Is there a way in SLES/OES that I can make sudo work for GUI programs?
I tried having LUM-enabled users login and through GNOME and have them
open Terminal then execute sudo some_program, I get an X11 error. I
tried to do xhost +localhost before running sudo, I get the same thing.

I need to get a group of users sudo access in a GUI. They need to run
programs that require root access. I cannot give them the root password
otherwise, I can have them do "su -".
