Hello All, I am trying to set up Kafka(v3.6.1) to use mTLS authentication/authorization for *inter broker* communication but currently server.properties doesn't allow me to set a key store that contains client private key/certificate. I did try supplying a keystore to Kafka that contains both TLS server and client private key entries but that doesn't seem to work.
Essentially what I am looking for is: ```java listeners=BROKER://:21500,CONTROLLER://:21501 advertised.listeners=BROKER://localhost:21500 listener.security.protocol.map=BROKER:SSL,CONTROLLER:SSL security.protocol=SSL ssl.client.auth=required ssl.enabled.protocols=TLSv1.2,TLSv1.3 ssl.keystore.type=JKS ssl.keystore.password=changeit ssl.keystore.location=/tmp/kafka/pki/server.jks ############ Is something like this following possible? <-------------------- ssl.client.keystore.type=JKS ssl.client.keystore.password=changeit ssl.keystore.location=/tmp/kafka/pki/client.jks ``` I am able to configure both the producer and consumer to use mTLS authentication to talk to the Kafka cluster but for inter broker communication I am not able to supply the broker TLS client certificates in the properties. Any help on this is appreciated! Thank you in advance. Regards, Krishna V
