[Wlug] SuSE 9.1 YaST2 online_update problem

Hi All, I just installed the SuSE SLES 9 (kernel 2.6.5-7.97). I can't get the 'YOU' utility to work. A box pops up asking for a username/password pair. I have this set up to run automatically every day at 5:00AM, but it fails with an error message "Unable to check for updates". If I run the YOU GUI by hand, a box pops up asking for authentication data (a username and password). During the installation of the O/S, it actually ran YOU successfully and downloaded some updates. I've looked at the /etc/sysconfig/onlineupdate file and I can't see anything obviously wrong. There is a password file in /var/lib/YaST2/you. I've tried using the root password, my personal password, but nothing works. What am I overlooking? Thanks, -Chuck
