Hi all, I would like to start a discussion on KIP-1390: Add a tokenless login callback handler for SASL/OAUTHBEARER <https://cwiki.apache.org/confluence/x/qAKWGw>
A broker that only validates OAuth tokens does not need its own token, but today it relies on the internal OAuthBearerUnsecuredLoginCallbackHandler to log in without one. This KIP proposes a new OAuthBearerTokenlessLoginCallbackHandler to support tokenless login officially. Best, Ming-Yen
