以编程方式确定当前域控制器

我需要查询当前的域控制器,可能是主要的更改用户密码。

(P)DC名称应该是完全合格的,即DC=pdc,DC=example,DC=com(如何恰当地命名这种表示法?)

如何使用C#完成?

要在您的机器所属的域中存在DomainController时检索信息,您需要更多内容。

  DirectoryContext domainContext =  new DirectoryContext(DirectoryContextType.Domain, "targetDomainName", "validUserInDomain", "validUserPassword");

  var domain = System.DirectoryServices.ActiveDirectory.Domain.GetDomain(domainContext);
  var controller = domain.FindDomainController();

(需要System.DirectoryServices.AccountManagement.dll):

using (var context = new System.DirectoryServices.AccountManagement.PrincipalContext(ContextType.Domain))
{
    string server = context.ConnectedServer; // "pdc.examle.com"
    string[] splitted = server.Split('.'); // { "pdc", "example", "com" }
    IEnumerable<string> formatted = splitted.Select(s => String.Format("DC={0}", s));// { "DC=pdc", "DC=example", "DC=com" }
    string joined = String.Join(",", formatted); // "DC=pdc,DC=example,DC=com"

    // or just in one string

    string pdc = String.Join(",", context.ConnectedServer.Split('.').Select(s => String.Format("DC={0}", s)));
}

我们正在为我们的内部应用程序使用这样的东西。

应返回DC=d,DC=r,DC=ABC,DC=com

之类的内容
public static string RetrieveRootDseDefaultNamingContext()
{
    String RootDsePath = "LDAP://RootDSE";
    const string DefaultNamingContextPropertyName = "defaultNamingContext";

    DirectoryEntry rootDse = new DirectoryEntry(RootDsePath)
    {
        AuthenticationType = AuthenticationTypes.Secure;
    };
    object propertyValue = rootDse.Properties[DefaultNamingContextPropertyName].Value;

    return propertyValue != null ? propertyValue.ToString() : null;
}

如果您希望与Active Directory进行交互,则不必知道FSMO角色的大部分位置。如果要从程序中更改AD拓扑(我不愿意),请查看DomainController类。

如果要更改用户密码,可以在User对象上调用这些操作,Active Directory将确保正确复制更改。

复制
public static void ChangePassword(string userName, string oldPassword, string newPassword)
{
        string path = "LDAP://CN=" + userName + ",CN=Users,DC=demo,DC=domain,DC=com";

        //Instantiate a new DirectoryEntry using an administrator uid/pwd
        //In real life, you'd store the admin uid/pwd  elsewhere
        DirectoryEntry directoryEntry = new DirectoryEntry(path, "administrator", "password");

        try
        {
           directoryEntry.Invoke("ChangePassword", new object[]{oldPassword, newPassword});
        }
        catch (Exception ex)  //TODO: catch a specific exception ! :)
        {
           Console.WriteLine(ex.Message);
        }

        Console.WriteLine("success");
}
