[jira] [Created] (KAFKA-21257) Document tokenless OAUTHBEARER login for validate-only brokers

Chia-Ping Tsai created KAFKA-21257:
--------------------------------------

             Summary: Document tokenless OAUTHBEARER login for validate-only brokers
                 Key: KAFKA-21257
                 URL: https://issues.apache.org/jira/browse/KAFKA-21257
             Project: Kafka
          Issue Type: Improvement
            Reporter: Chia-Ping Tsai
            Assignee: Chia-Ping Tsai


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 🙂
