In a sense this is a follow up question to my previous one: SQL Server with DB Visualizer

So as suggested by the user @AlwaysLearning, if one tries to use Windows Authentication, then jTDS driver is the way to go.

Now I am using Kafka connect with SQL Server, the panic thing is about the configuration, as the following shown.

For the connnection.url, I use jTDS. However, as it is about Windows Authentication, I did not enter "connection.user": "..." and "connection.password": "..." as it usually does. But then I ended up with error that

java.io.IOException: GSS Failed: Invalid name provided (Mechanism level: KrbException: Cannot locate default realm).

How do I overcome this difficulty?

After some struggling to look for solutions around, I feel like the issue is about working Windows Authentication with Docker. At least my Kafka Connect is hosted in Docker. But I really have no idea how to solve this issue.
