3.3.5.4.1 Processing Shutdown Request PDU
The structure and fields of the Shutdown Request PDU are described in section 2.2.2.1, and the techniques described in section 3.3.5.2 demonstrate how to process the contents of the PDU.
After the server has successfully processed the Shutdown Request PDU, it MUST send the Shutdown Request Denied PDU (section 3.3.5.4.2) to the client if a logged-on user account is associated with the session. If a logged-on user account is not associated with the session, the server MUST close the connection.
