Is there any sample for kerberos connection?

While trying Consumer with Kerberos, I could not get it work (I tried Kafka official consumer-console.sh and it is working as normal). While using node-rdkafka, the application hang and there is no error or connect ready emit. Here is my Consumer log:

KafkaConsumer {
  _events:
   { ready: [Function],
     disconnected: [Function],
     'event.error': [Function] },
  _eventsCount: 3,
  _maxListeners: undefined,
  _client: KafkaConsumer {},
  metrics: {},
  _isConnected: false,
  errorCounter: 0,
  _metadata: {},
  globalConfig:
   { debug: 'all',
     'group.id': 'my_group_id',
     'metadata.broker.list':'host1:port,host2:port,host3:port',
     'security.protocol': 'sasl_plaintext',
     'sasl.kerberos.kinit.cmd':
      'kinit -k -t /my.keytab ${principal}',
     'sasl.mechanisms': 'GSSAPI',
     'sasl.kerberos.keytab': '/my.keytab',
     'sasl.kerberos.service.name': 'kafka',
     'sasl.kerberos.principal': '${principal',
     'sasl.kerberos.min.time.before.relogin': 60000,
     'enable.auto.commit': false,
     connect_cb: [Function: connect_cb],
     rebalance_cb: [Function] },
  topicConfig: { 'auto.offset.reset': 'earliest' },
  _consumeTimeout: 1000 }

I have my custimized krb5.conf which is easily set if using Java: `-Djava.security.krb5.conf=/my/krb5.conf`

I set it using environment variable `KRB5_CONFIG` but still not work.

Here’s a working sample working with Secured Kafka Cluster

kafkacat -b '<Broker_Hostname>:<Broker_Listen_Port>' -L \
-X security.protocol=sasl_plaintext \
-X sasl.kerberos.keytab='kafka.service.keytab' \
-X sasl.kerberos.service.name=kafka \
-X sasl.kerberos.principal='kafka/<Broker_Hostname>@<REALM>' \
-X sasl.kerberos.kinit.cmd="kinit -kt <App_KeytabName> <App Keytab Principal>"
-t <TopicName>```

**Note**: Ensure the App Account has consume and describe access to Topic
