I have Power View installed and configured (SQL 2012 SP1 CU4), and creating reports through the browser is working absolutely fine.
However, if I export to PowerPoint and then try to "Interact" with the embedded reports I get an error message:
Report Server has encountered a SharePoint error. ---> Microsoft.ReportingServices.Diagnostics.Utilities.SharePointException: Report Server has encountered a SharePoint error. ---> Microsoft.SharePoint.SPException:The user does not exist or is not unique. ---> System.Exception: For more information about this error navigate to the report server on the local server machine, or enable remote errors
