Group permissions to branches

[Danial Islam]

I'm not sure if I posted this already, but here goes again:

In my repository I have set up a main trunk with two branches coming out
of it, e.g.  Branch A and
Branch B.    Is it possible to restrict Branch A to a certain group of
users, and  Branch B to another group of users?  How would this be done
in UNIX?

How would I modify the CVSROOT/passwd file to accomodate this? Right now
my passwd file currently has [unix ID]:[encoded password] for each user.

Any help would really, really be appreciated!
