@sumitPanda, is this supported in Free Edition Databricks? i.e. connecting to ADLS via UC. I think that's part of the constraints at play here. 

Completely agree, in production, UC is the way. In fact, we'd normally not need to connect to ADLS if we're using Azure Databricks (and not using external tables). It does depend on the use case, of course. 

All the best,
