I required information on CVS passwd authetication on  NIS+

I have redhat box which ia configured as CVS server and NIS +

I ned information on whether CVs takes passwd from .etc.passwd  files
or NIs+ passwd file

whether CVs supports NIS +  if so  please provide the details

short: as long as CVS is using the system for authentication information, CVS will use the same mix of /etc/passwd and NIS that the system uses.

As long as you are using :ext: and rsh|ssh, cvs does not do the authentication, rsh or ssh does it.

RSH and SSH[1] do authentication through the hosts mechanisms (if not using rhosts, or ssh keys) and with thus use NIS if the rest of the host login methods do. Many folks consider SSH with ssh or PKI keys to be more secure & audit-able, and there are resources[3] for setting it up.

if you are using :pserver: and you don't have a passwd file in $CVSROOT/CVSROOT/, then CVS will authenticate using the system, i.e., if the system uses NIS, then CVS will use NIS. BTW with :pserver: your passwords are sent in the clear across the network and stored with a well known xor in HOME/.cvspass [3], so it would be reasonable to assume that after :pserver: use the password is compromised.
