[CentOS] CentOS 6.3 - KDE login screen configuration problems

We generally use CentOS for some servers, and so do not use a GUI
interface. However, I have recently installed CentOS 6.3 onto a PC with
KDE. I am familiar with KDE as I use it with Fedora for my work PC.

The problem is that we would like to configure the login screen, so that
it does not show the user list, that it does not allow the shutdown or
reboot commands (from the login screen), and if possible to remove the
30 second confirmation timer that occurs when logout (via 'leave') is

I have gone into the 'System settings->Advanced->Login screen', and
disabled both local and remote shutdowns and reboots. I have also
disabled the showing of the user list, and disabled logout

However, none of this has had any effect. The login screen remains the
same - showing the userlist and shutdown/reboot commands, and logging
out still shows the 30 second confirmation timer.

I have compared the /etc/kde/kdm/kdmrc file from the CentOS PC to my
Fedora PC and they are similar. (I make the same changes to my work PC,
and these take effect.)

Anyone any ideas about this?
