azure - Access ADLS2 from PowerBI service with Guest user credentials

Question

I've tried to give access to an Active Directory external user (with Guest type). ADLS2 enables to use of such users for RBAC or ACL tables.

But when I tried to access ADLS2 as a guest user from the Power BI service I've got an error: "The credentials provided for the AzureDataLakeStorage source are invalid.":

Failed to update data source credentials: The credentials provided for the AzureDataLakeStorage source are invalid. (Source at https://hasodl2westeurope.dfs.core.windows.net/mycontainer/samplefolder.)

Is this behavior a bug or a feature?

Is a way to access ALDS2 as a Guest user?

Answer 1

ADLS only supports AD users from the same tenant, not guest users - source.
