1.利用DirectoryEntry模拟域帐号登录
前台代码：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!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></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<table>
<tr>
<td>用户名:</td>
<td>
<asp:TextBox ID="txtUserName" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td>密码:</td>
<td>
<asp:TextBox ID="txtPassword" runat="server" TextMode="Password"></asp:TextBox>
</td>
</tr>
<tr>
<td>域:</td>
<td>
<asp:DropDownList ID="ddlDomain" runat="server">
<asp:ListItem Value="TestDomain">TestDomain</asp:ListItem>
</asp:DropDownList>
</td>
</tr>
<tr>
<td align="center" colspan="2">
<asp:Button ID="btnLogin" runat="server" Text="登录" onclick="btnLogin_Click" /></td>
</tr>
</table>
<asp:Label ID="lblMsg" runat="server" Text=""></asp:Label>
</div>
</form>
</body>
</html>
后台代码：
protected void btnLogin_Click(object sender, EventArgs e)
{
try
{
using (DirectoryEntry deUser = new DirectoryEntry(@"LDAP://" + ddlDomain.SelectedValue, txtUserName.Text.Trim(),txtPassword.Text.Trim()))
{
DirectorySearcher src = new DirectorySearcher(deUser);
//src.Filter = ("(objectClass=user)");
src.Filter = "(&(&(objectCategory=person)(objectClass=user))(sAMAccountName="+txtUserName.Text.Trim()+"))";
src.PropertiesToLoad.Add("cn");
src.SearchRoot = deUser;
src.SearchScope = SearchScope.Subtree;
SearchResult result = src.FindOne();
if (result != null)//登录成功
{
DirectoryEntry de = result.GetDirectoryEntry();
foreach (var p in de.Properties.PropertyNames)
{
lblMsg.Text+=p.ToString() + ":" + de.Properties[p.ToString()][0].ToString() + "<br/>";
}
}
else
{
Page.ClientScript.RegisterStartupScript(Page.GetType(), "", "<script language=\"javascript\">alert('用户名或密码错误！')</script>");
}
}
}
catch (Exception exc)
{
Page.ClientScript.RegisterStartupScript(Page.GetType(), "", "<script language=\"javascript\">alert('"+exc.Message+"')</script>");
}
}
2.利用API模拟域帐号登录
[DllImport("advapi32.DLL", SetLastError = true)]
public static extern int LogonUser(string lpszUsername, string lpszDomain, string lpszPassword, int dwLogonType, int dwLogonProvider, ref IntPtr phToken);
protected void Page_Load(object sender, EventArgs e)
{
IntPtr admin_token = default(IntPtr);
WindowsIdentity wid_admin = null;
WindowsImpersonationContext wic = null;
//在程序中模拟域帐户登录
if (LogonUser("ultimus", "valmont-as", "Valmont23", 9, 0, ref admin_token) != 0)
{
using (wid_admin = new WindowsIdentity(admin_token))
{
using (wic = wid_admin.Impersonate())
{
}
}
}
}
