Error connecting to Azure Analysis Services from Power BI Report Server

I have created a report in Power BI Desktop (RS edition) and connected it to our Azure Analysis Services Model.

I connected using my Microsoft Account (AAD?) and can run the report without issue.

However, once it's published to our Report Server, when I access it I receive the error:

 

Couldn't connect

Nope, missed that 🙂

We've had to move our model in to SSAS on-prem now in.

Hi, @RickyRhys 

 

Yes, Try to modify the authentication method to basic authentication on the report server. See if this works.

Hi Janey,

Thanks for your reply.

I am able to connect with Basic Authentication without issue. However, we have RLS enabled on our AAS Model so I need the logged in user to connect as themselves, not the hardcoded user in the report datasource Basic Authentication.

Is this possible?

Hi, @RickyRhys 

 

If you use desktop for service, You can do it. But I think it’s hard to do it in the report server. Report server is on-premises solution for reporting.

Hi Janey,

According to the Microsoft Documentation, SQL Server Analysis Services is a supported datasource for Power BI Report Server.

I still have this issue as it's imperative that we can use Row-Level security for these reports.

Using a hard-coded Username and Password with Basic Authentication is not secure for us.
Any help greatly appreciated.

Hi, @RickyRhys 

 

Did you look down?

If you have new questions, you can re-post a thread, which will make the thread active again and more engineers will participate. I'm no longer in charge of the RS threads, there will be more professional engineers in charge of you.
