ZMD: Novell Update Channels missing!

[acapriolo]

Hi,
i have a strange situation ZMD/YAST about channels:

rug ca says

Sub'd? | Name | Service
-------+----------------+---------------
Yes | ATI-Drivers | ATI-Drivers
Yes | nVidia-Drivers | nVidia-Drivers

No "nu.novell" channel!!

But, if i use Yast online update, i get this error:
Cannot access installation media
SLED10-UPDATES
(with a 403 error...)

After the refresh of the sources it says that i have two new sources:

...@nu.novell.com/repo/$RCE/SLED10-SP1-Online/sled-10-i586/?alias=SLED10-SP1-Online
...@nu.novell.com/repo/$RCE/SLED10-SP1-Updates/sled-10-i586/?alias=SLED10-SP1-Updates

but on ZMD and rug i only have ATI and Novell channels...

I've tried TID 3303599 (two times) but nothing happens...
Any ideas?

Thanks in advance!
