ADFS 2.0 Proxy Error Event ID 364 – Encountered error during federation passive request
Posted by Brajesh Panda on December 15, 2014
This error may be related to IIS Service, Application Pool or System Time. Make sure App pools are not stopped, system time is not beyond Kerberos skewing limit (5mins~). I have DMZ Workgroup machines synching time with underline ESXi server & that particular ESXi has wrong date & hours config. So fixing clock on ESXi and ADFS DMZ server, resolved my issue.
