以编程方式确定当前域控制器

发布于 2024-09-28 18:52:15 字数 136 浏览 15 评论 0原文

我需要查询当前的域控制器,可能主要是为了更改用户密码。

(P)DC 名称应该是完全限定的,即 DC=pdc,DC=example,DC=com (如何正确命名此类表示法?)

如何使用 C# 来完成?

I need to query current domain controller, probably primary to change user password.

(P)DC name should be fully qualified, i.e. DC=pdc,DC=example,DC=com (how to properly name such notation?)

How can it be done using C#?

DomainController 存在于您的计算机不属于的域中时,要检索信息,您还需要更多东西。

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

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

To retrieve the information when the DomainController exists in a Domain in which your machine doesn't belong, you need something more.

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

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

我们在内部应用程序中使用类似的东西。

应该返回类似 DC=d,DC=r,DC=ABC,DC=com

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;
}

We are using something like this for our internal applications.

Should return something like DC=d,DC=r,DC=ABC,DC=com

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;
}

(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)));
}

(requires 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" }

    // or just in one string

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

如果您希望与 Active Directory 进行交互,则不必知道 FSMO 角色占大多数。如果您想从程序中更改 AD 拓扑(我不会),请查看 DomainController 类。

如果要更改用户密码,可以对用户对象调用这些操作,Active Directory 将确保正确复制更改。

复制自 http://www.rootsilver.com/2007 /08/如何更改用户密码

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");
}

If you are looking to interact the Active Directory, you shouldn't have to know where the FSMO roles are for the most part. If you want to change the AD topology from your program (I wouldn't), look at the DomainController class.

If you want to change a user password, you can invoke those actions on the User object, and Active Directory will make sure that the changes are properly replicated.

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");
}
