Hi @Anonymous ,

So far, I haven't been able to get it to work. However, I really appreciate @Prabakar's answer and your follow-up. 

I'm still interpreting @Prabakar's wise advice; however, I think it mostly doesn't apply to this situation, as I'm using a brand new instance through Partner Connect, which defaults to per-user connections. Since the token is generated by Databricks and is a Personal Access Token, there is no "Can attach to", "Contributor" role, or firewall settings that I can see. As the primary admin user on the Workspace, I have all the permissions -- and FiveTran is (theoretically) is using my account directly through the Personal Access Token. 

I'm sure I'm just missing something obvious here, as this account is entirely fresh out of the box. It may be that I need to set up the connection from FiveTran manually, by following the guide and creating a Service Principal manually. But I would love any guidance you might have so that I can use Partner Connect. 🙂
