sudo works, su doesn't

Specs: Red Hat Enterprise 4
I know the root password and can ssh directly to the server as root, but what I can't do is ssh to the box as a normal user and su to root (I don't ever like logging on as root). I can 'sudo su root' just fine, but when I try 'su -', I receive 'su: incorrect password' (again, I know the root password just fine).

/etc/sudoers has:
root ALL=(ALL) ALL
%wheel ALL=(ALL) ALL

And /etc/group has:
root:x:0:userx
wheel:x:10:userx

Any ideas? I have surfed the web high and low, and have found work-arounds, but I would like to determine what the root cause of this behavior.
Thx, UtahTechDad

This is the Networking forum. This question would be better asked in the Linux or UNIX forums.

You shouldn't be able to ssh as root. It is already borked.

You have confused a group named wheel and a user named wheel.

http://www.sudo.ws/sudo/sample.sudoers for example.

"Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, are in my top 10

Not sure what you mean here jefro. I do it all the time. Either when logged in as root (ie: shh xxx.xxx.xxx.xxx) or when logged in with my normal 'user' level account and I'm connecting to another Linux/UNIX box as root (ie: ssh root@xxx.xxx.xxx.xxx) Both work perfectly fine for me.
