Active Directory：无法使用 DirectorySearcher 联系服务器

Question

我一直收到错误 无法联系服务器。 当我尝试运行我的代码时：

找了几个小时，还是联系不上服务器

DirectorySearcher directorySearcher = new DirectorySearcher();
string path = directorySearcher.SearchRoot.Path;
DirectoryEntry directoryEntry = new DirectoryEntry(path);

PrincipalContext pricipalContext = new PrincipalContext(ContextType.Domain, "LDAP://domain.dk/DC=domain,DC=dk");
//GroupPrincipal group = GroupPrincipal.FindByIdentity(pricipalContext, "(CN=" + department + ")");
GroupPrincipal group = GroupPrincipal.FindByIdentity(pricipalContext, "(CN=" + department + ")");


if (group != null)
{
    foreach (Principal principal in group.Members)
    {
        UserPrincipal tu = principal as UserPrincipal;

        DirectoryEntry de = tu.GetUnderlyingObject() as DirectoryEntry;
        var store = de.InvokeGet("physicalDeliveryOfficeName").ToString();
        var storeNumber = de.InvokeGet("description").ToString();

        employees.Add(new AdEmployees() { name = principal.Name, phone = tu.VoiceTelephoneNumber, email = tu.EmailAddress, store = store.ToString(), storeNumber = storeNumber.ToString(), link = GenerateLink(principal.Name) });
    }
}

注意：我把AD所在的域改成域了。

Answer 1

这里的关键语句似乎是"I changed my domain where the AD is located to domain."

确保应用程序服务器指向正确的 DNS 服务器。
确保客户端指向正确的 DNS 服务器。
此连接字符串看起来有误：PrincipalContext pricipalContext = new PrincipalContext(ContextType.Domain, "LDAP://domain.dk/DC=domain,DC=dk");
#3 中的连接字符串可能像这样工作得更好：

PrincipalContext pricipalContext = new PrincipalContext(ContextType.Domain, "DOMAIN", "DC=domain,DC=dk");
