Is there any update on this feature request? OAuth still seems not to be working with Azure Blob Storage... Configuration works fine for ADLS gen 2, but for Azure Blob Storage still only SAS and Account key seems to be working.

Hi @KVNARK .​ ,You can use the service principle in the azure active directory to grant specific access to that app and use that app credentials to create a new mount point.That will help you to give specific storage permission to users.

that is certainly an invalid path, as the error shows.with %fs ls /mnt you can show the directory structure of the /mnt directory, assuming the blob storage is mounted.if not, you need to define the access ( URL etc.)

try importing argv from sys. Then if you have the parameter added correctly in DataFactory you could get it in your python script typing argv[1] (index 0 is the file path).
