Comment 49 for bug 861171

Here's another scenario: A laptop is shared by multiple members of a household. User A is the admin, User B is not.

User B steps up to laptop with the intention of shutting it down to leave with it. User A is currently logged in.

We have two choices here:

1- Present a warning dialog to User B saying that shutting down the laptop may cause User A to lose unsaved data in open applications, but allow him to shut the laptop down anyway.

2- Present an error message saying an admin is required to shut the machine down, at which point User B simply turns the machine off with the power button, and causes disk corruption.
