As some of you may have seen, our site is working on overall *nix security and also prepping for an internal and external audit of our security. To that end, of the questions that keeps coming up is ensuring that when users change their password, it follows the policy for -stronger- passwords; min of 8 chars, alpha-numeric, one special, no dictionary, etc, etc.

Is there a software to make sure people don't pick 'easier' passwords akin to "happy1" that would integrate into the *nix OS? Meaning that the software would have various checks built in to ensure 'stronger' passwords are picked? So far I have found bupkous.

Hopefully this makes sense.

Thanks in advance.
