Can only reboot or halt as root
 

as of today i can only use the reboot and halt commands as root or super user.... when i use the GUI Config tool in KDEs control center it tells me that its configured so all users can use those commands localy and only root can remotely (the way i want it)....

any ideas?

For my part I did (assuming you're in the "users" group)

$ su
# visudo
--and I add this line :
%users localhost=/sbin/shutdown -h now

If you are absolutely unconcerned about someone else using your system
chmod +s /sbin/halt
chmod +s /sbin/reboot
