Unable to connect to a Power BI Workspace (Premium) on SQL Server Management Studio

[Mitchvdd]

I am unable to connect to a Power BI Workspace (Premium Capacity). The XMLA read / write is enabled, so that shouldn't be a problem.

I get the following error when I try to connect: "The integrated security 'Claims Token' is not supported for native connections. (Microsoft.AnalysisServices.AppLocal.AdomdClient)"

Does anyone have an idea how this can be solved?

The problem was that I still had SSMS 17 running and to be able to connect to a Power BI Workspace you need at least SSMS 18. So that solved the problem!

What other authentication types have you tried? Seems to not like the one you chose.

I tried 'Active Directory - Password' & 'Active Directory - Universal with MFA support' and both not work...
