Cannot shutdown when power button pressed -> how to...?

[hhtmp88]

Dear all,

I know that, for UNR9.10, I can set in the "power management" menu that the pc will shutdown itself when the power button is pressed, however in Mythbuntu, it DOESN'T!
-> a pop-up window requesting authorization is shown and I have to key-in my password before the PC be shutdown -- The pop-up message states:
===============================
System Policy prevents stopping the system when other users are logged in.
===============================

so any idea on how to disable this authentication request?

Thanks for any kind of help!
