(使用LDAP群組cn,ou,dc寫法)

Login.aspx.cs

using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.DirectoryServices;
using System.Linq;
using System.Security.Principal;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;



public partial class Login : System.Web.UI.Page
{
 protected void Page_Load(object sender, EventArgs e)
 {

 }
 public static string ValidateUser(string ComputerName, string UserName, string Password)
 {


 if (ComputerName.IndexOf('.') != -1)
 {
 DirectoryEntry entry = new DirectoryEntry("LDAP://test.com.tw/cn=" + UserName + ",ou=user,ou=test,ou=test,ou=manger,dc=test,dc=com,dc=tw", UserName, Password);
 try
 {
 string objectSid =
 (new SecurityIdentifier((byte[])entry.Properties["objectSid"].Value, 0).Value);

 return objectSid;
 }
 catch
 {
 return null;
 }
 finally
 {
 entry.Dispose();
 }
 }
 else
 {
 DirectoryEntry entry = new DirectoryEntry("WinNT://" + ComputerName, UserName, Password);
 try
 {
 string objectSid =
 (new SecurityIdentifier((byte[])entry.Properties["objectSid"].Value, 0).Value);

 return objectSid;
 }
 catch
 {
 return null;
 }
 finally
 {
 entry.Dispose();
 }
 }
 }

 protected void Login1_Authenticate(object sender, AuthenticateEventArgs e)
 {
 string strComputerName = "test.com.tw";
 string strUserName = ((System.Web.UI.WebControls.Login)sender).UserName;
 string strPassword = ((System.Web.UI.WebControls.Login)sender).Password;

 string strValidateUser = ValidateUser(strComputerName, strUserName, strPassword);

 if (strValidateUser != null)
 {
 e.Authenticated = true;
 }
 else
 {
 e.Authenticated = false;
 }
 }

}

LDAP的寫法若不正確將導致無法登入到AD

试试其它关键字
