## PURPOSE: Show a list of userids that appear in both
##            1) the list of SGI userids (via NIS, 'ypcat passwd')
##	    and 
##            2) the list of userids in the $SERVER:/etc/aliases file.
##
##          I.e. show the userid *matches* in the two lists:
##             1) a list of userids that can login to SGI machines 
##             2) a list of userids with mail aliases (in a
##                                      'central' /etc/aliases file).
##
##  Can be used to indicate to SGI AppAdmins & SysAdmins as to userids
##  that are authorized to login to SGI's AND that have a corporate
##  e-mail address in $SERVER:/etc/aliases.
##
##          Helps corroborate 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'.

                                                  Run at host $THISHOST

A list of userids with BOTH
    1) authorization to login to SGI machines (as per NIS, 'ypcat passwd')
and
    2) a corporate mail alias entry in $SERVER:/etc/aliases .

***************************************************************************
* Contact an SGI System Administrator if your userid does NOT
* appear in this list, yet you are able to login to SGI machines
* on the NNS network. 
* 
*    A line with your userid and corporate-mail-address
*    is probably missing from the 'central' /etc/aliases file.
* 
* Have an SGI System Administrator add
*             your userid and corporate-mail-address
* to the 'central' /etc/aliases file.

This script/utility lists those SGI *USERIDS* in BOTH

    Example line in an /etc/aliases file:

  - a list of users allowed to login to SGI machines
