The pserver access method is STILL not working

Okay, if the problem is not a missing --allow-root, here are a few other possibilities:

• The user has no entry in the CVSROOT/passwd file, and the CVSROOT/config file has SystemAuth=no so CVS will not fall back on the system password file (or SystemAuth=yes, but the system password file has no entry for this user either).
• The user has an entry in the CVSROOT/passwd file, but there is no user by that name on the system, and the CVSROOT/passwd entry does not map the user to any valid system username.
• The password is wrong (but CVS is usually pretty good about informing the user of this, so that's probably not the answer).
• Everything is set up correctly with the passwd files and in /etc/inetd.conf, but you forgot an entry like this in /etc/services:

            cvspserver      2401/tcp
       

  so inetd is not even listening on that port to pass connections off to CVS.
