Laravel Auth using Third Party Authentication

I am building an application that is using a third party authentication database. I have created a custom composer package to "intercept" the POST request to /login. Everything is working great - I'm able to get a user object back and save it to my (laravel) database.

I am now at the point where I want to redirect to the home page and do "stuff". I would like to use Laravel's native Auth as much as possible if I can.

For example, on the home page I am doing this:

$foo = auth()->user()->foo->where('active', 1);

No surprise, since I am not using Laravel's native Auth method, auth()->user() is returning null. Once I have my user created/found in my database, is it possible to tie back into Laravel's auth() methods?

Thank you for any suggestions!

EDIT

Reading the documentation, this looks like the direction I need to go but I'm falling short understanding how to connect/register my custom package (I think)...

EDIT 2

I am going to keep updating this as I feel I make any progress in hopes that it will not only help me, but help others get a better picture of what I am trying to accomplish. Ultimately help others who may be trying to do the same.

I have updated my app/Providers/AuthServiceProviderAuthServiceProvider as such:

use My\Package\MyThirdPartyServiceProvider;


...


Auth::provider('foo', function ($app, array $config) {
        // Return an instance of Illuminate\Contracts\Auth\UserProvider...

    return new MyThirdPartyServiceProvider($app->make('foo.connection'));
});

I have also updated my config/auth file:

'providers' => [
    'users' => [
        'driver' => 'foo',
        'model' => App\User::class,
    ]

As you mentioned the documentation suggests implementing a custom user provider. The following steps more or less describe how you'll tackle it in a bit more detail.

  1. Create or edit a service provider You can create a new service provider by running

php artisan make:provider CustomAuthServiceProvider

  1. In the boot method of your service provider you'll have to configure our auth provider (which will be implemented in step 4).
    public function boot()
    {
        Auth::provider('custom-auth', function ($app, array $config) {
            return new CustomAuthProvider();
        });
    }
  1. Update your auth.php configuration to use the serviceprovider we registered in step 2 
'providers' => [
    'users' => [
        'driver' => 'custom-auth',
    ],
],
  1. Create the CustomAuthProvider class itself and implement the UserProvider interface
class CustomAuthProvider implements UserProvider
{
    public function retrieveById($identifier) {
        // Retrieve a user by their unique identifier.
    }

    public function retrieveByToken($identifier, $token) {
        // Retrieve a user by their unique identifier and "remember me" token.
    }

    public function updateRememberToken(Authenticatable $user, $token) {
        // Update the "remember me" token for the given user in storage.
    }

    public function retrieveByCredentials(array $credentials) {
        // Retrieve a user by the given credentials.
    }

    public function validateCredentials(Authenticatable $user, array $credentials) {
        // Validate a user against the given credentials.
    }
}
