IDs were not returned in the ID token because the
    code
    was incorrectly reading the group membership information from
    the special UNAUTHENTICATED subject.
    This is a regression between 8.5.5.8 and 8.5.5.9
    

Problem conclusion

  • The problem was fixed by not reading the group IDs information
    for the for the special UNAUTHENTICATED subject in the
    credentials.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 16.0.0.2 (there is no 8.5.5.10 in Liberty). Please refer
