SHAREPOINT 2013 – 以其它身份登陆
SharePoint 2013 for some reason does not include the ability to log in as another user.
To install this fix simply drag the link below to your favorites bar to create a bookmarklet that will work on any SharePoint 2013 site. Whenever you want to log in as another user simply click your bookmark and you’ll be redirected to this Windows Authentication dialog so that you may log in as you would expect.
