sharepoint 2013 开启切换帐户效能

sharepoint2013以前版本，有更换账户功能，到了sharepoint2013，则隐藏了这个功能，有时候我们在测试机上调试东西，需要切换账户，就变得非常麻烦，但问题总是有解决的方法，下面将介绍在2013上如何恢复切帐户功能

1. 首先找到文件路径：C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\TEMPLATE\CONTROLTEMPLATES
2. 用记事本编辑器打开Welcome.ascx 文件，其中有颜色部分是需要加入其中的代码段。
