Bug Description

In lightdm-gtk-greeter we use the call "lightdm_get_can_restart" to check whether lightdm supports restarting and it works up to Raring, but the same call fails in Raring.

As there was a switch to logind in Saucy, I suspect that this might have something to do with this call not having been ported to support logind (could be something else entirely though).

The restart menu entry is present after booting the system, but disappears after first logout.

Checking /usr/share/polkit-1/actions/org.freedesktop.login1.policy it's easy to see that poweroff has different a different policy than reboot.

<action id="org.freedesktop.login1.power-off-multiple-sessions">
<allow_active>yes</allow_active>

<action id="org.freedesktop.login1.reboot-multiple-sessions">
<allow_active>auth_admin_keep</allow_active>

So the question is, how should lightdm-gtk-greeter react to the "challenge" value it receives now (instead of "yes")?
