Row Level Security and Licensing

[dlandry]

I am implementing row level security based on UserID.  I've created a measure (User = Username()) and then created a role called MyAssignments ([User] = Username()).  This seems to be working fine except for anyone outside the organization.  When I share this with someone outside the organization Power BI will not allow me to add that persons email address to the MyAssignments role.

Can someone explain:

1. What are the licensing requirements for internal users and external users when using role based security?  I'm understanding that all the internal users would have to have a power bi pro license which seems riduculous because all they are doing is viewing the reports they don't create any visualizations etc.
2. Is there a different way to do this other than using role based security?
3. Can external users be added to role based security?  If so how is that done?  If not, do all my external users have to have a doman Office 365 account and be given access to the Power BI application.

The request is simple just show only report items related to that user but when I tested it with one of the users it prompted them to get a 60 day pro license. 

Thanks for your help

Any report that uses Pro features, users that view it must also have a Pro license. RLS is a Pro feature.

Here is a blog post on a different approach to RLS that may or may not help:

As for external users, one way that I have gotten around this is to invite external users to a SharePoint site. In this way, they create a "stub" account in your Active Directory that is tied to their external Microsoft "Live" account. You can then add that "stub" account as one of your members in your RLS group.

But these stub accounts need a Power Bi Pro licence aswell, or am I wrong?
