JAAS uses its own configuration file. The following are the different forms of SASL: SASL PLAINTEXT, SASL SCRAM, SASL GSSAPI, SASL Extension, SASL OAUTHBEARER. 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. /**A consumer is instantiated by providing a {@link java.util.Properties} object as configuration, and a * key and a value {@link Deserializer}. SASL can be enabled individually for each listener. Implements authentication using Salted Challenge Response Authentication Mechanism (SCRAM). I believe that my application.yml is not configure correctly so please advice and help. To make this post easy and simple, I choose to modify the the bin/kafka-run-class.sh, bin/kafka-server-start.sh and bin/zookeeper-server-start.sh to insert those JVM options into the launch command.. To enable SASL authentication in Zookeeper and Kafka broker, simply uncomment and edit the config files config/zookeeper.properties and config/server.properties. 2020-10-02 13:12:14.996 INFO 13586 --- [           main] o.a.k.clients.consumer.ConsumerConfig   : ConsumerConfig values: key.deserializer = class org.apache.kafka.common.serialization.StringDeserializer, partition.assignment.strategy = [org.apache.kafka.clients.consumer.RangeAssignor], value.deserializer = class org.apache.kafka.common.serialization.StringDeserializer. Digest-MD5). The log helps replicate data between nodes and acts as a re-syncing mechanism for failed nodes to restore their data. After you run the tutorial, view the provided source code and use it as a reference to develop your own Kafka client application. A path to this file is set in the ssl.keystore.location property. ( Log Out /  2020-10-02 13:12:14.918 INFO 13586 --- [           main] o.a.k.c.s.authenticator.AbstractLogin   : Successfully logged in. In the last section, we learned the basic steps to create a Kafka Project. We use two Data Hubs, one with a Data Engineering Template, and another with a Streams Messaging template. In two places, replace {yourSslDirectoryPath} with the absolute path to your kafka-quarkus-java/ssl directory (or wherever you put the SSL files). CloudKarafka uses SASL/SCRAM for authentication, there is out-of-the-box support for this with spring-kafka you just have to set the properties in the application.properties file. So, how do we use SASL to authenticate with such services? Apache Kafka® brokers support client authentication using SASL. Pre-requisite: Novice skills on Apache Kafka, Kafka producers and consumers. Intro Producers / Consumers help to send / receive message to / from Kafka SASL is used to provide authentication and SSL for encryption JAAS config files are used to read kerberos ticket and authenticate as a part of SASL Kafka Version used in this article :0.9.0.2 Console Producers and Consumers Follow the steps given below… The certificates should have their advertised and bootstrap addresses in their Common Name or Subject Alternative Name. In our project, there will be two dependencies required: Kafka Dependencies; Logging Dependencies, i.e., SLF4J Logger. This Mechanism is called SASL/PLAIN. Listener without encryption but with SASL-based authentication. Let's now see how can we configure a Java client to use SASL/PLAIN to authenticate against the Kafka Broker. The SASL/PLAIN binding to LDAP requires a password provided by the client. The kafka-configs.sh tool can be used to manage them, complete ${kafka-home}/config/server.properties file looks like below, The above command will fails as it do not have create permissions, Similarly give permissions to producer and consumer also, Now from spring-boot application  using camel producer/consumer. Red Hat AMQ Streams is a massively-scalable, distributed, and high-performance data streaming platform based on the Apache ZooKeeper and Apache Kafka projects. Creating Kafka Producer in Java.
