Please keep the discussion on the mailing list rather than commenting on the wiki (wiki discussions get unwieldy fast).

Motivation

KIP-425 provides the Kafka Log4j appender with SASL based authentication to allow logging to SASL enabled Kafka clusters. Currently credentials must be defined statically within the JAAS configuration similar to DIGESt-MD5 in Zookeeper and older versions of Kafka. KIP-86 has since been adopted giving Kafka the ability to obtain credentials from alternative credentials stores.  This KIP intends to expose the configuration properties used to enable this functionality in the underlying client.
