Laravel 4 chain authentication provider

WARNING: Project no longer maintaned!

Supports native database, LDAP, IMAP and IP address multi-domain authentication for single sign-on.

For LDAP and IMAP authentication you need to have ldap and imap php extensions.

Installation

Installing this package through Composer. Edit your project's composer.json file to require restricted/authchain.

"require": {
	"laravel/framework": "4.2.*",
	"restricted/authchain": ">=1.0.6"
}

Update Composer from the Terminal:

composer update

Once this operation completes, the next step is to add the service provider. Open app/config/app.php, and add a new item to the providers array.

'providers' => [
    // Your Laravel providers here...
    'Restricted\Authchain\AuthchainServiceProvider'
]

Create example configuration file from terminal:

php artisan config:publish restricted/authchain

Change default authentication provider to authchain.

Open app/config/auth.php and change driver section to authchain.

return array(

	'driver': 'authchain'

	// Related stuff...
);

Please see app/config/packages/restricted/authchain/config.php for full configuration instructions.

You need to create User model in app/models and create migration.

For details on models and migrations you can see vendor/restricted/authchain/quickstart

You can simply copy contents of folder vendor/restricted/authchain/quickstart/models/ to app/models.

Example migration can be executed by command php artisan migrate --package="restricted/authchain".

NOTE: migration does`t include timestamps.

If you don't use ip address authentication, set ['defaults']['ip'] to false in app/config/packages/restricted/authchain/config.php.

Quickstart

You can easily write your own authentication provider for authchain:

Custom provider example (see in src/Restricted/Authchain/Provider/Domain/CustomProviderExample):

namespace Restricted\Authchain\Provider\Domain;

use Restricted\Authchain\Config\Loader;
use Restricted\Authchain\Provider\Provider;
use Restricted\Authchain\Provider\ProviderInterface;

class CustomProviderExample extends Provider implements ProviderInterface
{
    // Authentication logic
    // $this->username is username provided by user
    // $this->password is password from form

    // @return UserInterface|null

    public function authenticate()
    {
    	// Loading users from config for domain $this->domain
    	
        $users = Loader::domain($this->domain)['users'];

	// If user not found in array, return null
	
        if (!isset($users[$this->username])) {
            return null;
        }
	
	// Grab user password from config

        $password = $users[$this->username];

	// Check password

        if (\Hash::check($this->password, $password)) {
        
            $newUser                       = $this->model();
            $newUser->{Loader::username()} = $this->username;
            $newUser->{Loader::password()} = \Hash::make($password);
            $newUser->enabled              = true;

            $newUser->save();

            return $newUser;
        }

        return null;
    }
    
    // Must return name of the provider, for example 'custom'
    // In app/config/packages/restricted/authchain/config.php
    // you can regiter new provider in 'providers' array and pass config variables to it

    public function provides()
    {
        return 'custom';
    }

}

Create config for custom provider in app/config/packages/restricted/authchain/config.php:

Register custom provider in section providers:

'providers' => array(
    // ...
    'Restricted\Authchain\Provider\Domain\CustomProviderExample',
)

In section domains:

'localhost' => array(
    'provider' => 'custom', // See method provides()
        'users' => array(
            'demo@localhost' => '$2y$10$/Ij0dzDL49OaODli.1GcveefSdEapt2vgb8shplVI7RIJadPmL6km' // Encrypted password
    )
)

Now, all users with domain localhost authenticates over custom provider and native provider (Eloquent).
