HOWTO - 设置委派的 Active Directory 权限

Question

我创建了 ac# webservice，它允许我们的前端支持团队使用 system.directoryservices 查看和更新​​一些选定的 Active Directory 值。

我要更新的字段是 [职位] 职称、部门、电话和员工 ID。

我可以使用具有“代表权限”的服务帐户来更新[职位]职称、部门、电话等。但是当我尝试更新员工 ID 时，我收到一条“未经授权”的错误消息。

如果我使用域管理员帐户，那么相同的代码可以正常工作。

我不想为此网络服务使用域管理员帐户，那么我需要什么权限？

Answer 1

答案

ADS_SCHEMA_ID_GUID_USER GUID 允许您更新基本用户类详细信息，包括员工 ID

基于 MSDN 文章

用于向服务帐户用户授予所选委派权限的 vbscript：

代码示例（至少是移动部分）

string distinguishedname = "CN=Wicks\, Guy,OU=Users,DC=ad,DC=com"
using (DirectoryEntry myDirectoryEntry = new DirectoryEntry(string.Format("LDAP://{0}", distinguishedname), null, null, AuthenticationTypes.Secure))
{
    try
    {
        myDirectoryEntry.Username   = "serviceaccount";
        myDirectoryEntry.Password   = "pa55word";

        myDirectoryEntry.Properties["employeeid"][0]    = employeeID;
        myDirectoryEntry.CommitChanges();
        setresult.result        = myDirectoryEntry.Properties["employeeid"][0].ToString();
    }
    catch   ( Exception ex )
    {
        setresult.result        = ex.Message;
    }
} // end using

你们服务的用户是否有权通过AD用户和计算机修改这些字段？
如果是的话，那么也许您可以使用模拟，并使您的服务主机“受信任委托”（在 AD 属性中）对我来说总是工作得很好。
