Azure AD B2C

composer require socialiteproviders/azureadb2c

Installation & Basic Usage

Please see the Base Installation Guide, then follow the provider specific instructions below.

Add configuration to config/services.php

'azureadb2c' => [
    'client_id' => env('AADB2C_ClientId'),
    'client_secret' => env('AADB2C_ClientSecret'),
    'redirect' => env('AADB2C_RedirectUri'),
    'domain' => env('AADB2C_Domain'),  // {your_domain}.b2clogin.com
    'policy' => env('AADB2C_Policy'),  // such as 'b2c_1_user_susi'
    'default_algorithm' => env('AADB2C_DefaultAlgorithm', 'RS256'), // decoding algorithm JWK key such as 'RS256'
    'custom_domain' => env('AADB2C_CUSTOM_DOMAIN'), // optional - set to use your custom domain e.g. login.contoso.com
    'tenant' => env('AADB2C_TENANT'), // optional - set to use your tenant ID or custom domain in place of the default onmicrosoft.com one
],

To set up your Azure AD B2C custom domain, follow these instructions.

Add provider event listener

Laravel 11+

In Laravel 11, the default EventServiceProvider provider was removed. Instead, add the listener using the listen method on the Event facade, in your AppServiceProvider boot method.

• Note: You do not need to add anything for the built-in socialite providers unless you override them with your own providers.

Event::listen(function (\SocialiteProviders\Manager\SocialiteWasCalled $event) {
    $event->extendSocialite('azureadb2c', \SocialiteProviders\AzureADB2C\Provider::class);
});

Laravel 10 or below

Configure the package's listener to listen for `SocialiteWasCalled` events.

Add the event to your listen[] array in app/Providers/EventServiceProvider. See the Base Installation Guide for detailed instructions.

protected $listen = [
    \SocialiteProviders\Manager\SocialiteWasCalled::class => [
        // ... other providers
        \SocialiteProviders\AzureADB2C\AzureADB2CExtendSocialite::class.'@handle',
    ],
];

Usage

You should now be able to use the provider like you would regularly use Socialite (assuming you have the facade installed):

Redirect to Azure AD B2C

return Socialite::driver('azureadb2c')->redirect();

Callback

$provided_user = Socialite::driver('azureadb2c')->user();

Logout

return redirect(Socialite::driver('azureadb2c')->logout('http://localhost'));

Returned User fields

• sub
• name

Note) If you want to add claim mappings, change User::setRaw() function. The claims mappings must be match with claims in id_token which Azure AD B2C returns.

    public function setRaw($user)
    {
        $user['name'] = $user['name'] ?: $user['given_name'].' '.$user['family_name'];
        $user['nickname'] = $user['name'] ?: '';
        $user['email'] = $user['emails'][0];

        return parent::setRaw($user);
    }
