Hi all, I have submitted KIP-282 to add the listener name to the authentication context: https://cwiki.apache.org/confluence/display/KAFKA/KIP-282%3A+Add+the+listener+name+to+the+authentication+context
This is a very minor KIP to simplify identifying the source of a connection instead of relying on parsing the client address when building Principals. Feedback and suggestions are welcome! Thanks
