User disk mounting

[Jeremy Sanders]

Hi - Using dolphin I (or any user) can click on an unmounted system disk (an 
internal SATA drive, with a hard disk icon) and it is mounted without any 
passwords with a single click. This is Fedora 12 x86-64.

I can't see why this should be enabled by default from the polkit 
configuration:

xx:/home/jss:# pkaction --action-id 
org.freedesktop.devicekit.disks.filesystem-mount-system-internal --verbose
org.freedesktop.devicekit.disks.filesystem-mount-system-internal:
  description:       Mount a system-internal device
  message:           Authentication is required to mount the device
  vendor:            The DeviceKit Project
  vendor_url:        http://hal.freedesktop.org/docs/DeviceKit/
  icon:              drive-removable-media
  implicit any:      no
  implicit inactive: no
  implicit active:   auth_admin_keep

xx:/home/jss:# pkaction --action-id 
org.freedesktop.devicekit.disks.filesystem-mount --verbose
org.freedesktop.devicekit.disks.filesystem-mount:
  description:       Mount a device
  message:           Authentication is required to mount the device
  vendor:            The DeviceKit Project
  vendor_url:        http://hal.freedesktop.org/docs/DeviceKit/
  icon:              drive-removable-media
  implicit any:      no
  implicit inactive: no
  implicit active:   yes

If it's an internal disk, I would have thought filesystem-mount-system-
internal was the appropriate option, but this is set to auth_admin_keep 
which should pop up a dialog box asking for a password.

Is there another setting I should be looking at?

Thanks
Jeremy.
