Method for Administering LAN Server Groups In Distributed Computing
Environment

      Disclosed is a method for administering IBM* OS/2* LAN Server*
groups in a Distributed Computing Environment (DCE**).

      In IBM OS/2 LAN Server Enterprise, the following LAN Server
special groups exist to enable legacy LAN Server clients to access
resources on an enterprise server:
  1.  ADMINS
  2.  USERS
  3.  GUESTS

      In a LAN Server environment, the membership lists of these
groups cannot be modified directly and these groups cannot be
deleted.  LAN Server updates the membership list of these groups when
a new user is added or when a user's privilege is modified.  For
example, if a user with administrator privilege is created, that user
is added to the ADMINS group, and if the privilege level of the user
is changed from an administrator to a guest, that user is deleted
from the ADMINS group and added to the GUESTS group.

      In the LAN Server Enterprise environment, the ADMINS, USERS,
and GUESTS groups exist in the DCE registry.  Since the DCE
interfaces for updating the registry operate on these groups like any
other DCE groups, the membership lists of these groups can be updated
directly or the groups can be deleted.  This causes undesirable
results when the updated information is synchronized with the LAN
Server database.

      The following updates were made to the Registry Synchronization
Process (RSP) code of the LAN Server Enterprise product.  The RSP is
a background process which receives updates from the master replica
and applies them to the LAN Server database.

      The following pseudocode illustrates the alogorithm for
processing any additions to the membership lists of the three special
LAN Server groups:
         If (group is a special LAN Server group)
           Update the user's privilege in the LAN Server
