Description (partial)

When federating with another vendor's server, CUPS successfully negotiates SASL authentication using the "from=" header in the stanza from the federated server. Once SASL is setup and CUPS receives the subsequent XML stream from the federated server, CUPS uses the "Certificate Subject Common Name (CN)" as the stored off authentication ID for the stream instead of the "from=" header. At this point the Common Name of the cert  does not match the the federated server's domain and all requests are rejected.
