Try sudo. Limit the user just to execute shutdown and prompt it for 
password. check sudoers file. Add flag -y to shutdown command.

Other option is let user execute a script with sudo, then the script 
executes shutdown in the background (so the user can log off normaly). 
Should be mode 700 and not setuid but owned by root, It will be executed 
as root. Depends on your os type and init level, shutdown will unmount 
all mounted points and give control to the basic system avalible (ej: 
openboot on Sun)
