I think that is because your code can impersonate ASP.NET authentication, but sharepoint use IIS authentication ,your code dosen't work. A domain controller is not available to validate the user identity. But, using the control, we can eliminate the necessity of controlling logon through IIS, and enable it through our code. http://stackoverflow.com/questions/8993293/windowsidentity-impersonate-in-asp-net-randomly-invalid-token-for-impersonation Console.WriteLine("After impersonation: " + WindowsIdentity.GetCurrent().Name); } // Releasing the context object stops the impersonation // Check the identity.
