Additional context

connecting to existing kafka with sasl authentication

[angeloimm]

this is how I wrote my values.yaml:

   kafka:
     clusters:
       - name: "MyBrokerName"
         bootstrapServers: my_broker_url:9092
         properties:
           security.protocol: "SASL_PLAINTEXT"
           sasl.mechanism: "SCRAM-SHA-256"        
           sasl.jaas.config: "org.apache.kafka.common.security.scram.ScramLoginModule required username=\u0022MY_BROKER_USERNAME\u0022 password=\u0022MY_BROKER_PWD\u0022;"

What is the status of this? Is there some workaround to be able to connect to broker which requires SCRAM-SHA-512 authentication?

FYI: The below, redacted, configuration works for me. You can probably close this issue.

- name: delivery-test
        bootstrapServers: test-kafka-external-boostrap.example.com:9094,test-kafka-external-0.example.com:9094,test-kafka-external-1.example.com:9094,test-kafka-external-2.example.com:9094
        properties:
          security.protocol: SASL_SSL
          sasl.mechanism: SCRAM-SHA-512
          sasl.jaas.config: org.apache.kafka.common.security.scram.ScramLoginModule required username="USERNAME_HERE" password="PASSWORD_HERE";
