cvs pserver group settings

[Aditya . Sanghi]

Hi!

Programmers at my site are able to update, commit to the repository, but they
get this warning:

cvs update: warning: unrecognized response `setgroups: Not owner` from cvs
server

It's irritating and I would like to fix it. Can someone please shed more light
on it?

thanks in advance,
aditya
