But what do you do in the case of hardware on the client being in a
group that is below 100? Unless I'm not understanding your reply (I'm
new to NIS). On Ubuntu (and therefore Debian, I assume), audio,
plugdev, floppy, cdrom, and other important GIDs are below 100, so you
can't grant or restrict access with NIS from the server. If all you
want to do is grant or restrict access to files NIS would seem to work
just fine across a number of different clients/OSs, but when it comes
to hardware it seems to fall short - again, if I'm understanding
things correctly. And although I don't have this problem in my home
network, what happens if you want to take someone's floppy access away
and they're in another town, do you have to drive over there?
