Enable Yum As A Nightly Service

[Clint]

I'm having trouble getting yum to update nightly. I have a check in the 
box found under Redhat->System Settings->Service->yum, but it's not 
actually doing the updates, I checked yesterday by doing a manual yum 
update and seeing the list that were available, but choosing "N" (No) to 
see if the machine was doing it on its own. I'm checking now, and those 
same updates are available along with the kudzu update. I'm guessing 
there is something else that must be done to get yum to carry out the 
updates automatically each night besides putting a checkmark in that box 
-- what have I omitted? The current status is:

"Nightly yum update is enabled."

I found the following URL included a "patch" to the /etc/yum.conf file, 
but I haven't seen other folks' yum.conf patched in this manner.

I also searched Fedoranews.org, but didn't find a solution to this 
specific problem.
