Claims authentication event ID 8306 error, cannot start USPS service after expired password change

Question

About 2 days ago the password expired for the farm account due to someone not using the function to never expire passwords. Anyways, after this I went thru CA and changed the password but now I can't get the User Profile Sync Service to work. If I look in the Event Viewer I keep on getting an error in SharePoint Foundation with Event ID 8306 and the message is The HTTP request is unauthorized with client authentication scheme 'Negotiate'. The authentication header received from the server was ''.. Anyone who can point me in the right direction on where to look? I also have the issue of the FIM not starting but I'm guessing this is all related to eachother.

I can also add that the User Profile Synchronization Service is stuck on "Starting" and that I've recreated the User Profile Service Application several times now.

Answer 1

I "solved" this by backing up the site collection and then reinstalling without reinstalling Sharepoint (followed Todd Klindts guide on his blog ).

Answer 2

Try this one

Upon receiving this error message, the Authentication settings for the SharePoint Web Services (this is the site responsible for issuing the security tokens).

Under IIS 7 > Sites > SharePoint Web Services > Authentication > Windows Authentication (enabled) > Advanced Settings > Check Enable Kernal-mode authentication.

The "Enable Kernal-mode authentication" was unchecked, upon checking this setting and completing an IISRESET (from PowerShell) the Security Token issue was resolved and the alert no longer shows in Central Administration.
