very short authentication timeout for Lubuntu shutdown

[RüdiCoerdt]

Dear audience,

when trying to shutdown the system from the Lubuntu "Logout" menu item, a dialog pops up telling me that "System policy prevents stopping the system when other users are logged in. Authentication is needed to perform this action".

Fine, so far.

But, after 5 seconds, the dialog disappears, not giving me the chance to enter my password.

I could trace that down to polkit action "consolekit stop-multiple-users" and the lxsession-logout program, but then I'm lost. I can't see where the timeout can be increased.

When I logout all sessions on the system, the shutdown takes place immediately without authentication needed.
When I do other tasks, e.g. system updates, authentication dialogs come up and stay forever, long enough to enter passwords.

Status changed to 'Confirmed' because the bug affects multiple users.

lxsession-logout waits 2s for a reply from dbus from the shutdown/reboot request. That does not leave a lot of time to enter your password.
