I have figured out the problem. It has to do with the way CVSNT
handles users and group (it doesn't distinguish between the two) and the way
Redhat type Linux distros create a group with the same name and GID as the 
by default, when adding users with the 'useradd' command. The two together 
are a
bad mix.
