SharePoint 2013设置“以其他用户身份登录”

登录web服务器，打开位于“C:\Program Files\Common Files\microsoft shared\Web Server Extensions\15\TEMPLATE\CONTROLTEMPLATES”目录下的“Welcome.ascx”文件，增加如下代码：

<SharePoint:MenuItemTemplate runat="server" ID="ID_LoginAsDifferentUser"
                Text="<%$Resources:wss,personalactions_loginasdifferentuser%>"
                Description="<%$Resources:wss,personalactions_loginasdifferentuserdescription%>"
                MenuGroupId="100"
                Sequence="100" UseShortId="true" 
                />

整个文件代码如下：
