process model in Azure SSAS, connect to SQL Data Warehouse, data source, service principal RRS feed

  • Question

  • Have someone ever managed to authenticate as a service principal in the data source of the model to the sql database?

    I have model in Azure SSAS. The data source is in SQL Data Warehouse. I process the model with powershell. Currently I have set up the connection in the model with a SQL login and password, but I want authenticate with my service princial in order to avoid a sql login and password.

    I only get messages such as "'Windows authentication has been disabled in the current context.. The exception was raised by the IDbCommand interface."

  • If you have tried to create a project in SSAS, you will see that you need to create a data source. This data source requires a way to authenticate yourself towards the data source.

    The power shell aspect of this is in the process of connecting from Azure Automation to the SSAS instance. This works fine.

    What we need is a way the impersonate the user, the service principal, towards the database in the data souce of the model.

    The problem seems to be limitations in the data source of the model. It may seem as there is no such way to accomplish this in Azure SSAS, but only in a onprem scenario.

    The problem is not the power shell script.

  • Not really.

    Guess using key vault and powershell is a satisfying workaround.
