SharePoint 2013 修改AD密码及一系列问题的解决方法

SharePoint 2013 修改AD密码的完全方案

 首先分析步骤如下三步；

修改密码显示位置。
修改密码的界面
修改密码代码。
修改AD的代码

如果出现如下问题，可能是你的域写错了，这里呀完整的域名称,例如dct.com



如果出现如下问题，是AD控制提示的约束错误。
1，可能是密码约束策略问题，例如强度不够。
2，可能是你的AD策略问题，有的AD限制，一个用户一天只能修改一下密码。
3，错误名称“ 出现一个约束冲突。(异常来自HRESULT:0x8007202F)”
修改3方法，http://forums.manageengine.com/topic/error-8007202f 下图是为了避免域名而引起的错误，自动填充了，域名。



ok 那我开始介绍代码，分为4部分介绍，

[align=left]首先介绍 单击系统帐号下，出现的修改用户密码[/align]



[align=left]再介绍webpart 出现的，界面图2[/align]

[align=left]HTML代码[/align]

<asp:Content ID="Main" ContentPlaceHolderID="PlaceHolderMain" runat="server">

<div>
<h3>
<span>修改密码</span>
</h3>
<table width="400px">
<tr>
<td>
域名全称:(已填充)
</td>
<td>
</td>
<td>
<asp:TextBox ID="txtdomain" runat="server"  >proj.cgdc.com.cn</asp:TextBox>
</td>
</tr>
<tr>
<td>
旧密码 :
</td>
<td>
</td>
<td>
<asp:TextBox ID="txtOld" runat="server" TextMode="Password"></asp:TextBox>
</td>
</tr>
<tr>
<td>

<td>
<asp:TextBox ID="txtPass1" runat="server" TextMode="Password"></asp:TextBox>

</td>
<td>
</td>
<td>
<asp:TextBox ID="txtPass2" runat="server" TextMode="Password"></asp:TextBox>
