I have searched many posts here regarding custom user authentication but none have addressed all of my concerns

I am new to ASP.NET MVC and have used traditional ASP.NET (WebForms) but don't know how build a login / authentication mechanism for a user using ASP.NET MVC.

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;
}

I don't really know how to translate that ASP.NET code into MVC-esque architecture; and I'm still at a loss on how to implement authentication in ASP.NET MVC.

What do I need to do? How do I implement the above code in ASP.NET MVC? What am I missing from that code?
