Linuxconf allows a non-root user to change the root password?!?!
I hope that isn't true, but if it is, better make sure Linuxconf is 
upgraded (I don't like it anyway, if he wants a config tool, try Webmin).

As for rebooting/shutting down, that should be a case of just checking 
the permissions of "reboot" and "shutdown" so that only root can execute 
- I suspect they're in /sbin/.
Unless he's talking about the option on the KDE Login Manager, in which 
case there is an option in the KDE control centre.

Don't know anything about sudo, check out the man page.

David.
