1.7 Versioning and Capability Negotiation

This specification covers versioning issues in the following areas:

  • Supported Transports: This protocol uses multiple RPC protocol sequences as described in section 2.1.

  • Protocol Versions: The EMSMDB interface has a single version number of 0.81 and has been extended by adding methods as specified in section 3.1. The AsyncEMSMDB interface has a single version number of 0.01.

  • Security and Authentication Methods: This protocol supports the following authentication methods: NT LAN Manager (NTLM) Authentication Protocol, Kerberos, and Negotiate. These authentication methods are described in sections 3.1.3 and 3.3.3.

  • Capability Negotiation: The Ethernet protocol does not support negotiation of the interface version to use. Instead, an implementation is configured with the interface version to use, as described in this specification.
