The Case of the Missing CVS admin file

I've been having dilemma with CVSNT yesterday.  We need to create new users and passwords to go with them.  However, I could not seem to add new users via cvs passwd -a <username> :(  This morning, my teammate and I were wondering what was wrong.  I asked Butch about it and he suggested that I create new users by adding them into the passwd file and just leave the password blank.  I did that and when I tried logging on as one of the users, CVS wasn't letting the user in. Aiya~! We have three new users with us so we definitely needed this done because we aim to teach them about using Tortoise CVS this afternoon.  This morning, I tried cvs passwd again and  I kept on getting the complaint that only administrators can change passwords.

So after a couple of Google searches, I ended up checking the admin file and guess what? It wasn't there! We have no idea as to why it wasn't there. I definitely didn't delete that file because I hardly touch those in CVS Root.  In any case, I made a new admin file and added my username and two others who also act as part-time CVS admins. After that I tested it by trying if cvs passwd would do the trick. It did! Yay! Now we have three new users and we could start teaching them about CVS later. :)
