access rights to branches

[Shem Mazur]

Hi,

I have a CVS user who continues to checkout modules or update files from
the wrong branches.  Can I restrict her ability to update from
particular branches or main trunk?  The only thing I can find about
access rights with CVS is to do with Unix file permission.... this is
fine if you want to stop someone from accessing a project, but not
enough if you just want to restrict access to a particular branch in the
project.

Any help much appreciated (she's driving me nuts!!! ;)
