I was mentioning that many people are reporting similar problems (beit they are described slightly different) in other threads in this forum.  As for the problem with "the modules", I believe those have all been submitted already.

Upgraded my website yesterday afternoon.  Upgrade went smooth, but unfortunately "automatic" AD authentication is still not working. 

Stendor are you also running child sites like Jon and Dan are? The biggest problem I've seen with fixing it so far is that I haven't been able to re-create it however I haven't had a chance to test with child sites and, so far, that appears to be the setup that people who are having problems are running.

May and June is the time period when the instructors I support are done teaching and bored so they come up with all kinds of projects that they want done yesterday so I haven't been able to dedicate as much time as I'd like to the AD. However I will make a concentrated effort to test this out once the HDD has been replaced on my development system (should happen today).
