public interface ITokenDataExtension


Sets the SharePoint user token. This method is used by the report server to send the SharePoint user token to the data processing extension.

The report server sends the SharePoint user's security token to a data processing extension under the following circumstances:

  • The report server is in SharePoint integrated mode.

  • The data processing extension implements the ITokenDataExtension interface.

It is recommended that you configure the unattended execution account on the report server. If the report server cannot obtain a user token, it creates a SharePoint token of its unattended execution account. For more information, see Configure the Unattended Execution Account (SSRS Configuration Manager).

The report server will allow the data source to use stored, non-windows credentials. A best practice is to avoid implementing revert-to-self logic because the result may be the Report Server service identity is used when connecting to data sources.
