JAAS is also used for authentication of connections between Kafka and ZooKeeper. Let's suppose we've configured Kafka Broker for SASL with PLAIN as the mechanism of choice. SCRAM authentication in Kafka consists of two mechanisms: SCRAM-SHA-256 and SCRAM-SHA-512. Implements authentication using Salted Challenge Response Authentication Mechanism (SCRAM). Let's now see how can we configure a Java client to use SASL/PLAIN to authenticate against the Kafka Broker. Podcast 281: The story behind Stack Overflow in Russian.

The certificates should have their advertised and bootstrap addresses in their Common Name or Subject Alternative Name. If using streams then its recommended to enable stream caching. In our project, there will be two dependencies required: Kafka Dependencies; Logging Dependencies, i.e., SLF4J Logger. Running locally It is defined to be mechanism-neutral: the application that uses the API need not be hardwired into using any particular SASL mechanism. This topic only uses the acronym “SSL”. Set the ssl.keystore.location option to the path to the JKS keystore with the broker certificate. *

* Note: after creating a {@code KafkaConsumer} you must always {@link #close()} it to avoid resource leaks. Join the DZone community and get the full member experience. SASL/SCRAM servers using the SaslServer implementation included in Kafka must handle NameCallback and ScramCredentialCallback.The username for authentication is provided in NameCallback similar to other mechanisms in the JRE (eg.

In this usage Kafka is similar to Apache BookKeeper project. Set the ssl.keystore.password option to the password you used to protect the keystore. Kafka uses the Java Authentication and Authorization Service (JAAS) for SASL configuration. Listener without any encryption or authentication. Both Data Hubs were created in the same environment. This Mechanism is called SASL/PLAIN. This is done using the sasl.enabled.mechanisms property. SASL authentication is configured using Java Authentication and Authorization Service (JAAS). See you with another article soon. Kafka uses the JAAS context named Kafka server. 1. To enable SCRAM authentication, the JAAS configuration file has to include the following configuration: Sample ${kafka-home}/config/kafka_server_jass.conf file, And in server.properties file enable SASL authentication, Create ssl-user-config.properties in kafka-home/config, User credentials for the SCRAM mechanism are stored in ZooKeeper. In kafka environment, I had changed some parameters in server.properties file for enabling SASL and then created the jaas file for kafka. To enable it, the security protocol in listener.security.protocol.map has to be either SASL_PLAINTEXT or SASL_SSL. While implementing the custom SASL mechanism, it may makes sense to just use JAAS. Edit kafka_client_jaas.conf file (under /usr/hdp/current/kafka-broker/conf), Edit kafka-env.sh file (under /usr/hdp/current/kafka-broker/conf), The trust store must contain the organizations root CA, Messages entered in the producer console would be received in the consumer console. The SASL section defines a listener that uses SASL_SSL on port 9092. In two places, replace {yourSslDirectoryPath} with the absolute path to your kafka-quarkus-java/ssl directory (or wherever you put the SSL files).
