Course 10778 Implementing Data Models and Reports with Microsoft SQL Server 2012

Question

Hi,
I recently imported the virtual machines for the above-mentioned course. I am running Windows Server 2012 Standard edition on my pc. When I tried the first lab exercise, I could
not open the report in MS Sharepoint Server. The error was to do with the following: "cannot impersonate user for data source 'AdventureWorksDW' ", and also "cannot convert claims identity to windows token sharepoint". I followed all the
steps in the setup guide.
Please assist me with this regard,
Many thanks.

Hi Zimiso,
Based on the error message, it seems that the issue is caused by the incorrect configuration of Claims to Windows Token Service (C2WTS) that it was not running under a domain account.
The domain account used by the Claims to Windows Token Service needs to be granted the following rights through the Local Security Policy:
Act as part of the operating system
Impersonate a client after authentication
Log on as a service
We can find these settings under Administrative Tools > Local Security Policy > Local Policies > User Rights Assignment. Please note that we should add the service account to the local Administrators Groups ahead.
