I'm not sure if this is what you're looking for, but PAM has several 
plugins that might help with this. These libraries enhance the 
authentication system to do all kinds of things.

Check out the PAM HOWTO here:
http://www.kernel.org/pub/linux/libs/pam/Linux-PAM-html

If you want to enforce strong passwords with dictionary checking, 
minimal password lengths, certain numbers/types of characters, look at 
pam_cracklib.

Good luck!
