Expand description

Handles SASL authentication.

The lifecycle of an authenticator consists of:

The initial_response function will be called. The initial return value will be sent to the server to initiate the handshake.
The server will respond to each client response by either issuing a challenge or indicating that the authentication is complete (successfully or not). If a new challenge is issued, the authenticator’s evaluate_challenge function will be called to produce a response that will be sent to the server. This challenge/response negotiation will continue until the server responds that authentication is successful or an error is raised.
On success, the handle_success will be called with data returned by the server.
