----------------------------------------
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"}}

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 ?
