IT24150: IT IS NOT POSSIBLE TO SET GSSAPI WHEN USING THE KAFKA NODES

APAR status

• Closed as program error.

Error description

• In order to use the Kafka Nodes with Kerberos authentication it
  is required to set the SASL mechanism to GSSAPI, however the
  nodes will attempt to autoamtically set the SASL mechanism
  based on the security method. Since the default is username /
  pasword authentication this prevent the use of Kerberos.
  
  This APAR introduces a new environment variable
  MQSI_KAFKA_SASL_MECHANISM when set in the Integration node's
  profile environment the value will be passed through to the
  "sasl.mechanism" property of the Kafka client. In order to use
  Kerberos the following setting should be used:
  MQSI_KAFKA_SASL_MECHANISM=GSSAPI

Problem conclusion

• This APAR introduces a new environment variable
  MQSI_KAFKA_SASL_MECHANISM which when set in the Integration
  node's profile environment, the value will be passed through to
  the "sasl.mechanism" property of the Kafka client. In order to
  use Kerberos the following setting should be used:
  MQSI_KAFKA_SASL_MECHANISM=GSSAPI
  
  This APAR also introduces the ability to pass a Kafka properties
  file directly in to the Node. For a producer you can set the
  fully qualified path to the properties file in MQTT configurable
  service or policy for a consumer the fully qualified path should
  be set in property2.
  
  The properties file itself can include any properties recognised
  by the Kafka client including the SASL Mechanism and the
  requires jaas.conf stanza.
