A user can specify the authentication login module through sasl.jaas.config Kafka client property. It can be configured through an external properties file or by using a Kafka policy. However, all the values of sasl.jaas.config may not take effect and the user will see the Kafka nodes failing to connect to the Kafka server. In the reported case, the customer was trying to connect to an Amazon MSK server protected with IAM policy and they were using the following properties file on the KafkaConsumer node. . ssl.truststore.location=<PATH_TO_TRUST_STORE_FILE> security.protocol=SASL_SSL sasl.mechanism=AWS_MSK_IAM sasl.jaas.config=software.amazon.msk.auth.iam.IAMLoginModule required; sasl.client.callback.handler.class=software.amazon.msk.auth.iam .IAMClientCallbackHandler
