Thank you for replying with your questions. Yes, this error appears when clicking on the "Test Connection" button for both the "default" (ports 3268 or 3269) and additional "domains" (both ports 389 or 636).

In some other online research, I found info that our domain controllers require java. Do you know if that is correct? Also, I found that you must have both a "default" and additional domain with both a FQDN entries and the other with friendly names. We applied both of these workarounds on our Test domain and now it's working there.
