XFCE4 Session Manager: enabling shutdown/reboot option

I found that the line below was correct but I had to add the halt, reboot 
and shutdown now commands (HALT, REBOOT, SHUTDOWNNOW are aliases) so I 
could shutdown or reboot from myuser.

myuser ALL=/usr/libexec/xfsm-shutdown-helper, HALT, REBOOT, SHUTDOWNNOW


Cmnd_Alias      HALT = /usr/sbin/halt
Cmnd_Alias      KILL = /usr/bin/kill
Cmnd_Alias      REBOOT = /usr/sbin/reboot
Cmnd_Alias      SHUTDOWN = /usr/sbin/shutdown
Cmnd_Alias      SHUTDOWNNOW = /usr/sbin/shutdown -h now
