Reporting Services 2012 Integrated Mode with SharePoint 2013

Hi,

I'm facing a strange error coming from my SharePoint 2013,

• An error has occurred during report processing. (rsProcessingAborted)
  • Cannot impersonate user for data source 'ProductSales'. (rsErrorImpersonatingUser)
    • Can not convert claims identity to windows token. This may be due to user not logging in using windows credentials. (rsClaimsToWindowsTokenLoginTypeError)

All is installed on the same machine for developpement team.

Windows2008R2SP1 Full Updated

SQL2012 with SP1

SharePoint 2013 (with trial Licence - users should update it once they got the virtual machine)

I've downloaded Report Builder 3.0 Sample to add them to the SP Library

And the previous error is showing.

I've double check the installation, that should be ok.

I've also check:

IIS Advanced Settings

There is no special configuration on SQL Reporting Services (i mean all is by default)

If anyone could help :-)

Many thanks,

Michael
