need to allow non-root user to run shutdown

[Billy Davis]

We are running RH 7.2 and need a way to allow a non-root user to login in text mode, and select a Shutdown option from a text menu that is displayed by a shell script.  Currently, when the user selects Shutdown, the script tries to execute a '/sbin/shutdown -ah now' command, but the system replies with: 'shutdown: must be root'.   Is there any way to allow the command to work with a non-root user?   Thanks bdavis
