It would be a tremendous asset for me if I could use NIS + netgroups to
implement login restrictions on my machine.  The way I'm most familiar
with is to place "+@name" and "-@name" into the password file, which then
includes users in the named netgroup from the NIS passwd map.

Has anybody else done any work on this?  If not, is it be reasonable
to modify getpwent(3) to do the appropriate thing?  (Please, I do recognize
the weaknesses of NIS, lectures and soapboxes aren't necessary. ;-)
