Login fails with Windows Domain Authentication

Hi,

We have been using Windows Domain Authentication for some time now, but now it has stopped working
I found the stacktrace below in one of the log files.
Any suggestions where the problem lies?

We are using TeamCity Enterprise Version 5.1.4 (build 13550)
