IOT Streams, Kafka With Kerberos

We have a Kafka instance that utilizes Kerberos for authentication, and I want to set up an IOT Stream to push property data to it. I am successfully using Kerberos auth for a database connection from my Thingworx server (RHEL, Thingworx v10.1.1).  Do the Queue Providers support Kerberos authentication at this point?

The Help Center documentation doesn’t provide much guidance on what values I should use in the Configuration of my Queue Provider.  It also seems like the only authentication available is username/password-based.  After some research I tried using “SASL_SSL” for Security Protocol and “GSSAPI” for SASL Mechanism, but I get this error: Save failed: Failed to connect to [MyQP]. Reason: Failed to create new KafkaAdminClient

Any suggestions on getting the Queue Provider to utilize Kerberos authentication for connecting to my Kafka instance?
