> Issue Type: Bug

> Priority: Major

> We are trying to modify the sasl jaas configurations for the kafka broker
> runtime using the dynamic config update functionality using the
> kafka-configs.sh script. But we are unable to get it working.
> Below is our command:
> ./kafka-configs.sh --bootstrap-server localhost:9092 --entity-type brokers
> --entity-name 59 --alter --add-config 'sasl.jaas.config=KafkaServer \{\n
> org.apache.kafka.common.security.plain.PlainLoginModule required \n
> username=\"test\" \n password=\"test\"; \n };'
>
> command is exiting with error:
> requirement failed: Invalid entity config: all configs to be added must be in
> the format "key=val".
>
> we also tried below format as well:
> kafka-configs.sh --bootstrap-server localhost:9092 --entity-type brokers
> --entity-name 59 --alter --add-config
> 'sasl.jaas.config=[username=test,password=test]'
> command does not return but the kafka broker logs prints the below error
> messages.
> org.apache.kafka.common.security.authenticator.SaslServerAuthenticator - Set
> SASL server state to FAILED during authentication"}}

> 1. If one has SASL enabled and with a single listener, how are we supposed to

> 2. can anyone point us out to some example commands for modifying the sasl
