Fabric Warehouse - Service Principal permissions on Data warehouse

[arnefromaus]

Good morning,

We have a design where we have an existing orchestration framework on-premise, and starting to look at migrating our workloads to Fabric. Part of our roadmap is to still keep orchestration in the on-premise system until our POC has been proven.

For our requirement now, we need to execute Stored Procedures on the Fabric Datawarehouse.

We are using a Service Pricniple to connect to the Fabric Datawarehouse and execute the Stored Procedure.

All is working as expected, however - we want to trim down the permissions or access the service principle has on the data warehouse, but can't find a way to do this.

I've used the following, but got this error :

 GRANT EXECUTE ON [staging].[myStoredProc] TO [1111-SERVICE-PRINCIPLECLIENTID-1111]

Error:Principal '1111-SERVICE-PRINCIPLECLIENTID-1111' could not be found or this principal type is not supported.

I don't know if there is another way to assign specific permissions to the SERVICE PRINCIPLE.

Hi @arnefromaus 

Thanks for using Microsoft Fabric Community.

Managing permissions for a Service Principal in Microsoft Fabric Data Warehouse can be crucial for security and access control.

For more details please refer to the below documentations:

Link 1 : GRANT (Transact-SQL) - SQL Server | Microsoft Learn

Link 2 : Grant Permissions on a Stored Procedure

I hope this information helps. Please do let us know if you have any further queries.

Thank you.

Thanks for the feedback. 

I am quite confident I have my GRANT statement correct, but have trouble getting the reference to the Entra ID Service Principle correct.   

What "USER_NAME()" do I user to refer to the service principle ?  

Currently I use the "Service Principle Client ID" as copied out of Entra ID as the User_NAME () (also got this when connecting to the DW using SSMS and using USER_NAME())

Currently getting the error message below : 

Principal 'a873f4e8-****-4fb7-a2a5-73256c0cf2d8@37c9a82a-****-4420-****-****cf33c594' could not be resolved. Error message: 'Server identity is not configured. Please follow the steps in "Assign an Azure AD identity to your server and add Directory Reader permission to your identity" (https://aka.ms/sqlaadsetup)
