NIS groups HOWTO?

["Marcelo E. Magallon" <mmagallo@efis.ucr.ac.cr>]

Hi,

	How do I setup NIS groups in Debian? I have two machines, one
running up-to-date slink and the other one running hamm (if that matters).
The hamm machine is the NIS server. If I put 

	netgroups:	nis

on /etc/nsswitch.conf on both machines and 

	mygroup (,host-a,) (,host-b,) (,host-c,)

in hamm's /etc/netgroups and then

	/some/fs/	@mygroup

in hamm's /etc/exports, it doesn't work. What's the trick, or does "it's
kind of buggy" mean "doesn't work at all" in the libc6 documentation
regarding NIS groups?

TIA,
