Connect Onedrive/Sharepoint file as datasource in Report Server

Hi guys,

I'm using the web connector as described in the documentation (Link) to successfully connect to the file in Power BI Desktop and Power BI Service. Only the Report Server is causing trouble.

I think It may be related to the fact, that the Report Server does not support OAuth2 according to this article (Link). That's why I can't choose the "Organizational" authentication method like I would in Power BI Desktop or Service.

Full Disclosure: The request might be blocked by the firewall but the question still stands.

Is it possible to connect to Teams/Sharepoint without using OAuth2?

Best regards

Lucas
