----------------------------------------

             Summary: kafka-configs.sh does not work while changing the sasl jaas configurations.
                 Key: KAFKA-12528
                 URL: https://issues.apache.org/jira/browse/KAFKA-12528
             Project: Kafka
          Issue Type: Bug
          Components: admin, core
            Reporter: kaushik srinivas


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"}}
{"type":"log", "host":"kf-kaudynamic-0", "level":"INFO", "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.network.Selector - [SocketServer brokerId=1001] Failed authentication with /127.0.0.1 (Unexpected Kafka request of type METADATA during SASL handshake.)"}}

 

1. If one has SASL enabled and with a single listener, how are we supposed to change the sasl credentials using this command ?

2. can anyone point us out to some example commands for modifying the sasl jaas configurations ?
