A user can end another user's or even root's session by shutting off or rebooting the system. Reproducible: Always Steps to Reproduce: 1. Start the computer. 2. Log in as user in KDM. 3. Switch to virtual terminal 1. 4. Log in as root. 5. Switch back to virtual terminal 7. 6. Start Konsole. 7. Execute "who". This shows both root and user. 8. Press Ctrl+Alt+Delete. 9. Press enter. Actual Results: The computer is shut off without even a warning! Expected Results: A user is not allowed to end another user's session (especially not root's). (Someone might prefer to just have a warning as an option, but forbidding would suffice for me.) Even better would be if a user is can not shut down or reboot even if all other remaining sessions are his own. He would have to exit each of them (except the last one, from which me may shut down). That can prevent data loss but is not as important as protecting other user's (or root's) sessions. This is especially annoying if root has been emerging openoffice since a few days and has to start over when he discovers that the user has triggered this bug.
I don't know if this is a KDE specific problem or perhaps something deeper down, but let's start off investigating your `emerge --info' and perhaps the version of KDE that you are using...
Created attachment 179498 [details] emerge --info KDE version is 3.5.10.
Some of this behavior is determined by settings in KControl (for KDE-3.5.x). System Administration -> Login Manager -> Shutdown Regarding CTRL+ALT+DEL, I believe that can be restricted too, but the method escapes my memory. Perhaps someone else can provide a clue.

Just to remind: Oswald Buddenhagen wrote in comments #3 and #4 of the KDE report (see URL) that this is supposed to be fixed and work properly. Other user's sessions will be protected as long as they show up in the 'who'-command. But it does not work.
(In reply to comment #2) > KDE version is 3.5.10. KDE 3.5.10 has been masked for removal, reopen if you still experience this with KDE4.
