Hi Alexander, I also went through the docs and indeed it contains outdated information which can prevent you from setting up Kafka with SSL. I have opened KAFKA-21329 <https://issues.apache.org/jira/browse/KAFKA-21329> to work on updating the docs. It likely won't reach the official docs site until the release of Kafka 4.5 which is still months away. In the meantime you can check out my patch at kafka/pull/23907 <https://github.com/apache/kafka/pull/23907> and hopefully it can unblock you in your SSL setup work. Of course any feedback is welcome on the updated steps :)
