Summary: Exception while connecting from kafka client consumer producers deployed in a wildfly context to a kafka broker implementing OAUTHBEARER sasl mechanism Key: KAFKA-13411 URL: https://issues.apache.org/jira/browse/KAFKA-13411 Project: Kafka Issue Type: Bug Components: security Affects Versions: 3.0.0 Environment: Windows, Linux , Wildfly Application server Reporter: Shankar Bhaskaran Fix For: 3.0.1 I have set up a Kafka cluster on my linux machine secured using keycloak (OAUTHBEARER) Mechanism. I can use the Kafka Console Consumers and Producers to send and receive messages. I have tried to connect to Kafka from my consumers and producers deployed as module on the wildfly App serve (version 19, java 11) . I have set up all the required configuration (Config Section at the bottom) . The SASL_JAAS_CONFIG provided as consumerconfig option has the details like (apache.kafka.common.security.oauthbearer.OAuthBearerLoginModule required LoginStringClaim_sub='kafka-client'); I am able to get authenticated with the broker , but in the client callback I am getting an Unsupported Callback error . I have 3 modules in wildfly 1) kafka producer consumer code dependent on the 2) oauth jar (for logincallbackhandler and login module) dependent on the 3) kafka-client jar (2.8.0)] I can see that the CLIENT CALL BACK IS CLIENTCREDENTIAL INSTEAD OF OAuthBearerTokenCallback. The saslclient is getting set as AbstractSaslClient instead of OAuthBearerSaslClient.
