Comment 11 for bug 474392

In Trusty, the relevant code has been rewritten to use logind instead of consolekit:
http://bazaar.launchpad.net/~indicator-applet-developers/indicator-session/trunk.14.04/revision/388

But note that when invoking org.freedesktop.login1.Manager->CanPowerOff() from a remote session, its output is:
"challenge"
instead of "yes" that an active (local) session produces.

That means that when indicator-session calls org.freedesktop.login1.Manager->PowerOff() with a "false" parameter to prevent prompting, then PowerOff() does nothing.

So, indicator-session should either
1) Hide the actions that return "challenge", or
2) Enable the prompt when the action specified "challenge".

(2) would allow remote users to shutdown the server, so I think everyone in this bug report prefer (1). :)
