> 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:

> 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 ?
> 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.
