Installation

This Magento2 module can be installed using composer:
> composer require wika-group/magento2-azure-ad-b2c-sso

To remove it from the list of required packages use the following command:
> composer remove wika-group/magento2-azure-ad-b2c-sso

Updating to latest version

With the following command composer checks all packages in the composer.json for the latest version:
> composer update

If you only want to check this package for newer versions, you can use
> composer update wika-group/magento2-azure-ad-b2c-sso

Configuration

The configuration can be found in the admin backend under:
Stores -> Settings -> Configuration -> WIKA GROUP -> Azure B2C

If you do not want to use the provided button, you can disable it with the "Show button" setting.
To trigger the redirect to Azure for the login, call the route <your-domain>/azureb2c/login/authorize.
The response will be processed from the controller <your-domain>/azureb2c/login/callback.

Autologin after registration in B2C

The first time a customer is registrating on the shop, the redirect after the registration takes them back to the shop.
But the shop doesn't know that the user is logged in. For this scenario, a GET parameter can be used to automatically redirect the user to the login again.
As the customer is already logged in in B2C, no input is required and a redirect will lead back to the shop, but now the customer will also be logged in to the shop.

Log out from Azure B2C

In the admin backend, you can enable logout from Azure B2C after the customer has logged out from Magento.
The observer for the customer_logout_after event will check if the logout from Azure B2C is enabled and will redirect to the logout URI from Azure B2C.

Call authorize with referer

By default the authorize controller will read the referer from the request header, store it in the session and redirect back to it in the callback controller.

You can pass a referer as GET parameter to customize the redirect:
<your-domain>/azureb2c/login/authorize?referer=<your-customer-referer-uri>

Events

customer_login

Observers for the event customer_login will be triggered if a customer uses Azure B2C to login.

customer_logout_after

The extension adds an additional event after the Session model executed the logout logic.
customer_logout is a default event triggered by the Session model before the logout is done.
customer_logout_after is triggered after the logout logic in the Session::logout function is executed.

azure_b2c_sso_[create|update]_customer_after

The extension triggers an event after a new customer was created and after a customer has been updated.

The event azure_b2c_sso_create_customer_after is triggered after this module created a new magento customer.

The event azure_b2c_sso_update_customer_after is triggered after this module updated a magento customer. The update also happends after a customer was created.
