Hi guys,   I have a Kafka cluster and want to enable SASL_SSL without Kerberos. Is it possible?   What I changed in kafka.properties:   listeners=PLAINTEXT://kafkatest03.loc:9092, SSL://kafkatest03.loc:9093, SASL_SSL://kafkatest03.loc:9094, SASL_PLAINTEXT://kafkatest03.loc:9095 advertised.listeners=PLAINTEXT://kafkatest03.loc:9092, SSL://kafkatest03.loc:9093, SASL_SSL://kafkatest03.loc:9094, SASL_PLAINTEXT://kafkatest03.loc:9095 ssl.enabled.protocols=TLSv1.2,TLSv1.1,TLSv1 sasl.enabled.mechanisms=SCRAM-SHA-256 sasl.mechanism.inter.broker.protocol=SCRAM-SHA-256 authorizer.class.name=kafka.security.auth.SimpleAclAuthorizer ssl.keystore.location=... ssl.keystore.password.generator=... ssl.key.password.generator=... ssl.truststore.location=... ssl.truststore.password.generator=...   Added to broker_java_opts:   -Djava.security.auth.login.config=/etc/kafka/kafka_server_jaas.conf KafkaServer { org.apache.kafka.common.security.scram.ScramLoginModule required username="admin" password="admin"; };     When I set security.inter.broker.protocol to PLAINTEXT everything is working and client can auth wirh SASL_SSL using SCRAM-SHA-256, but ACL is not working.   According to this: https://github.com/wurstmeister/kafka-docker/issues/218 we need to enable security.inter.broker.protocol=SASL_SSL, but it throws an error:   security.inter.broker.protocol can not be set to SASL_SSL, as Kerberos is not enabled       Thanks ...
