3.1.5.1 Receiving a POP3_NTLM_Supported_Response Message

The expected state is sent_authentication_request.

On receiving this message, a client MUST generate the first NTLM message by calling the NTLM subsystem. The NTLM subsystem then generates NTLM NEGOTIATE_MESSAGE as specified in [MS-NLMP]. The NTLM message is then encapsulated as defined previously and sent to the server.

The state of the client is changed to inside_authentication.
