Auto mounting NTFS formatted USB drives

[S B]

I was wondering if someone could provide me with some pointers on
fixing a rather odd problem I am having. I updated from Fedora 14 to
Fedora 15 -- clean install but carried over my home directory.

USB drives formatted as FAT32, ext3 automount fine under GNOME but
NTFS formatted drives don't. I have ntfs-3g installed and I can see
the drive being detected under /var/log/messages. but when I open
nautilus the drive isn't visible in the left pane (either mounted or
unmounted).

Strangely under KDE and even if I open Dolphin from within GNOME I can
see that drive and in Dolphin, I can click it and mount it and work
with it. When I do that with Dolphin I can see the messages relating
to ntgs-3g mounting the drive in /var/log/messages

At this point I am totally stumped. Why wouldn't GNOME automount this
drive but KDE (Dolphin under GNOME) will mount this drive just fine.

I am guessing this is some GNOME configuration but all my searches
turned up automount_media etc but I can mount FAT32 formatted USB
drives just fine.

Any pointers will be greatly appreciated.
