Our standard answer when someone asks for $random-auth-method is to
suggest that they find a PAM module for it and use PAM. I wouldn't
want to claim that PAM is a particularly great interface for this
sort of thing, but it's out there and I don't know of any serious
competition. The alternative of supporting $random-auth-method
directly doesn't scale very nicely...
