I'm trying to setup a CVS server installed on Red Hat Linux
for few Windows clients using their Active Directory username and

So far so good... they authenticate on the system through Kerberos5
and SSH
and make checkout, commit and import without any problem.
All the users are part of cvs group and the directory is owned by cvs
user and cvs group.
The problem is: how can i prevent users to edit files directly in the
CVS repository
on the server with an editor through the ssh shell?
Correct me if i'm wrong, but they have to modify the code only
doing a checkout on local machine and then a commit changes.
I've tried to prevent users login with ssh, but doing so also cvs is
blocked.
Thank you in advance for any help,
best regards,

It does not come by default with RH, but it compiles fine. You don't set
it up for global acces, but only for telnet and ssh and only allow a
small number of users (say users members of the group cvsadmin) to login
to the box.
Yves,
would you mind explaining how that can be used to prevent the user from
executing programs other than cvs through the ssh connection?
I ask be cause I am interested in the capability too, but did not see (while
reading that page) how sag-pam_group accomplished the above.
Fabio,
From the googles I have done, I am seeing the following as options:
Authprogs:

authorized_keys tweaking:

ForceCommand & Match:

I have not used any of them yet.
