Granting permission for powering off to a regular user

Granting permission for powering off to a regular user can be accomplish as follows by using Polkit:

1. Add the regular user to the power group by usermod -a -G power <username>.

2. Create a file named i.e. /etc/polkit-1/rules.d/40-allow-shutdown.rules with the following contents:

   /* Allow specific users to shutdown without authentication */
   polkit.addRule(function(action, subject) {
      if ( ( action.id == "org.freedesktop.login1.power-off" ||
             action.id == "org.freedesktop.login1.power-off-multiple-sessions"
           ) && subject.isInGroup("power") ) {
        polkit.log("Powering Off permitted for subject" + subject)
        return polkit.Result.YES;
      }
   });
