Can anyone suggest what the best way to enforce strong passwords on a
FreeBSD system is? We would like to add the functionality to our system to
require users to have at least one alpha character and one numeric character
in their passwords. And if possible also require them to use special
characters in their passwords. I know we can try password cracking as a way
to ensure strong passwords, but I think we want to go with a more proactive
approach.

I looked at the login.conf man page, but it looks like the only option
available is to require mixed case passwords. I also looked briefly at
Npasswd+, but had trouble getting that to compile on FreeBSD. Any
suggestions you might have would be greatly appreciated.

Thanks,
Rick
