增加SharePoint2010修改域密码功能

前提

SharePoint2010的用户基于AD的，因此修改密码是修改了AD的密码，当然也可以修改本机密码（非域的密码）。这里我们讨论修改域密码。我们修改需要用到sharepoint的弹出对话框的模式，以下为几个对话框函数：

Ø SP.UI.ModalDialog.showModalDialog：弹出对话框

Ø SP.UI.Status.addStstus：自定义状态栏信息

Ø SP.UI.Notify.addNotification：自定义消息通知

配置开发

1. 使用sharepoint designer2010打开对应站点http://moss:8002 ,找到v4.master如下图：

2. 打开编辑v4.master，如下图：

添加JS代码：


采用自定义通知栏模式
<script language="javascript" type="text/javascript">
    function portal_openModalDialog() 
    {
        var options = SP.UI.$create_DialogOptions();
        options.width = 500;
        options.height = 250;
        options.url = "/_layouts/TCL.EG.ModifyPasswd/ModifyPasswd.aspx";
        options.dialogReturnValueCallback = Function.createDelegate(null, portal_modalDialogClosedCallback);
        SP.UI.ModalDialog.showModalDialog(options);
    }
    //关闭函数
    function portal_modalDialogClosedCallback(result, value) 
    {
        if (value == "1") 
        {
            //自定义通知栏
SP.UI.Notify.addNotification("恭喜！修改成功！");
        }
        else if (value == "0") 
        {
			//自定义通知栏
            SP.UI.Notify.addNotification("修改失败,请联系管理员！");
        }
       
    }
    //关闭函数
    function closeDialog() 
    {
        SP.UI.ModalDialog.commonModalDialogClose(SP.UI.DialogResult.cancel, 3);
    }
</script>
	
采用自定义状态栏模式
<script language="javascript" type="text/javascript">
    function portal_openModalDialog() 
    {
        var options = SP.UI.$create_DialogOptions();
        options.width = 500;
        options.height = 250;
        options.url = "/_layouts/TCL.EG.ModifyPasswd/ModifyPasswd.aspx";
        options.dialogReturnValueCallback = Function.createDelegate(null, portal_modalDialogClosedCallback);
        SP.UI.ModalDialog.showModalDialog(options);
    }
    //关闭函数
    function portal_modalDialogClosedCallback(result, value) 
    {
        if (value == "1") 
        {
            //自定义状态栏
		this.statusId  = SP.UI.Status.addStatus ("恭喜！修改成功！",“修改密码成功,请重新登录！”,true);
        }
        else if (value == "0") 
        {
			//自定义通知栏
		this.statusId =SP.UI.Status.addStatus ("修改失败！",“修改失败,请联系管理员！”,true);
        }
       		SP.UI.Status.setStatusPriColor(this.statusId, "Green");
		setTimeout(RemoveStatus, 6000);
}
function RemoveStatus() {
SP.UI.Status.removeStatus(this.statusId); 
 
}
    //关闭函数
    function closeDialog() 
    {
        SP.UI.ModalDialog.commonModalDialogClose(SP.UI.DialogResult.cancel, 3);
    }
</script>

加入母版页面中，签入即可，如下图：

3. 使用VS2010开发添加sharepoint空白项目，如下图：

4. 添加空元素，如下图：

<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
  <CustomAction 
      Id="{BC477D9E-365A-47BD-AB2B-BE06FA44628D}"
      Title="修改密码"
      Description="此处修改的是域里面的密码"
      Sequence="1000"
      Location="Microsoft.SharePoint.StandardMenu"
      GroupId="PersonalActions"
      ImageUrl="~sitecollection/_layouts/images/menulistsettings.gif">
    <UrlAction Url="javascript:portal_openModalDialog();"/>
  </CustomAction>
</Elements>

5. 添加修改密码的页面，页面代码部分如下：

            </td>
        </tr>
    </table>
   
</asp:Content>
<asp:Content ID="PageTitle" ContentPlaceHolderID="PlaceHolderPageTitle" runat="server">

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Security.Principal;
namespace TCL.EG.ModifyPasswd
{
    public class Impersonator
    {
        private WindowsImpersonationContext ctx = null;
        public bool IsImpersonated { get; set; }
        public void BeginImpersonation()
        {
            try
            {
                if (!WindowsIdentity.GetCurrent().IsSystem)
                {
                    ctx = WindowsIdentity.Impersonate(WindowsIdentity.GetCurrent().Token);
                    IsImpersonated = true;
                }
            }
            catch
            {
                IsImpersonated = false;
            }
        }
        public void StopImpersonation()
        {
            if (ctx != null)
            {
                ctx.Undo();
            }
        }
    }
}

8. 部署后，看下效果图：

注意事项：

1、密码复杂度策略，最好合符要求，否则会提示：密码不合符复杂度策略。要不，干脆不禁用此策略，在代码中用自己定义策略，用正则表达式，如下图：

2、为了能每天多次修改密码，此时应当禁用如下策略，如下图：
