Ohh dear..., i just got to work this morning and it's not working again? i had my testers clear their cache/cookies but it still does not work, however, i restarted my web server again and one of my testers got in? very strange... I have just restarted my webserver again and the tester that could get in after the first restart now cannot get in and i'm very confused. Most of our applications use secure authentication for AD queries, so i tried changing that, still no joy. We have however had success with all testers if the following steps are carried out before attempting to login:
1. Add the users domain username and details to the DNN user table in the database
2. Get the user to clear their cache/cookies
3. Browse to the site and login is successful.
If i try this i still cannot get in automatically, i can if i use the windows login button and go that way in. We can populate the user table from an export from out AD store, this would be a work around though.
