This will likely fix the problem for you. Put this in
/etc/PolicyKit/PolicyKit.conf and restart hal, /etc/rc.d/hal restart.
<config version="0.1">
<match user="yourusername">
<match action="org.freedesktop.hal.storage.*">
<return result="yes" />
</match>
<match action="hal-storage-mount-fixed-extra-options">
<return result="yes" />
</match>
<match action="hal-storage-mount-removable-extra-options">
<return result="yes" />
</match>
</match>
</config>

Hello,
I just upgraded to networkmanager 0.7, which comes with a hal upgrade. Following this new upgrade, I am unable to mount devices from Dolphin as I used to be able to -- it now gives me a "PermissionDeniedByPolicy mount-removable-extra-options no" error. I followed the instructions on [1] but it did not help. Can someone help me?
-- Thanks, Leonid
