Hello,
I have noticed that a while ago, Microsoft has added the ability to add external users (that is, non-Windows accounts) into roles in SSAS tabular models, as per the screenshot below:

We have an on-prem SQL Server 2016 (latest SP) with a tabular model that we access via the on-prem data gateway. As a test for row-based level security, we are trying to send an external user as the effective user ID, but that does not seem to work. Basiclly I added a user (e.g. joe@blogs.com) and sending that user as the effective user id returns an access denied error. If we pass an existing Windows account (i.e. an Active Directory user) then it works as expected.
I wonder if Power BI would ever work with external users specified in an SSAS tabular model?
Regards,
P.
