## PURPOSE: Shows mismatches between SGI userids (via NIS, 'ypcat passwd')
##	    and userids in the $SERVER:/etc/aliases file.
##
##          Can be used to alert SGI SysAdmins as to userids (and
##          corresponding corporate e-mail address) to add to
##          $SERVER:/etc/aliases.
##
##          Facilitates proper operation of mail forwarding from SGI 
##          applications (like mail notifications within I-DEAS,
##          for Team Data Management part/assembly updates), via
##          Unix mail commands like 'Mail'.

##                    'userids' or 'userids_bydept' in $FEDIR/scripts
## Last Update: B. Montandon  17Nov2000 Improve report format; move

MIS-MATCHES OF SGI LOGIN-USERIDS & SGI MAIL-ALIAS-USERIDS.

***************************************************************************

   If your userid appears in the left column and you are NOT
   receiving mail-by-userid, such as I-DEAS Team notifications
   of part/assembly updates, then it MAY be the case that
   a line with your userid and corporate-mail-address is
   missing from the 'central' /etc/aliases file.

Contact an SGI System Administrator to have mismatches
for CURRENT employees corrected --- example: corporate mail
address is needed in $SERVER:/etc/aliases.

Also, contact an SGI System Administrator to have
OLD employee userids removed.
***************************************************************************

Some more information is at the bottom of this list.

This 'MIS-MATCHES OF SGI LOGIN-USERIDS & SGI MAIL-ALIAS-USERIDS' utility
can be run via a 'mailtools' command-toolchest drawer.
____________________________________________________________________________

This script/utility lists the DIFFERENCES (MIS-MATCHES) between

  - USERIDS in the 1st column of the $SERVER:/etc/aliases file

    (a file for translating userids to corporate mail addresses)

    Example line in an /etc/aliases file:

                 abc00:cooper_ab@nns.com

and 

  - USERIDS allowed to login to SGI machines 

    (given by NIS, 'ypcat passwd'). NIS = Network Information Service

    Example line from an NIS 'ypcat passwd' query:
     
     abc00:...:20:A B Cooper      ,e99:/usr/people/abc00:/bin/ksh
