Trying to change the default minimum password length to 4 characters. I know, 4!!! Ridiculous, right! Not my call.

Anyway, I've changed it on the `RegisterViewModel` but that doesn't actually change it. To illustrate I've posted the code below. The `ModleState.IsValid` returns correctly based on the updated ViewModel. However it then calls `UserManager.CreateAsync()` which returns `False` with an error message of "Passwords must be at least 6 characters"

I've followed the steps in this, very, similar post([Change Password...](https://stackoverflow.com/questions/14721378/change-password-length-in-membership-api)) but it does not work for MVC 5 as far I as I can tell. It still returns the same message.

```
//
    // POST: /Account/Register
    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public async Task<ActionResult> Register(RegisterViewModel model)
    {
        if (ModelState.IsValid)
        {
            var user = new ApplicationUser() { UserName = model.UserName, LastLogin = model.LastLogin };

// This is where it 'fails' on the CreateAsync() call
                    var result = await UserManager.CreateAsync(user, model.Password);
                    if (result.Succeeded)
                    {
                        await SignInAsync(user, isPersistent: false);
                        return RedirectToAction("Index", "Home");
                    }
                    else
                    {
                        AddErrors(result);
                    }
                }
            // If we got this far, something failed, redisplay form
            return View(model);
        }

```
