1.7 Versioning and Capability Negotiation
This document covers versioning issues in the following areas:
Security and Authentication Methods: The Telnet: NTLM Authentication Protocol supports the NTLMv1 and NTLMv2 authentication methods, as specified in [MS-NLMP].
Capability Negotiation: The Telnet: NTLM Authentication Protocol does not support negotiation of the NTLM Authentication Protocol version to use. Instead, the NTLM Authentication Protocol version is required to be configured on both the client and the server prior to authentication. NTLM Authentication Protocol version mismatches are handled by the NTLM Authentication Protocol implementation, and not by the Telnet: NTLM Authentication Protocol.
