             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.
