             Summary: Multi-module support for JAAS config property
                 Key: KAFKA-8234
                 URL: https://issues.apache.org/jira/browse/KAFKA-8234
             Project: Kafka
          Issue Type: Improvement
            Reporter: Gabor Somogyi


I've tried to add multi-modules to JAAS config property but its not supported at the moment:
{code:java}
Exception in thread "main" org.apache.kafka.common.KafkaException: Failed create new KafkaAdminClient
	at org.apache.kafka.clients.admin.KafkaAdminClient.createInternal(KafkaAdminClient.java:370)
	at org.apache.kafka.clients.admin.AdminClient.create(AdminClient.java:52)
	at com.kafka.delegationtoken.consumer.SecureKafkaConsumer$.main(SecureKafkaConsumer.scala:96)
	at com.kafka.delegationtoken.consumer.SecureKafkaConsumer.main(SecureKafkaConsumer.scala)
Caused by: java.lang.IllegalArgumentException: JAAS config property contains 2 login modules, should be 1 module
	at org.apache.kafka.common.security.JaasContext.load(JaasContext.java:95)
	at org.apache.kafka.common.security.JaasContext.loadClientContext(JaasContext.java:84)

	at org.apache.kafka.clients.admin.KafkaAdminClient.createInternal(KafkaAdminClient.java:346)
	... 3 more
{code}
I wanted to implement a fallback scenario with sufficient LoginModule flag but the missing multi-module support makes in impossible.
