I am trying to connect Eloquent to multiple databases sqlserver for the default and mongodb for the secondary connection. I am using jenssegers/laravel-mongodb pulled in using composer. Here is my database file

```
use Illuminate\Database\Capsule\Manager as Capsule;

$capsule = new Capsule;

$capsule->addConnection([
        'driver'   => 'sqlsrv',
        'host'     => '******',
        'database' => '*****',
        'username' => '*****',
        'password' => '*****',
        'prefix'   => '',
    ], 'default');

$capsule->addConnection([
        'driver'   => 'mongodb',
        'host'     => 'localhost',
        'port'     => 27017,
        'username' => '',
        'password' => '',
        'database' => 'production'
], 'mongo');

$capsule->setAsGlobal();
$capsule->bootEloquent();

```

The problem is when i try and connect to the mongo database it throws the following error:

```
InvalidArgumentException thrown with message "Unsupported driver [mongodb]"

```

It looks to me that the Illuminate connection factory does not support mongodb out of the box, could someone please point me in the right direction to get this working?
