Hello, I have a rather odd issue that I think this KIP might fix but wanted to check. I have a kafka setup using SASL/Kerberos and when a broker dies in aws a new one is created using the same name/id. The Kerberos credentials however are different on the new instances and existing brokers/consumers/producers continue to try using the stored credentials for the old instance on the new instance which fails until everything is restarted to clear out stored credentials. My understanding is this KIP would make it so Re-Authenticate will clear out bad stored credentials. I am not sure if the re-authentication process would kick of when something fails with bad credential errors though.
