Use the Sentinel 2.x authentication package with Laravel 5.1 and MongoDB

laravel-mongodb-sentinel

Work in Progress: More testing to be done.
At a glance Authentication, Activation, Throttle, Groups & Permissions seem to 
be working.

Downside: Copy and modify files.
Upside: Not really much work to get it up and running.

Assumes you have Laravel 5.1, jenssegers/laravel-mongodb + session addon set up
and your app is namespaced to App/

Install Sentinel 2.x and publish the configuration as per their instructions.

Because Sentinel models use the default Eloquent Model, we will need to copy 
these and modify to use the MongoDB Model.

Copy the following vendor model files
-------------------------------------------------------------------------
\vendor\cartalyst\sentinel\src\Activations\EloquentActivation.php
\vendor\cartalyst\sentinel\src\Persistences\EloquentPersistence.php
\vendor\cartalyst\sentinel\src\Reminders\EloquentReminder.php
\vendor\cartalyst\sentinel\src\Roles\EloquentRole.php
\vendor\cartalyst\sentinel\src\Throttling\EloquentThrottle.php
\vendor\cartalyst\sentinel\src\Users\EloquentUser.php

To your application folder
-------------------------------------------------------------------------
\app\Sentinel\Activations\EloquentActivation.php
\app\Sentinel\Persistences\EloquentPersistence.php
\app\Sentinel\Reminders\EloquentReminder.php
\app\Sentinel\Roles\EloquentRole.php
\app\Sentinel\Throttling\EloquentThrottle.php
\app\Sentinel\Users\EloquentUser.php

In each of the Model files copied over
-------------------------------------------------------------------------
CHANGE
namespace Cartalyst\Sentinel\...;
TO
namespace App\Sentinel\...;

In each of the Model files copied over
-------------------------------------------------------------------------
CHANGE
use Illuminate\Database\Eloquent\Model;
TO
use Jenssegers\MongoDB\Model;

In the EloquentPersistence.php file add
-------------------------------------------------------------------------
use Cartalyst\Sentinel\Persistences\PersistenceInterface;

In the EloquentRole.php file add
-------------------------------------------------------------------------
use Cartalyst\Sentinel\Roles\RoleInterface;

In the EloquentUser.php file add
-------------------------------------------------------------------------
use Cartalyst\Sentinel\Users\UserInterface;

Update Sentinel Config
-------------------------------------------------------------------------
Now update the published Sentinel config so that all references to models
are using the copied files in you app, example for the user config option:

CHANGE
'model' => 'Cartalyst\Sentinel\Users\EloquentUser'
TO
'model' => 'App\Sentinel\Users\EloquentUser'

At this stage Login/Out will be working if the activation and throttle 
checkpoints are disabled in the configuration. To get the checkpoints 
working we need to modify the ServiceProvider and copy/modify some 
Repository files.

Copy the following vendor files
-------------------------------------------------------------------------
\vendor\cartalyst\sentinel\src\Activations\IlluminateActivationRepository.php
\vendor\cartalyst\sentinel\src\Throttling\IlluminateThrottleRepository.php
\vendor\cartalyst\sentinel\src\Laravel\SentinelServiceProvider.php

To your application folder
-------------------------------------------------------------------------
\app\Sentinel\Activations\IlluminateActivationRepository.php
\app\Sentinel\Throttling\IlluminateThrottleRepository.php
\app\Sentinel\Laravel\SentinelServiceProvider.php

In the IlluminateActivationRepository.php file
-------------------------------------------------------------------------
CHANGE
namespace Cartalyst\Sentinel\Activations;
TO
namespace App\Sentinel\Activations;

ADD
use Cartalyst\Sentinel\Activations\ActivationRepositoryInterface;

Modify the create method by adding
$activation->completed = false; before the save.

In the IlluminateThrottleRepository.php file
-------------------------------------------------------------------------
CHANGE
namespace Cartalyst\Sentinel\Throttling;
TO
namespace App\Sentinel\Throttling;

ADD
use Cartalyst\Sentinel\Throttling\ThrottleRepositoryInterface;

In the SentinelServiceProvider.php file
-------------------------------------------------------------------------
CHANGE
namespace Cartalyst\Sentinel\Laravel;
TO
namespace App\Sentinel\Laravel;

CHANGE
use Cartalyst\Sentinel\Activations\IlluminateActivationRepository;
TO
use App\Sentinel\Activations\IlluminateActivationRepository;

CHANGE
use Cartalyst\Sentinel\Throttling\IlluminateThrottleRepository;
TO
use App\Sentinel\Throttling\IlluminateThrottleRepository;

In the prepareResources method update the paths to the vendor folder to avoid errors.
CHANGE
'/../config/config.php'
TO
'/../../../vendor/cartalyst/sentinel/src/config/config.php'

CHANGE
'/../migrations'
TO
'/../../../vendor/cartalyst/sentinel/src/migrations'

Use the copied and modified Service Provider. In your app config providers
-------------------------------------------------------------------------
CHANGE
'Cartalyst\Sentinel\Laravel\SentinelServiceProvider'
TO
'App\Sentinel\Laravel\SentinelServiceProvider'

Now Authentication, Activation, Throttle, Groups & Permissions should be working.
Remember to add some unique constraints to the roles->slug and users->email or whatever
identifier you go with.
