Active Directory Provider Problems

I just returned from a three day camping trip with my son's grade six class in the foothills of the Canadian Rockies to a mailbox full of people having problems with Active Directory. It was quite a shock to the system as it's been a long time since I was totally without internet access for more than a day.

It looks like a change somewhere in the core has broken AD websites that use full authentication (the authentication line is uncommented in the web.config) but mixed-mode authentication still works (users log into the DNN site using DOMAIN\Username and their AD password or use a link to the windowssignin.ascx) in single portal installs (multiple parent/child portals is another matter). I've been able to recreate it on a test site but then was able to fix it by deleting the AD user from the DNN site and then visiting again. Once the account was recreated everything worked fine. However, this is not an ideal solution (deleting all current users) on a portal that has thousands of users.

I've got today and tomorrow to catch up on things here at work and then I'm on holidays and will be able to dedicate my full attention to the problem rather than the 15 minutes here and 30 minutes there that I've been able to the last couple of weeks but wanted everyone to know that we're aware of the problem and are not ignoring it.
