Comment 28 for bug 1008344

I previously just tried this under "su", but I fell into the trap that this looks at allow_inactive, not allow_active. Sorry about that.

I filed an upstream polkit bug to get access to this information, as this is IMHO the only clean way of fixing this. Until then, I suggest to either leave that bug open or always show the "Apply system-wide" buttons as that will at least make the functionality available (but it may not work for non-admins).
