sharepoint默认是没有修改AD密码 和切换 用户的功能，这里我用future的方式来实现。

　　部署wsp前：

　　部署后：

　　点击以其他用户身份登录

　　点击修改用户密码：

　　这里的扩展才菜单我们用CustomAction来实现，我们需要添加空项目来部署它

　　以其他用户身份登录得xml如下：

　　修改用户密码的xml如下：

　　这里我们需要新建一个应用程序页面，首先需要添加路径映射：

　　添加应用程序页面的代码如下：

　　<%@AssemblyName="$SharePoint.Project.AssemblyFullName___FCKpd___0quot;%><%@ImportNamespace="Microsoft.SharePoint.ApplicationPages"%><%@RegisterTagprefix="SharePoint"Namespace="Microsoft.SharePoint.WebControls"Assembly="Microsoft.SharePoint,Version=15.0.0.0,Culture=neutral,PublicKeyToken=71e9bce111e9429c"%><%@RegisterTagprefix="Utilities"Namespace="Microsoft.SharePoint.Utilities"Assembly="Microsoft.SharePoint,Version=15.0.0.0,Culture=neutral,PublicKeyToken=71e9bce111e9429c"%><%@RegisterTagprefix="asp"Namespace="System.Web.UI"Assembly="System.Web.Extensions,Version=4.0.0.0,Culture=neutral,PublicKeyToken=31bf3856ad364e35"%><%@ImportNamespace="Microsoft.SharePoint"%><%@AssemblyName="Microsoft.Web.CommandUI,Version=15.0.0.0,Culture=neutral,PublicKeyToken=71e9bce111e9429c"%><%@PageLanguage="C#"AutoEventWireup="true"CodeBehind="ChangePassword.aspx.cs"Inherits="SharePointProjectDemo.Layouts.ChangePassword.ChangePassword"DynamicMasterPageFile="~masterurl/default.master"%>
