Configuring wheel group problems

[LordMorlock]

Greetings all.

I'm running Red Hat Linux 6.2 and I edited the group file, adding my username to the wheel group thus:

wheel:x:10:morlock

Now, as far as I understand it, this should only allow me to su to root. It still allows other users to though. Is there something I have to activate, or have I just got it all wrong???

Any assistance would be appreciated.

Add the following line to /etc/suauth (and make that file readable only by root):

ALL:ALL EXCEPT GROUP wheel http://discussions.linuxplanet.com/biggrin.gifENY

UBB interpreted the line as a smiley
The correct line to add is:

ALL:ALL EXCEPT GROUP wheel:DENY
