APAR status

  • Closed as program error.

Error description

  • The program fekfomvs requires the following UNIX permissions and
    extended attributes: rwxr-xr-x...aps-
    
    The extended 'a' attribute means that the program behaves as if
    loaded from an APF-authorized library. Without that extended
    attribute fekfomvs cannot authenticate a user attempting to
    connect to a remote system. This misconfiguration
    should cause the RSED to error out and prevent the
    authentication. But currently the Daemon authentication service
    fails to handle this and lets the authentication continue
    as successful.

Problem summary

  • ****************************************************************
    * USERS AFFECTED: 1. All users                                 *
    ****************************************************************
    * PROBLEM DESCRIPTION: 1. fekfomvs is required to be APF       *
    *                      (extended 'a' attribute), the           *
    *                      required bit setting is 'aps'.  When   *
    *                      its bit setting is not proper, RSE      *
    *                      may fail to properly authenticate a     *
    *                      user.                                   *
    ****************************************************************
    1. When it is not APF, fekfomvs cannot perform its verifyUser
    command to authenticate a user. RSE authentication service
    fails to recognize the issue and let the authentication going
    through as sucessful.
    

Problem conclusion

  • 1. Have authentication catch the issue and fails the
    authentication. This could also affect RSEAPI.
