2.1 Transport

All messages are transported over an RDP dynamic virtual channel, as specified in [MS-RDPEDYC], with the name Microsoft::Windows::RDS::AuthRedirection. The CredSSP server MUST send all requests over this channel using the formats specified in this specification, and the CredSSP client MUST listen for incoming connections on this channel, accept them, process incoming messages, and send responses on the same channel.
