> We are trying to use kafka-configs script to modify the sasl jaas configurations, but unable to do so.
> Command used:
> ./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 };'
> error:
> requirement failed: Invalid entity config: all configs to be added must be in the format "key=val".
> command 2:
> kafka-configs.sh --bootstrap-server localhost:9092 --entity-type brokers --entity-name 59 --alter --add-config 'sasl.jaas.config=[username=test,password=test]'
> output:
> command does not return , but kafka broker logs below error:
> DEBUG", "neid":"kafka-cfd5ccf2af7f47868e83471a5b603408", "system":"kafka", "time":"2021-03-23T08:29:00.946", "timezone":"UTC", "log":\{"message":"data-plane-kafka-network-thread-1001-ListenerName(SASL_PLAINTEXT)-SASL_PLAINTEXT-2 - org.apache.kafka.common.security.authenticator.SaslServerAuthenticator - Set SASL server state to FAILED during authentication"}}

> We have below issues:
>  1. If one installs kafka broker with SASL mechanism and wants to change the SASL jaas config via kafka-configs scripts, how is it supposed to be done ? Is one supposed to provide kafka-configs script credentials to get authenticated with kafka broker ?
>  does kafka-configs needs client credentials to do the same ? 
>  2. Can anyone point us to example commands of kafka-configs to alter the sasl.jaas.config property of kafka broker. We do not see any documentation or examples for the same.
