Changing primary user group

[Mike Westkamper]

I need to set up a number of users and assign them to a primary group. For
example, I am setting up a FC1 box as a CVS server. The approach I am using
is to set up a number of cvs users and want to assign their primary group as
CVSUSER.

The GNOME applet doesn't seem to allow it. (add user / change properties)
And I have tried the traditional handtools but apparently there is someting
else that prevents adduser/etc from really working.

Any suggestions would be appreciated.
