Problem Cause

When Authorizing the FAS, it is going to query the following Active Directory partition to get the Certificate Authority Server Information to enroll the certificate.

CN=Enrollment Services,CN=Public Key Services,CN=Services,CN=Configuration,DC=yourdomain,DC=com.

If there are stale entries or old CA servers listed there, it is going to query all the servers and not knowing which one is the correct one. The time out happens because of this reason.

Authorizing FAS fails with error "The Request Channel Timed out while waiting for a reply after 00:01:00" when trying to submit the certificate request to the CA server.
