Is it currently possible to honour row-level security with the XMLA endpoint, we're pulling data to present to end users but the cubes require the effective username to be supplied, trying the ChangeEffectiveUser(.. call returns the following error
"value of the 'EffectiveUserName' XML for Analysis property is not valid."
The documents here implies that it's not possible to provide the effectiveUser..
"Operations that require Analysis Services server admin permissions (rather than database admin) such as server-level traces and user impersonation using the EffectiveUserName connection-string property are not supported in Power BI Premium at this time."
Is this true? If so is it likely to change soon?
We've tried passing the UPN by using "ChangeEffectiveUser" but we're getting the error (mentioned in my first post)
Value of the 'EffectiveUserName' XML for Analysis property is not valid.
It does mention in the link provided that it isnt' support ".. in Power BI Premium at this time"
Is this the case?
What are you trying to do with the XMLA end point?
You would need to log into the XMLA end point, and as long as you are in a defined role with the correct permissions you should be able to query the cube.
Cheers for your response.
We're calling the XMLA Endpoint in Power Bi Premium with a service principal from an AppService in Azure - It's a intranet application we have the users UPN in context of each call we just return data to the front-end web application. (that's all working correctly)
We have a seperate system that manages the RLS , but for it to function we need to include the UPN in the request , when we try including the user UPN we got the, perviously mentioned, error!
Looking at the documentation it seems that we should be able to use the EffectiveUserName element.
I'm reading conflicting information; it should work if we grant the principal server rights, or; it's not supported in PBI Premium -
