Can't unlock User Accounts

[Shahar Or]

Even though my user is in the sudo group, that user can't modify system users using the control center.

The Unlock button in User Accounts is unavailable and pointing at it pops up a tooltip saying "System policy prevents changes. Contact your system administrator".

I've tried two users that are in the 'sudo' group and they both have the same issue. This is both through an LTSP client session and through 'ssh -X <server> gnome-control-center'.

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

Anyone that's having this issue,
I'm running it on a btrfs filesystem. Perhaps it is related?
Thanks

Thank you for your bug report, is that specific to the users panel? Can you install packages from software-center for example?

[Shahar Or (mightyiam)]

Dear Sebastien,

Installing via Software Center works, yes.

Perhaps I should set status to 'new'? Instructions are to not 'confirm' my own bugs. Although it has been confirmed before.
