ASP.NET MVC et authentification de connexion

J'ai recherché de nombreux messages ici concernant l'authentification personnalisée de l'utilisateur, mais aucun n'a adressé toutes mes préoccupations

Je suis nouveau sur ASP.NET MVC et avez utilisé traditionnel ASP.NET (WebForms) mais ne sais pas comment construire un Mécanisme de connexion / authentification pour un utilisateur utilisant ASP.NET MVC. P>

protected void Login1_Authenticate(object sender, AuthenticateEventArgs e)
{
    string userName = Login1.UserName;
    string password = Login1.Password;
    bool rememberUserName = Login1.RememberMeSet;

    if (validateuser(userName, password))
    {
        //Fetch the role
        Database db = DatabaseFactory.CreateDatabase();


        //Create Command object
        System.Data.Common.DbCommand cmd = db.GetStoredProcCommand("sp_RolesForUser");
        db.AddInParameter(cmd, "@Uid", System.Data.DbType.String, 15);
        db.SetParameterValue(cmd, "@Uid", Login1.UserName);
        System.Data.IDataReader reader = db.ExecuteReader(cmd);
        System.Collections.ArrayList roleList = new System.Collections.ArrayList();
        if (reader.Read())
        {
            roleList.Add(reader[0]);
            string myRoles = (string)roleList[0];

            //Create Form Authentication ticket
            //Parameter(1) = Ticket version
            //Parameter(2) = User ID
            //Parameter(3) = Ticket Current Date and Time
            //Parameter(4) = Ticket Expiry
            //Parameter(5) = Remember me check
            //Parameter(6) = User Associated Roles in this ticket
            //Parameter(7) = Cookie Path (if any)
            FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(1, userName, DateTime.Now,
            DateTime.Now.AddMinutes(20), rememberUserName, myRoles, FormsAuthentication.FormsCookiePath);

            //For security reasons we may hash the cookies
            string hashCookies = FormsAuthentication.Encrypt(ticket);
            HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName, hashCookies);

            // add the cookie to user browser
            Response.Cookies.Add(cookie);

            if (HttpContext.Current.User.IsInRole("Administrators"))
            {
                Response.Redirect("~/Admin/Default.aspx");
            }
            else
            {
                string returnURL = "~/Default.aspx";

                // get the requested page
                //string returnUrl = Request.QueryString["ReturnUrl"];
                //if (returnUrl == null)
                //   returnUrl = "~/Default.aspx";
                Response.Redirect(returnURL);
            }
        }
    }
}

  protected bool validateuser(string UserName, string Password)
  {
    Boolean boolReturnValue = false;

    //Create Connection using Enterprise Library Database Factory
    Database db = DatabaseFactory.CreateDatabase();

    //Create Command object
    DbCommand cmd = db.GetStoredProcCommand("sp_ValidateUser");

    db.AddInParameter(cmd, "@userid", DbType.String, 15);
    db.SetParameterValue(cmd, "@userid", Login1.UserName);

    db.AddInParameter(cmd, "@password", DbType.String, 15);
    db.SetParameterValue(cmd, "@password", Login1.Password);

    db.AddOutParameter(cmd, "@retval", DbType.Int16, 2);
    db.ExecuteNonQuery(cmd);

    int theStatus = (System.Int16)db.GetParameterValue(cmd, "@retval");

    if (theStatus > 0)  //Authenticated user
        boolReturnValue = true;
    else  //UnAuthorized...
        boolReturnValue = false;

    return boolReturnValue;
