Description Brian Z 2001-08-18 14:19:23 UTC
Description of Problem:
At the GDM login prompt, I am able to shutdown and restart the server 
without logging in.  This shows a lack of security, since any user can 
walk by the computer and shutdown/restart it.  Win NT Server & 2000 
Server force the administrator to log in to use these options.

Version-Release number of selected component (if applicable):

How Reproducible:

Steps to Reproduce:
1.  At the GDM Login Prompt, click System
2.  Click Shutdown or Restart
3.  Watch System Shutdown/Restart

Actual Results:
Server restarts/shutdown.

Expected Results:
To be Prompted for root password to restart/shutdown.

You can also type "ctrl-alt-del" at the console, always have been able to.

If you want to disable this, there are options in /etc/X11/gdm/gdm.conf, and 
you can turn off ctrl-alt-del in /etc/inittab. People can still hit the power
button though, if you haven't physically concealed it.
