## B.5 User Identity Plus Passcode Association Profile

An implementation that supports the User Identity plus Passcode Association Profile shall send/accept the User Identity association negotiation sub-item, for User-Identity-Type of 2. If a positive response is requested, the association acceptor implementation shall respond with the association response sub-item. The passcode information shall be made available to internal or external authentication systems. The user identity shall be authenticated by means of the passcode and the authentication system. If the authentication fails, the association shall be rejected.

The user identity from the Primary-field shall be used within the implementation as the user identification. Such uses include recording user identification in audit messages.
