从不同域 C# 将用户添加到 AD 通用组

Question

我们在同一个林中有许多域（即 sw.main.company.com、nw.main.company.com、main.company.com），我控制 sw.main.company.com 中的一个 OU我在其中设置了一个通用 Active Directory 组。

在默认 AD 端口上使用 System.DirectoryServices.AccountManagement .NET 4.5 等将“sw”域用户添加到组中没有困难（c#），但是在添加来自其他域的用户时（nw , mw 等），我在设置新的 PrincipalContext(ContextType.Domain "sw .main.company.com:3268", "DC=main,DC=company,DC=com")。

所有域控制器也是全局目录服务器，调用端口 3268 允许来自其他域的用户正确解析，但我无法使用 GlobalPrincipal.Save() 命令提交添加而不抛出错误。

我已经包含了下面的相关代码以及详细的错误堆栈。我需要这方面的帮助。

public void SyncADUsers()
{
    AddUserToGroup("MW\\abc123user", "Universal_Group_1");
}

public void AddUserToGroup(string userId, string groupName)
{
    try
    {
        using (PrincipalContext pc = new PrincipalContext(ContextType.Domain, "sw.main.company.com:3268", "DC=main,DC=company,DC=com"))
        {
            GroupPrincipal group = GroupPrincipal.FindByIdentity(pc, groupName);
            group.Members.Add(pc, IdentityType.SamAccountName, userId);
            group.Save();
        }
    }
    catch (System.DirectoryServices.DirectoryServicesCOMException E)
    {
        //doSomething with E.Message.ToString(); 
    }
}

参考 BaldPate 的回复，如果 Global Catalog 是只读的，我们需要使用 3268 端口读取并解析不同域中的用户，然后将使用 389 端口的用户全部保存在同一上下文中。这可以通过以下代码完成（注意分别调用 3268 和默认 389 端口），感谢 BaldPate 明确说明：

Answer 2

全局目录是只读的。

请连接到 LDAP 端口（默认 389）以更新组。
