Normally when users do graphical login, they can use the menu option to power-off the system. If we want to disable non-admin (non-root) users from powering of the system we can use:

  1. Create '/etc/polkit-1/rules.d/55-inhibit-shutdown.rules' with: 
    polkit.addRule(function(action, subject) {
    

    if ((action.id == "org.freedesktop.consolekit.system.stop" || action.id == "org.freedesktop.consolekit.system.poweroff") && subject.isInGroup("admin")) {
    

    return polkit.Result.YES;
    

    }
    

    else {
    

    return polkit.Result.NO;
    

    }
    

    });
