> There is no official documentation about tokenless login in authentication-using-sasl.md. Some users (see KAFKA-21143) rely on {{OAuthBearerUnsecuredLoginCallbackHandler}} as a workaround for validate-only brokers, and KAFKA-21221 will raise a discussion to provide an official handler for it.
> Since KAFKA-21221 needs a KIP cycle, it would be better to document the current behavior first 🙂
