Laravel 5.6 - 在自定义表上使用内置Auth - 不验证用户/密码

I am struggling with using Laravel's built-in auth against an existing 'Users' table that already contains username and password. The column names are 'UserEmail' and 'UserPassword'. To test it out, I used tinker to create an entry, hashing the password as:


When trying to log in using Auth::attempt, authentication keeps failing. To debug, I started adding var_dump and even do a comparison of the password request that comes through against the hashed password in the database and it matches. So I am not sure why the Auth::attempt fails to authenticate it:

This is the function I have in my LoginController.php:

public function login(Request $request)
    // validate the form data
    $this->validate($request, [
        'UserEmail' => 'required',
        'UserPassword' => 'required'

    $user = App\FarmUser::where('UserEmail', $request->UserEmail)->first();
    $authenticated = Hash::check($request->UserPassword, $user->UserPassword);

    // attempt to log the user in
    if (Auth::attempt(['UserEmail' => $request->UserEmail, 'UserPassword' => $request->UserPassword], $request->remember)) {
        // if successful, then redirect to their intended location
        Debugbar::addMessage('successfully authenticated');
        return redirect()->intended($redirectTo);   

    // if unsuccessful, then redirect back to login with the form data
    Debugbar::addMessage('authentication failed');
    //return redirect()->back();

When I try to log in, I see the correct UserEmail, UserPassword, and the hash check also returns true. However, when I call the Auth::attempt, it does not successfully authenticate and redirects back. Any idea why I can't get the Auth::attempt to authenticate properly?

When I log in, this is the output generated from those var dumps:

string(20) "" string(8) "1234" string(60) "<hash>" bool(true)

Here is what tinker returns for this App\FarmUser model:

>>> $user = App\FarmUser::where('UserLogin', 'testuser')->first();
=> App\FarmUser {#809
     ID: 1,
     UserLogin: "testuser",
     password: "<hash>",
     Active: "Yes",
     UserEmail: "",
     Created: "2018-03-20 15:09:24",
     CreatedByID: null,
     Modified: null,
     ModifiedByID: null,
     created_at: "2018-03-20 19:09:09",
     updated_at: "2018-03-20 19:09:09",
