Active Directory：无法使用DirectorySearcher

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：

我搜索了几个小时，但我仍然无法联系服务器。

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：我将AD所在的域名更改为域名。

Answer 1

这里的关键声明似乎是＆＃34;我将AD所在的域名更改为域名。＆＃34;

1. 确保应用程序服务器指向正确的DNS服务器。
2. 确保客户端指向正确的DNS服务器。

3. 此连接字符串显示错误：PrincipalContext pricipalContext = new PrincipalContext(ContextType.Domain, "LDAP://domain.dk/DC=domain,DC=dk");

4. ＃3中的连接字符串可能效果更好：

   PrincipalContext pricipalContext = new PrincipalContext（ContextType.Domain，＆＃34; DOMAIN＆＃34;，＆＃34; DC = domain，DC = dk＆＃34;）;
