Asp.net读取AD域信息的方法（一）
1、首先新建一個頁面（Login.aspx）：
前臺代碼（Login.aspx）：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Login.aspx.cs" Inherits="Login" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
??? <title>無標題頁</title>
</head>
<body>
??? <form id="Login" method="post" runat="server">
????? <asp:Label ID="Label1" runat="server" >Domain:</asp:Label>
????? <asp:TextBox ID="txtDomain" runat="server" ></asp:TextBox><br>????
????? <asp:Label ID="Label2" runat="server" >Username:</asp:Label>
????? <asp:TextBox ID="txtUsername" runat="server" ></asp:TextBox><br>
????? <asp:Label ID="Label3" runat="server" >Password:</asp:Label>
????? <asp:TextBox ID="txtPassword" runat="server" TextMode=Password></asp:TextBox><br>
????? <asp:Button ID="btnLogin" runat="server" Text="Login" OnClick="Login_Click"></asp:Button><br>
????? <asp:Label ID="errorLabel" runat="server" ForeColor=#ff3300></asp:Label><br>
????? <asp:CheckBox ID="chkPersist" runat="server" Text="Persist Cookie" />
??? </form>
</body>
</html>
后臺代碼（Login.aspx.cs）：
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
public partial class Login : System.Web.UI.Page
{
??? protected void Page_Load(object sender, EventArgs e)
??? {
??? }
??? protected void Login_Click(object sender, EventArgs e)
??? {
??????? string adPath = "LDAP://" + txtDomain.Text;
??????? LdapAuthentication adAuth = new LdapAuthentication(adPath);
??????? try
??????? {
??????????? if (true == adAuth.IsAuthenticated(txtDomain.Text, txtUsername.Text, txtPassword.Text))
??????????? {
??????????????? string groups = adAuth.GetGroupByUser();
????????????????
????????????????//Create the ticket, and add the groups.
??????????????? bool isCookiePersistent = chkPersist.Checked;
??????????????? FormsAuthenticationTicket authTicket = new FormsAuthenticationTicket(1,
????????????????????????? txtUsername.Text, DateTime.Now, DateTime.Now.AddMinutes(60), isCookiePersistent, groups);
????????????????//Encrypt the ticket.
??????????????? string encryptedTicket = FormsAuthentication.Encrypt(authTicket);
??????????????? //Create a cookie, and then add the encrypted ticket to the cookie as data.
??????????????? HttpCookie authCookie = new HttpCookie(FormsAuthentication.FormsCookieName, encryptedTicket);
??????????????? if (true == isCookiePersistent)
??????????????????? authCookie.Expires = authTicket.Expiration;
????????????????//Add the cookie to the outgoing cookies collection.
??????????????? Response.Cookies.Add(authCookie);
????????????????//You can redirect now.
??????????????? Response.Redirect(FormsAuthentication.GetRedirectUrl(txtUsername.Text, false));
??????????? }
??????????? else
??????????? {
??????????????? errorLabel.Text = "Authentication did not succeed. Check user name and password.";
??????????? }
??????? }
??????? catch (Exception ex)
??????? {
??????????? errorLabel.Text = "Error authenticating. " + ex.Message;
??????? }
??? }
}
2、在Global.asax里寫：
?void Application_AuthenticateRequest(object sender, EventArgs e)
??? {
??????? string cookieName = FormsAuthentication.FormsCookieName;
??????? HttpCookie authCookie = Context.Request.Cookies[cookieName];
??????? if (null == authCookie)
??????? {
????????????//There is no authentication cookie.
??????????? return;
??????? }
??????? FormsAuthenticationTicket authTicket = null;
??????? try
??????? {
??????????? authTicket = FormsAuthentication.Decrypt(authCookie.Value);
??????? }
??????? catch (Exception ex)
??????? {
????????????//Write the exception to the Event Log.
??????????? return;
??????? }
??????? if (null == authTicket)
??????? {
????????????//Cookie failed to decrypt.
??????????? return;
??????? }
????????//When the ticket was created, the UserData property was assigned a
??????? //pipe-delimited string of group names.
??????? string[] groups = authTicket.UserData.Split(new char[] { '|' });
????????//Create an Identity.
??????? System.Security.Principal.GenericIdentity id = new System.Security.Principal.GenericIdentity(authTicket.Name, "LdapAuthentication");
????????//This principal flows throughout the request.
??????? System.Security.Principal.GenericPrincipal principal = new System.Security.Principal.GenericPrincipal(id, groups);
??????? Context.User = principal;
??? }
3、在Web.Config里加上：
<authentication mode="Forms">
???<forms loginUrl="Login.aspx" name="adAuthCookie" timeout="10" path="/">
???</forms>
??</authentication>
??<authorization>
???<deny users="?"/>
???<allow users="*"/>
??</authorization>
<identity impersonate="true"/>
?
4、再新建一個頁面（WebForm1.aspx）：
前臺代碼（WebForm1.aspx）：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="WebForm1.aspx.cs" Inherits="WebForm1" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
??? <title>無標題頁</title>
</head>
<body>
??? <form id="Form1" method="post" runat="server">
????? <asp:Label ID="lblName" runat="server" /><br/>
????? <asp:Label ID="lblAuthType" runat="server" />
??? </form>
</body>
</html>
后臺代碼（WebForm1.aspx.cs）：
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
public partial class WebForm1 : System.Web.UI.Page
{
??? protected void Page_Load(object sender, EventArgs e)
??? {
??????? lblName.Text = "Hello " + Context.User.Identity.Name + ".";
??????? lblAuthType.Text = "You were authenticated using " + Context.User.Identity.AuthenticationType + ".";
??? }
}
5、再新建一個類（對域的操作主要都要這個類里）：
LdapAuthentication.cs：
using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.DirectoryServices;
using System.Text;
/// <summary>

{
??? public LdapAuthentication()

??? /// <summary>

??? public bool IsAuthenticated(string domain, string username, string pwd)
??? {
??????? string domainAndUsername = domain + @"\" + username;
??????? DirectoryEntry entry = new DirectoryEntry(_path, domainAndUsername, pwd);
??????? try
??????? {
??????????? //Bind to the native AdsObject to force authentication.
??????????? object obj = entry.NativeObject;
??????????? DirectorySearcher search = new DirectorySearcher(entry);
??????????? search.Filter = "(SAMAccountName=" + username + ")";
??????????? search.PropertiesToLoad.Add("cn");
??????????? SearchResult result = search.FindOne();
??????????? if (null == result)
??????????? {
??????????????? return false;
??????????? }
??????????? //Update the new path to the user in the directory.
??????????? _path = result.Path;
??????????? _filterAttribute = (string)result.Properties["cn"][0];
??????? }
??????? catch (Exception ex)
??????? {
??????????? throw new Exception("Error authenticating user. " + ex.Message);
??????? }
??????? return true;
??? }
??? /// <summary>

??? public string GetGroupByUser()
??? {
??????? DirectorySearcher search = new DirectorySearcher(_path);
??????? search.Filter = "(cn=" + _filterAttribute + ")";
??????? search.PropertiesToLoad.Add("memberOf");
??????? StringBuilder groupNames = new StringBuilder();
??????? try
??????? {
??????????? SearchResult result = search.FindOne();
??????????? int propertyCount = result.Properties["memberOf"].Count;
??????????? string dn;
??????????? int equalsIndex, commaIndex;
??????????? for (int propertyCounter = 0; propertyCounter < propertyCount; propertyCounter++)
??????????? {
??????????????? dn = (string)result.Properties["memberOf"][propertyCounter];
??????????????? equalsIndex = dn.IndexOf("=", 1);
??????????????? commaIndex = dn.IndexOf(",", 1);
??????????????? if (-1 == equalsIndex)
??????????????? {
??????????????????? return null;
??????????????? }
??????????????? groupNames.Append(dn.Substring((equalsIndex + 1), (commaIndex - equalsIndex) - 1));
??????????? }
??????? }
??????? catch (Exception ex)
??????? {
??????????? throw new Exception("Error obtaining group names. " + ex.Message);
??????? }
??????? return groupNames.ToString();
??? }
??? /// <summary>

下面列舉一些域中存在的屬性：

?備注：
????????????????? 1. ??在ASP.NET中專用屬性：???
? ? ? ? ? ?? 獲取服務器電腦名：Page.Server.ManchineName ??
? ? ? ? ? ?? 獲取用戶信息：Page.User ??
? ? ? ? ? ?? 獲取客戶端電腦名：Page.Request.UserHostName ??

? ? ? ? ? ??2. ??在網(wǎng)絡編程中的通用方法：???
? ? ? ? ? ?? 獲取當前電腦名：static ? System.Net.Dns.GetHostName() ??
? ? ? ? ? ?? 根據(jù)電腦名取出全部IP地址：static ? System.Net.Dns.Resolve(電腦名).AddressList ??
