	// CompleteChallenge is invoked with the headers from a successful server response
	// received after having handled one or more challenges.
	// Returns an error if the handler does not consider the challenge/response interaction complete.
	CompleteChallenge(requestURL string, headers http.Header) error
	// Release gives the handler a chance to release any resources held during a challenge/response sequence.

	// It may be invoked multiple times. If an error is returned, InitSecContext and IsComplete are not called, but Release() is.
	Load() error
	// InitSecContext returns the response token for a Negotiate challenge token from a given URL,
	// or an error if no response token could be obtained or the incoming token is invalid.
	InitSecContext(requestURL string, challengeToken []byte) (tokenToSend []byte, err error)
	// IsComplete returns true if the negotiator is satisfied with the negotiation.
	// This typically means gssapi returned GSS_S_COMPLETE to an initSecContext call.
	IsComplete() bool
