3.2.5.2 Receiving an NNTP_AUTH_NTLM_Blob_Command Message
The expected state is inside_authentication.
When a server receives this message, it MUST de-encapsulate the message, obtain the embedded NTLM message, and pass it to the NTLM software. The NTLM software MUST then take one of the following actions:
Report success in processing the message and return an NTLM message to continue the authentication.
Report that authentication completed successfully.
Report that the authentication failed due to a bad user name or password, as specified in [MS-NLMP].
Report that the authentication failed, which could be due to some other software error or message corruption.
