asp.net – 检查Active Directory密码是否与cookie不同

我有一个asp.net应用程序需要使用表单身份验证将用户登录到Active Directory(Windows身份验证不是具有给定要求的选项).

我正在保存身份验证cookie,如下所示：

if (Membership.ValidateUser(model.UserName,model.Password))
{
    FormsAuthentication.SetAuthCookie(model.UserName,model.RememberMe);
}

这非常有效,除非cookie在更改其Active Directory密码后对用户进行身份验证.

有没有办法判断用户的密码是否已更改？

我在.NET 4中使用asp.net MVC3

我试过的

如果觉得这个代码应该有效,那么HttpWebResponse永远不会包含任何cookie.不太确定我做错了什么.

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Request.Url);
request.CookieContainer = new CookieContainer();

HttpWebResponse response = (HttpWebResponse)request.GetResponse();

Cookie authCookie = response.Cookies["AuthCookie"];
if (authCookie.TimeStamp.Compareto(Membership.GetUser().LastPasswordChangedDate) < 0)
{
    authCookie.Expired = true;
}

解决方法

你的代码应该阅读

if (Membership.ValidateUser(model.UserName,model.Password))
{
  string userData = DateTime.Now.ToString();

  FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(1,username,DateTime.Now,DateTime.Now.AddMinutes(30),isPersistent,userData,FormsAuthentication.FormsCookiePath);

  // Encrypt the ticket.
  string encTicket = FormsAuthentication.Encrypt(ticket);

  // Create the cookie.
  Response.Cookies.Add(new HttpCookie(FormsAuthentication.FormsCookieName,encTicket));
}

现在,在验证用户时

HttpCookie authCookie = Request.Cookies[FormsAuthentication.FormsCookieName];
FormsAuthenticationTicket ticket = FormsAuthentication.Decrypt(authCookie.value);
if (DateTime.Parse(ticket.UserData) > Membership.GetUser().LastPasswordChangedDate)
{
    FormsAuthentication.SignOut();
    FormsAuthentication.RedirectToLoginPage();
}
