wildfly clients gives Unsupported Call Back
Hi ,
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 server . I have set up all the required configuration (Config Section below)
The SASL_JAAS_CONFIG 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 THE CLIENT CALL BACK IS CLIENTCREDENTIAL INSTEAD OF OAuthBearerTokenCallback. The saslclient is getting set as AbstractSaslClient instead of OAuthBearerSaslClient.
Can I get any pointers on this one ?
