Ticket #48410 - 389-admin - Unable to remove / unregister a DS instance from admin server
    
    Description: The cgi ds_remove missed to map ServerAdminId.
      NMC_ErrInfo: The map value 'ServerAdminID' for key 'as_uid' did
      not map to a value in any of the given information files.
    This patch adds the mapping using admpw.conf.
