Dynamics CRM 2013 Outlook Connectivity Issue

Hi ,

We have a CRM 2013 system (with latest rollups) with IFD configured using ADFS 2.0. We are facing a strange issue while trying to configure the Outlook client. We are getting an "Authentication failed" exception. I have tried every possible solution available on forums, but non has fixed the issue. I am not sure of how to debug this issue. Need inputs.

Below is the last log entry from the Outlook Client Log file
