从 Microsoft 获取对象标识符

项目
03/04/2024

要成功扩展 Active Directory 架构，可以从如下所示的脚本中获取根 OID。脚本生成的 OID 是唯一的；它们是从唯一的 GUID 映射而来。请仔细阅读最佳做法，因为 OID 处理不当可能会导致数据丢失。

注意

有关从 Microsoft 获取链接 ID 的说明，请访问链接属性主题。

在获取基本 OID 后

一旦有了基本 OID，在确定如何将 OID 分门别类时要小心谨慎，因为这些 OID 包含在前缀表中，并且是 DC 复制数据的一部分。建议创建的 OID 类别不超过两个。

通过在 OID 中添加数字 OID.X（其中 X 可以是选择的任何数字），可以为新架构类和属性创建后续 OID。通用架构扩展通常采用以下结构：

如果分配的基础 OID 是 1.2.840.113556.1.8000.999999，则可以按照如下所示来创建类别。

OID 基值	说明
1.2.840.113556.1.8000.999999.1	应用程序类第一个类的 OID 是 1.2.840.113556.1.8000.999999.1.1，第二个类的 OID 是 1.2.840.113556.1.8000.999999.1.2，以此类推。
1.2.840.113556.1.8000.999999.2	应用程序属性第一个属性的 OID 是 1.2.840.113556.1.8000.999999.2.1，第二个属性的 OID 是 1.2.840.113556.1.8000.999999.2.2，以此类推。
