Drupal Laravel SSO Login with OAuth Client | Drupal Laravel Login

Drupal Laravel SSO integration will allow you to configure Single Sign-On ( SSO ) login between your Drupal site and Laravel using OAuth/OpenID protocol. Drupal OAuth 2.0/OpenID connect module gives the ability to enable login using OAuth 2.0/OIDC Single Sign-On to Drupal Site. We provide the Drupal OAuth/OpenID Client module for Drupal 7, Drupal 8, and Drupal 9.
Here we will go through a guide to configure the SSO login between Drupal and Laravel. By following these steps, users of Laravel will be able to log into the Drupal site using their Laravel credentials.
If you have any queries or if you need any sort of assistance in configuring the module, you can contact us at drupalsupport@xecurify.com. If you want, we can also schedule an online meeting to help you configure the Drupal OAuth & OpenID Connect Login - OAuth2 Client SSO Login module.

2. Configure SSO Application in Laravel

• Create a laravel project on your local machine using command and set it up:

composer create-project --prefer-dist laravel/laravel blog

• Change the directory to blog using cd blog command. Install laravel passport

composer require laravel/passport

• Go to config/app.php and add below provider

Laravel\Passport\PassportServiceProvider::class

• Run php artisan migrate command
• Run php artisan passport:install command
• Go to app/User.php model class, add HasApiTokens trait to the code:

     
    namespace App;
    use Laravel\Passport\HasApiTokens;
    use Illuminate\Contracts\Auth\MustVerifyEmail;
    use Illuminate\Foundation\Auth\User as Authenticatable;
    use Illuminate\Notifications\Notifiable;
     
    class User extends Authenticatable
    {
      use HasApiTokens, Notifiable;
     
      
        /**
         * The attributes that are mass assignable.
         *
         * @var array
        */
        protected $fillable = [
            'name', 'email', 'password',
        ];
     
        /**
         * The attributes that should be hidden for arrays.
         *
         * @var array
         */
        protected $hidden = [
            'password', 'remember_token',
        ];
     
        /**
         * The attributes that should be cast to native types.
         *
         * @var array
         */
       
        protected $casts = [
            'email_verified_at' => 'datetime',
        ];
    }
    
    
    

• Go to app/Providers/AuthServiceProvider.php, add use Laravel\Passport\Passport; , Passport::routes(); routes to the service code is given below:

    
    namespace App\Providers;
    use Laravel\Passport\Passport;
    use Illuminate\Foundation\Support\Providers\AuthServiceProvider as ServiceProvider;
    use Illuminate\Support\Facades\Gate;
     
    class AuthServiceProvider extends ServiceProvider
    {
    
        /**
         * The policy mappings for the application.
         *
         * @var array
         */
        protected $policies = [
            // 'App\Model' => 'App\Policies\ModelPolicy',
        ];
     
        /**
         * Register any authentication / authorization services.
         *
         * @return void
         */
        public function boot()
        {
            $this->registerPolicies();
            Passport::routes();
            //
        }
    }
    

• Go to config/auth.php change the api driver token to passport as we are going to use Passport library.

    'guards' => [
            'web' => [
                'driver' => 'session',
                'provider' => 'users',
            ],
            'api' => [
                'driver' => 'passport',
                'provider' => 'users',
                'hash' => false,
            ],
        ],
    

• To create a UserInfo endpoint manually, in the app/Http/Controllers, create a file UserController.php:

                            <?php
                            namespace App\Http\Controllers;
                            use App\Http\Controllers\Controller;
                            use Illuminate\Http\Request;
                            use App\Models\User;
                            use Auth;
                            class UserController extends Controller
                            {
                                public function get(Request $request)
                                {
                                $user_id = Auth::id();
                                $user = User::find($user_id);
                                return $user;
                                }
                            }
                        

• Also, register the API route by adding the below line in routes/api.php file:

    //For Laravel below 8 and migrated to the 8 version:
    Route::middleware('auth:api')->get('/user/get', 'UserController@get');
     

OR

    //For Laravel 8 new users:
    use App\Http\Controllers\UserController;                                                                       
     Route::middleware('auth:api')->get('/user/get', 'App\Http\Controllers\UserController@get');
