IE Authentication Prompt, Pass-through authentication stops working
Posted on 2009-07-15
We use Business Portal 2.0 (built on Sharepoint 2.0) for our intranet. We use pass-through authentication for the intranet.
Through AD (2003) we enforce a 90-day password expiration policy.
On random machines (WinXP, IE7), when they have to reset their password, IE fails to register the change and the authentication prompt begins to pop-up every time they try to go to the intranet. They can manually enter the credentials every time and it works, but we want the pass through authentication to work.
This does not seem to happen consistently across the network (e.g. not all IE7 users have this issue as far as we can assess).
Our really lame workaround has been to uninstall IE and reinstall and that mostly works. However, I have a machine on hand for which this is not resolving the issue.
Can anyone give me pointers on where I can look to see if I can flush out the old password...Clearing the cache, cookies, temp internet files, etc., does not cut it?
Thanks in advance for any feedback.
