New Users unable to SU

[Gerard Seibert]

I seem to have developed a problem on my system. I can add new users
either via the adduser script or using 'sysinstall'. The problem is that
none of them can become root. They are all in the 'wheel' group, so it
should be working. I am the only user that can access the root. They can
use 'sudo' but that doesn't fix the problem.

I have no idea where to begin to look for an answer. I hope someone can
assist me.
