Hi!
I couldn't find the thread in the archives, but the PAM way definitely works on SuSE7, with caveats...
...you have to add the username to the wheel group in /etc/group, for some reason it's not enough to make the primary group wheel. And you can't su to a member of the wheel group, then su root either.
I cannot try this now to see if it still works, but in the past I've used the following workaround for this: use "su -" to su to a member of the wheel group (the "-" makes this a login shell), and then use either a "su" or a "su -" to become root. I don't know how to block this approach, given that it still works, and also I don't know whether or not this still works at all nowadays: I've used it ages ago.
