3.2.1.3 Per SMB Session
Client.Session: An established session between the client and server. The following ADM elements are maintained for each SMB session established by a client:
Client.Session.Connection: The SMB connection associated with this session.
Client.Session.SessionKey: The cryptographic session key associated with this session, as obtained from the authentication subsystem after successful authentication.
Client.Session.SessionUID: The 2-byte UID for this session, representing the user that established the session. The UID is returned by the server in the SMB Header (section 2.2.3.1) of the session setup response. All subsequent SMB requests for this user on this connection MUST use this UID.
Client.Session.UserCredentials: An opaque implementation-specific entity that identifies the credentials that were used for establishing the session.
