With 12.10 it looks like gnome-disk-utility has moved to using udisks2 behind the scenes. However, it appears that polkit entries were not created for most of the potential actions that can be taken within gnome-disks. Many of the actions result in an error like the following:

An error occured

Not authorized to perform operation (udisks-error-quark, 4)

I've received the above error when trying to use gnome-disks to do things such as:
- starting a benchmark of a volume

All of these actions worked fine under 12.04 (via the gnome-disks precursor palimpsest and udisks).

Digging into this, it appears that there are a total of 38 possible polkit actions and local admins are only authorized by default for a total of three of them (via 10-vendor.d/com.ubuntu.desktop.pkla):

org.freedesktop.udisks2.filesystem-mount-system
org.freedesktop.udisks2.encrypted-unlock-system
org.freedesktop.udisks2.filesystem-fstab

Contrast this with the authorization for the previous udisk activities:
org.freedesktop.udisks.filesystem-*
org.freedesktop.udisks.drive-ata-smart*

Which covers 10 actions from what I can see.

For parity with previous releases I believe the following actions also need to be authorized for local admins:
org.freedesktop.udisks2.filesystem-mount [1]
org.freedesktop.udisks2.filesystem-unmount-others [1]
org.freedesktop.udisks2.ata-smart-* [2]

I'm sure there are others as there doesn't appear to be a direct 1:1 translation for some of the permissions.

This is a regression with regard to the previous 12.04 release and what local admin users were authorized to do.

[1] - covered previously by org.freedesktop.udisks.filesystem-*
[2]- covered previously by org.freedesktop.udisks.drive-ata-smart*
