I have it working with both ISAPI and BonCode connectors. ARR method wouldn't work unfortunately since the CF container is running on Linux and can't do WinAuth. It has to be done through these connectors.
The problem is more with the Docker image than the connector. Image's state gets messed up and doesn't behave normally. The connector starts working after a couple of AppPool recycles. BonCode works out of the box.
Clik here to view.
