问题 I have an ASP.NET application which uses claims bases authentication against ADFS. I also map it to a WindowsClaimsIdentity by using the Claims to Windows Identity Service. That works fine. But now I need to impersonate the current request/thread so I can access a service which is not claims aware. How should I do that?

问题 I have a list in SharePoint 2010. If I add items to the list programmatically (via a custom webpart), I can later read those items and show them in other web parts. However, if I attempt to read a list item added through the web interface, I get the following error in my webpart: Item does not exist. The page you selected contains an item that does not exist.

问题 Can anyone please explain the function of the lines below: WindowsIdentity wId = (WindowsIdentity)HttpContext.Current.User.Identity; WindowsImpersonationContext wIdCon = wId.Impersonate(); That is used on a POST method with IIS basic authentication and works fine.
