c# - 从 C# 访问 AD 时出现 "A referral was returned from the server"异常

Question

DirectoryEntry oDE = new DirectoryEntry("LDAP://DC=Test1,DC=Test2,DC=gov,DC=lk");

using (DirectorySearcher ds = new DirectorySearcher(oDE))
{
    ds.PropertiesToLoad.Add("name");
    ds.PropertiesToLoad.Add("userPrincipalName");

    ds.Filter = "(&(objectClass=user))";

    SearchResultCollection results = ds.FindAll();

    foreach (SearchResult result in results)
    {
        Console.WriteLine("{0} - {1}",
            result.Properties["name"][0].ToString(),
            result.Properties["userPrincipalName"][0].ToString());
    }
}

在 SearchResultCollection results = ds.FindAll(); 行我得到一个异常:

A referral was returned from the server

为什么会出现该异常，这意味着什么？

Answer 1

可能您提供的路径不正确。检查一下。

我会推荐这篇文章 Howto: (Almost) Everything In Active Directory via C#这在过去确实帮助了我处理 AD。
