c# - 将来自不同域的用户添加到 AD 通用组 C#

Question

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

我在默认 AD 端口上使用 System.DirectoryServices.AccountManagement .NET 4.5 等实用地 (c#) 将“sw”域用户添加到组中没有任何困难，但是当涉及到从其他域添加用户时 (nw , mw, 等)，当设置新的 PrincipalContext(ContextType.Domain "sw .main.company.com:3268", "DC=main,DC=company,DC=com").

所有域 Controller 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，但我无法在不抛出错误的情况下使用 GlobalPrincipal.Save() 命令提交添加。

我在下面包含了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(); 
    }
}

引用BaldPate的回应，如果全局目录是只读的，我们需要使用3268端口读取和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(注意对 3268 和默认 389 端口的单独调用)并感谢 BaldPate 使这一点变得清晰:
