[cvsnt] chacl lock branch command

[Soneji, Ketan]

I am using cvsnt version 2.5.03 build-2260 on linux platform. I am
trying to understand the access settings using chacl command. My motive
is to lock specific branches which may also include the root(HEAD
branch). I want to lock the branch for everyone and only give read
access to everyone. I may also want to unlock the branch.
 
I am executing the following command in the repository root directory on
the server inorder to lock a specific branch:
 
cvs chacl -R -r Maint_Branch_0_2 -m "0.2 has been locked" -a
read,nowrite,notag,nocontrol,nocreate tracker/
 
where "Maint_Branch_0_2" is the branch name and "tracker" is the module
name
 
But I am still able to checkin files in the above branch.

my CVSROOT/config file has the entry:
AclMode=compat

Apart from the above CVSROOT/config setting is there any other
configuration parameter required to enable ACL?
 
I would be grateful if anyone can guide me in how and from where to
execute the branch lock command. Will there also be a way to unlock the
branch again?
 
Thanks in Advance,
Ketan
