[jira] [Resolved] (KAFKA-20067) Config synonyms are not returned for listener overrides

     [ https://issues.apache.org/jira/browse/KAFKA-20067?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Mickael Maison resolved KAFKA-20067.
------------------------------------
    Resolution: Invalid

Upon further checking per listener configurations need to have the listener name in the config listener.name.<NAME>.<CONFIG>. A comment in DynamicBrokerConfig mentions configs using the listener.name.<CONFIG> format but that seems invalid.

I'll adjust the comment

> If a user set listener.name.connections.max.reauth.ms and describe its synonyms, the synonyms returned are only listener.name.connections.max.reauth.ms. It should also contain connections.max.reauth.ms.
> The issue is that DynamicBrokerConfig.brokerConfigSynonyms() does not handle listener overrides correctly.
