Linux Password Requirements

I'm in the process of converting my network file servers from NT to Linux. I'm running Redhat 7 (2.2.16-22smp). What are the password requirements? I have tried to change some passwords and get messages back that it can't be changed because of various reasons like dictionary words, or too short. While I think this is great, I'd like to know the requirements without trial and error (though I've probably figured most of them out already) so I can pass them on to my users when I tell them the change is coming. Anybody know what they are?

Thanks!
 
Well, that's handled by pam. Look in /etc/pam.d/passwd for info there. The min is usually 4 characters. I would NOT recommend setting the min to zero as then it will allow null passwords. VERY, VERY bad!

If you're getting warnings about passwords being crappy then you are using cracklib, which is a pro-active password checker. You could uninstall cracklib rpm -e cracklib. Kinda of a nice tool though.
 
Damaged, thanks for the reply. I'm sure it is cracklib that is denying my password changes. I would actually like to use it, but I am sure I would get major grief from my 100+ users if I made them come up with non-dictionary passwords, although I do like the idea. Let me ask you this, what is the best way to get the Linux (Samba) box to have the same user password as the NT user password? Right now I am planning on giving each user a unique password on the Linux box, have them telnet to the Linux box, login with their new assigned password, and change it to their NT password. That way when they log in to the NT domain they will have access to both servers with the same password. It there any other or better way to do it? I have found a script that will generate all my NT user accounts on the Linux box, but it does not address the password issue. Thanks!
