There's a module called Authen::PAM which can authenticate users against a PAM system (most modern unices have this)
This is indepent of the contents of the passwd file, and shadow passwd files (if used). Remember to use getpwnam($user) to put a lower limit on the uid of the logins allowed.

Hope that helps.
