在选择AD登录时，其实可以直接选择 Windows 授权，不过因为有些网站需要的是LDAP获取信息进行授权，而非直接依赖Web Server自带的Windows 授权功能。
当然如果使用的是Azure AD/企业账号登录时，直接在ASP.NET Core创建项目时选择就好了。
来个ABC：
新建一个ASP.NET Core项目
Nuget引用dependencies / 修改```project.json```
Novell.Directory.Ldap.NETStandard
Microsoft.AspNetCore.Authentication.Cookies
版本如下：
"Novell.Directory.Ldap.NETStandard": "2.3.5",
"Microsoft.AspNetCore.Authentication.Cookies": "1.1.0"
本文的AD登录使用的是第三方的
```Novell.Directory.Ldap.NETStandard``` 进行的LDAP操作（还没有看这个LDAP的库是否有安全性问题，如果有需要修改或更换）
建立一个LDAP操作的工具类
代码在下面链接中，就不单独贴了，基本上就2个方法：
Register是获取基本配置信息的
Validate是来验证用户名密码的
using System;
using Microsoft.Extensions.Configuration;
using Novell.Directory.Ldap;
namespace Demo
{
public class LDAPUtil
{
public static string Host { get; private set; }
public static string BindDN { get; private set; }
public static string BindPassword { get; private set; }
public static int Port { get; private set; }
public static string BaseDC { get; private set; }
public static string CookieName { get; private set; }
public static void Register(IConfigurationRoot configuration)
{
Host = configuration.GetValue<string>("LDAPServer");
Port = configuration?.GetValue<int>("LDAPPort") ?? 389;
BindDN = configuration.GetValue<string>("BindDN");
BindPassword = configuration.GetValue<string>("BindPassword");
BaseDC = configuration.GetValue<string>("LDAPBaseDC");
CookieName = configuration.GetValue<string>("CookieName");
}
public static bool Validate(string username, string password)
{
try
{
using (var conn = new LdapConnection())
{
conn.Connect(Host, Port);
conn.Bind($"{BindDN},{BaseDC}", BindPassword);
var entities =
conn.Search(BaseDC,LdapConnection.SCOPE_SUB,
$"(sAMAccountName={username})",
new string[] { "sAMAccountName" }, false);
string userDn = null;
while (entities.hasMore())
{
var entity = entities.next();
var account = entity.getAttribute("sAMAccountName");
//If you need to Case insensitive, please modify the below code.
if (account != null && account.StringValue == username)
{
userDn = entity.DN;
break;
}
}
if (string.IsNullOrWhiteSpace(userDn)) return false;
conn.Bind(userDn, password);
// LdapAttribute passwordAttr = new LdapAttribute("userPassword", password);
// var compareResult = conn.Compare(userDn, passwordAttr);
conn.Disconnect();
return true;
}
}
catch (LdapException)
{
return false;
}
catch (Exception)
{
return false;
}
}
}
}
在applicationSettings.json中添加基本的域配置
"LDAPServer": "192.168.1.1",//域服务器
"LDAPPort": 389,//端口，一般默认就是这个
"CookieName": "testcookiename",//使用Cookie登录的Cookie的Key
"BindDN": "CN=DoWebUser,CN=Users",//用来获取LDAP的信息用户的用户名
"BindPassword": "!DoWebUserPassword",//用来获取LDAP的信息的用户的密码，即DoWebUser的密码
"LDAPBaseDC": "DC=aspnet,DC=com",//域的DC
Startup.cs中修改
Startup方法中：
LDAPUtil.Register(Configuration);
ConfigureServices 方法中：
services.AddAuthorization(options =>{});
Configure方法中：
app.UseCookieAuthentication(new CookieAuthenticationOptions()
{
AuthenticationScheme = Configuration.GetValue<string>("CookieName"),
LoginPath = new PathString("/Account/Login/"),
AccessDeniedPath = new PathString("/Account/Login/"),
AutomaticAuthenticate = true,
AutomaticChallenge = true
});
AccountController中添加登录和注销的Action
登录的页面：
[AllowAnonymous]
public IActionResult Login()
{
return View();
}
登录的Post页面：
[HttpPost]
[AllowAnonymous]
public async Task<IActionResult> Login(string u, string p)
{
if (LDAPUtil.Validate(u, p))
{
var identity = new ClaimsIdentity(new MyIdentity(u));//这个MyIdentity只是一个祼的IIdentity的实现的类
var principal = new ClaimsPrincipal(identity);
await HttpContext.Authentication.SignInAsync(LDAPUtil.CookieName, principal);
return RedirectToAction("Index", "Home");
}
return View();
}
注销的页面：
[Authorize]
public async Task<IActionResult> Logout()
{
await HttpContext.Authentication.SignOutAsync(LDAPUtil.CookieName);
return RedirectToAction("Index", "Home");
}
