Symfony bundle for Azure AD Delta Sync flow.


To install run

composer require itk-dev/azure-ad-delta-sync-bundle


Before being able to use the bundle, you must have your own User entity, UserRepository and database setup.

You will need to configure variables for Microsoft groups, the above mentioned User entity and cache pool:

Variable configuration

In /config/packages you need the following itkdev_azure_ad_delta_sync.yaml file:

    tenant_id: 'some_tenant_id'
    client_id: 'some_client_id'
    client_secret: 'some_client_secret'
    group_id: 'some_group_id'
    system_user_class: 'App\Entity\User'
    system_user_property: 'some_user_property'
    azure_ad_user_property: 'some_azure_ad_user_property'
    cache_pool: ''

Here the azure_ad_user_property should be a property on the Azure AD user that is equivalent to the system_user_property, as this is how we compare system users with Microsoft group users. For this reason the comparing property must also be unique.

Listening to DeleteUserEvent

The bundle dispatches a DeleteUserEvent containing a list of user properties (system_user_property) for potential removal. The using system should implement logic to ensure these users are not deleted unintentionally.

Therefore, the using system will need to implement an EventListener or EventSubscriber that listens to the DeleteUserEvent.

Example EventSubscriber


namespace App\EventSubscriber;

use ItkDev\AzureAdDeltaSyncBundle\Event\DeleteUserEvent;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;

class DeleteUserEventSubscriber implements EventSubscriberInterface

    public static function getSubscribedEvents(): array
        return [
            DeleteUserEvent::class => 'deleteUsers',

    public function deleteUsers(DeleteUserEvent $event)
        // User deletion logic here

Starting the flow

To start the flow the using system execute the follow CLI command:

php bin/console delta-sync:run

It is up to the using system to decide how and when to run this command.

Development Setup

A docker-compose.yml file with a PHP 7.4 image is included in this project. To install the dependencies you can run

docker compose up -d
docker compose exec phpfpm composer install

Unit Testing

We use PHPUnit for unit testing. To run the tests:

docker compose exec phpfpm composer install
docker compose exec phpfpm ./vendor/bin/phpunit tests

The test suite uses Mocks for generation of test doubles.

Check Coding Standard

  • PHP files (PHP_CodeSniffer)

    docker compose exec phpfpm composer check-coding-standards
  • Markdown files (markdownlint standard rules)

    docker run -v ${PWD}:/app itkdev/yarn:latest install
    docker run -v ${PWD}:/app itkdev/yarn:latest check-coding-standards

GitHub Actions

All code checks mentioned above are automatically run by GitHub Actions when a pull request is created.

To run the actions locally, install act and run

act -P ubuntu-latest=shivammathur/node:focal pull_request

Use act -P ubuntu-latest=shivammathur/node:focal pull_request --list to see individual workflow jobs that can be run, e.g.

act -P ubuntu-latest=shivammathur/node:focal pull_request --job phpcsfixer

Apply Coding Standards

  • PHP files (PHP_CodeSniffer)

    docker compose exec phpfpm composer apply-coding-standards
  • Markdown files (markdownlint standard rules)

    docker run -v ${PWD}:/app itkdev/yarn:latest install
    docker run -v ${PWD}:/app itkdev/yarn:latest apply-coding-standards
