业务介绍
因为一个业务需要在域用户上增加一个属性，来存储一个特定的路径标识。在网上搜了下自定义属性，没找到太具体的介绍，于是看了下官网文档。本次测试增加的属性名为userPdictionary
系统环境
- Windows Server 2016 Standard
- AD
- DNS
操作步骤
AD搭建步骤略
开启MMC中的Active Directory架构
在cmd中执行regsvr32 schmmgmt.dll
regsvr32 schmmgmt.dll
在mmc中添加Active Directory架构
在运行中输入mmc，启动控制台，选择“文件-添加/删除管理单元”,
选择“Active Directory架构--添加--确定”，
此时左侧可以看到当前AD中的类及属性
添加自定义属性
在左侧属性上点击右键,选择“新建--属性”，然后选择继续即可
此时可以看到创建新属性的界面，主要参数有：
- 公用名
- LDAP显示名
- 唯一的X500对象ID
- 描述
这里主要需要说明的是“唯一的X500对象ID”
获取对象标识符
根据官网说明
(Oid) 对象标识符是由各种颁发机构颁发的唯一数字值，用于唯一标识分布式应用程序的数据元素、语法和其他部分。 在 OSI 应用程序、X 500 目录、SNMP 和其他应用程序中可以找到 Oid，其中的唯一性非常重要。 Oid 基于树结构，在该结构中，高级颁发机构（如 ISO）将树的分支分配给 subauthority，后者又可以分配子。
LDAP 协议 (RFC 2251) 需要目录服务以使用 Oid 识别对象类、属性和语法。 这是 LDAP X. 500 旧版本的一部分。
Active Directory 域服务中的 Oid 包括 ISO 为 X. 500 类和属性颁发的部分，以及由 Microsoft 和其他颁发机构颁发的部分。 OID 表示法是一串数字，例如 "1.2.840.113556.1.5.9"，下表对此进行了说明。
| 值 | 含义 | 描述 |
|---|---|---|
| 1 | ISO | 标识根证书颁发机构。 |
| 2 | ANSI | ISO 指定的组指定。 |
| 840 | USA | 组分配的国家/地区指定。 |
| 113556 | Microsoft | 国家/地区分配的组织称号。 |
| 1 | Active Directory | 由组织分配。 |
| 5 | 类 | 由组织分配。 |
| 9 | 用户 类 | 由组织分配。 |
| 上面中的“唯一的X500对象ID”在官网文档中叫做对象标识符，在扩展本地的域架构时，需要获取本地的对象标识符。这里按照文旦介绍，使用“从 Microsoft 获取对象标识符”。 |
若要成功扩展 Active Directory 架构，可以从如下所示的脚本中获取根 OID。 从脚本生成的 Oid 是唯一的;它们是从唯一的 GUID 映射的。 请仔细阅读最佳做法，因为处理不当的 Oid 会导致数据丢失。
获取根OID的脚本如下:

通过cmd中运行该脚本,获取当前AD的OID,本次测试中生成的oidinfo.txt内容如下：
Your root OID is:
1.2.840.113556.1.8000.2554.55786.31829.55335.19299.48276.12206014.6177421
This prefix should be used to name your schema attributes and classes. For example: if your prefix is "Microsoft", you should name schema elements like "microsoft-Employee-ShoeSize". For more information on the prefix, view the Schema Naming Rules in the server Application Specification (http://www.microsoft.com/windowsserver2003/partners/isvs/appspec.mspx).
You can create subsequent OIDs for new schema classes and attributes by appending a .X to the OID where X may be any number that you choose. A common schema extension scheme generally uses the following structure:
If your assigned OID was: 1.2.840.113556.1.8000.2554.999999
then classes could be under: 1.2.840.113556.1.8000.2554.999999.1
which makes the first class OID: 1.2.840.113556.1.8000.2554.999999.1.1
the second class OID: 1.2.840.113556.1.8000.2554.999999.1.2 etc...
Using this example attributes could be under: 1.2.840.113556.1.8000.2554.999999.2
which makes the first attribute OID: 1.2.840.113556.1.8000.2554.999999.2.1
the second attribute OID: 1.2.840.113556.1.8000.2554.999999.2.2 etc...

获取基 OID 后
如果有一个基本 OID，请在决定如何将 Oid 划分为多个类别时小心，因为这些 Oid 包含在前缀表中，并且是 DC 复制数据的一部分。 建议不要创建两个以上的 OID 类别。
可以通过将数字追加到 oid 的形式，为新架构类和属性创建后续 Oid。X，其中 X 可以是你选择的任何数字。 常见的架构扩展通常使用以下结构：
如果分配的基本 OID 为1.2.840.113556.1.8000.999999，则可以按如下所示创建类别。
| OID 基值 | 描述 |
|---|---|
| 1.2.840.113556.1.8000.999999.1 | 应用程序类 ,第一个类将具有 OID 1.2.840.113556.1.8000.999999.1.1，第二个类将具有 OID 1.2.840.113556.1.8000.999999.1.2，依此类推。 |
| 1.2.840.113556.1.8000.999999.2 | 应用程序属性 , 第一个属性的 OID 为1.2.840.113556.1.8000.999999.2.1，第二个属性的 OID 为1.2.840.113556.1.8000.999999.2.2，依此类推。 |
| 按照文档中要求，测试中设置id为 |
1.2.840.113556.1.8000.2554.55786.31829.55335.19299.48276.12206014.6177421.2.1
最终配置如下:
将属性关联到类
在类项目下选择user，右键--属性，如图
选择属性标签,在可选项目中，将自定义的属性添加进来，之后点击确定
安装必须执行的操作
扩展该架构的应用程序必须按以下过程所述应用更新。在扩展架构时应用更新
- 添加新属性。
- 添加新类。
- 将新属性添加到类。
- 触发缓存重新加载。
由于此时架构缓存中不存在新的属性名称，在步骤3中引用的新属性必须由其 OID 引用。
如果不立即使用扩展，则不需要步骤 4;扩展将在大约5分钟的时间内出现在架构缓存中，具体取决于系统负载。 有关架构缓存和如何触发缓存重新加载的详细信息，请参阅更新架构缓存。
编辑属性内容
在ad的用户和计算机中，编辑用户的属性即可。
