Kafka Authentication + Authorization

Dear Users,

Few questions regarding authentication

1- in case of implementation of SASL/SCRAM without SSL with below param

listeners=SASL_PLAINTEXT://apache-kafka.abc.com:9090
security.inter.broker.protocol=SASL_PLAINTEXT
sasl.mechanism.inter.broker.protocol=SCRAM-SHA-256
sasl.enabled.mechanisms=SCRAM-SHA-256

2- zookeeper is still not secured

3- New broker gets added without any jaas file in existing broker config.

Am i missing something? New borker should fail with failed Authentication
message ?


4- client is working properly .Client does not work unless client property
is passed

Regards,
Rohit Garg
