Description of problem:
Starting at init level 3, login as username; startx get Gnome desktop, open
terminal, sudo su -   
Wait half a minute before user is converted to root.  This time delay only
happens to the specific user who is logged in pre-GUI, and at the console.  Does
not have time delay for sudo through an ssh terminal nor for other users.

Version-Release number of selected component (if applicable):
RHE5.1, RHE5.2

How reproducible:
see above

Steps to Reproduce:
1.  Boot to initlevel 3.  Login as any user with account on machine
2.  startx open GUI (in my case, Gnome)
3.  Open terminal
4.  sudo su -   (yes, this user has sudo su - privileges)
5.  wait 30 seconds before prompt returns with user being root
  
Actual results:
wait 30 seconds before prompt returns with user being root

Expected results:
less than 30 seconds

Additional info:
Does not have time delay for sudo through an ssh terminal nor for other users.

Not a critical bug because functionality is not effected, just a time delay.  I
was puzzled by this for months and finally figured out that if I login using
init level 5; sudo speeds up to less than a second.  sudo must be going through
more steps when user logs in at init level 3 and then starts GUI?
