README

Identity & Access Management as a drop-in Bounded Context, for the FrankenPHP / Symfony / Sylius / DDD stack.

composer require alexandrebulete/ddd-iam-bundle gives a project:

• a User aggregate — email, password, lifecycle, roles;
• authentication against the Sylius back office (IamUserProvider);
• a user CRUD in the admin, with grid, filters and a role editor;
• an append-only audit log of every account change;
• iam:create-super-admin, the CLI that solves the chicken-and-egg problem.

No file to copy, no namespace to rewrite. What a project legitimately differs on is configuration.

Install

composer require alexandrebulete/ddd-iam-bundle

Then, in the application:

# config/routes/iam.yaml
iam:
    resource: '@DddIamBundle/config/routes.php'

# config/packages/security.yaml
security:
    password_hashers:
        AlexandreBulete\DddSymfonyBundle\Security\SecurityUser: 'auto'
    providers:
        app_admin_user_provider:
            id: AlexandreBulete\DddIamBundle\Infrastructure\Security\IamUserProvider
    firewalls:
        admin:
            context: admin
            pattern: '/admin(?:/.*)?$'
            provider: app_admin_user_provider
            form_login:
                login_path: sylius_admin_ui_login
                check_path: sylius_admin_ui_login_check
                default_target_path: sylius_admin_ui_dashboard
            logout:
                path: sylius_admin_ui_logout
                target: sylius_admin_ui_login
    access_control:
        - { path: ^/admin/login, roles: PUBLIC_ACCESS }
        - { path: ^/admin/logout, roles: PUBLIC_ACCESS }
        - { path: ^/admin, roles: ROLE_ADMIN }

Do not declare security.role_hierarchy: the bundle prepends it from iam.roles, and an application-level declaration would win over it.

Then:

bin/console doctrine:migrations:diff && bin/console doctrine:migrations:migrate
bin/console iam:create-super-admin --email=[e-mail]

The bundle ships no migration — it cannot know your database. migrations:diff picks up iam_user and iam_audit_log.

Where the line is

The bundle owns identity, credentials, lifecycle and authorisation. It does not own profile or business data: a phone number, an avatar, a store assignment, a signature block are not IAM.

That is not a limitation, it is the reason the bundle can be shared between projects that have nothing else in common. Anything else goes in a companion aggregate in your own Bounded Context, keyed by UserId, with no cross-context foreign key:

final class StaffMember
{
    private function __construct(
        private(set) StaffMemberId $id,
        private(set) UserId $userId,        // published language, not an association
        private(set) ?StoreCode $storeCode,
    ) {}
}

Provision it by listening to the bundle's events:

#[AsEventListener]
final readonly class ProvisionStaffMemberOnUserCreated
{
    public function __invoke(UserCreated $event): void { /* … */ }
}

firstName / lastName are the deliberate exception: every user list needs a human label.

Extension seams

1. Roles — iam.roles

Roles are an open set, deliberately not a PHP enum. The bundle ships user, admin and super_admin; a project adds to them:

iam:
    roles:
        moderator:
            inherits: ['user']

Additive, not replacing — array_replace on top of the defaults, because Symfony would otherwise drop them the moment you declare one key.

moderator becomes ROLE_MODERATOR, appears in security.role_hierarchy, in the admin form's role checkboxes and in iam:create-super-admin --role. Granting a role nobody declared throws UnknownRoleException at the point of the grant, naming the roles that do exist.

2. Password policy — iam.password_policy

iam:
    password_policy:
        min_length: 12
        require_letters: true
        require_digits: true
        require_mixed_case: false
        require_special_character: false

Rules config cannot express (history, HIBP lookup, per-tenant): implement PasswordPolicyInterface and alias it.

3. Back office — iam.admin

iam:
    admin:
        enabled: true              # false → headless, no Sylius service at all
        grid_limits: [10, 25, 50]

Extending a grid. Re-declare the service id with your own subclass — do not use #[AsDecorator]:

$services->set(UserGrid::class)
    ->class(UserGridWithStatusFilter::class)
    ->args([param('iam.admin.grid_limits')]);

A decorator would leave Sylius's sylius.grid tag on the renamed inner service and the grid would silently disappear from the registry. Re-declaring the id keeps every tag and autoconfiguration.

Adding a column backed by your own data is the one case config does not cover: grid fields are read off UserResource, which is final. You need either your own resource + grid pair, or iam.user_class.

4. Audit — iam.audit

iam:
    audit:
        enabled: true

Disabled means absent — no listener, no write. The iam_audit_log table stays mapped either way: dropping history because a flag flipped is not a thing a bundle should do.

Events are published through DomainEventPublisherInterface. The default adapter dispatches in-process, inside the aggregate's transaction. A project running a transactional outbox binds its own adapter and the bundle neither knows nor cares:

$services->alias(DomainEventPublisherInterface::class, OutboxEventPublisher::class);

5. Domain events

UserCreated, UserRenamed, UserEmailChanged, UserPasswordChanged, UserRolesChanged, UserSuspended, UserReactivated, UserRevoked.

Public and stable. UserPasswordChanged deliberately carries no password; UserRolesChanged carries both the new and the previous set, because the delta cannot be recomputed after the fact.

6. Table names — iam.table_prefix

iam:
    table_prefix: iam_

Applied at mapping-load time by TablePrefixListener — a bundle cannot ship a configurable table name in static XML.

7. The escape hatch — iam.user_class

Subclassing the aggregate. Properties are protected(set) and the constructor is protected to make it possible, but overriding this means shipping your own Doctrine mapping for the subclass, and the bundle then maps only the audit log.

Prefer the companion aggregate. This exists for the case that genuinely cannot be modelled that way.

Design notes worth knowing

Roles are stored as JSON, not a join table. They are read on every request, always loaded and written whole, and never queried from the role side. A join table would buy referential integrity against a role table that does not exist — the catalogue lives in configuration.

Deleting a user revokes it. The back office's delete button dispatches RevokeUserCommand. Erasing the row would leave the audit trail pointing at nothing. GDPR erasure is a different use case: scrub the personal data, keep the identifier.

Account status is checked in the user provider, not in a UserChecker. A UserChecker is more idiomatic and discloses less, but it has to be wired per firewall and a firewall that forgets it authenticates suspended accounts silently. For a bundle, a check that cannot be forgotten wins. Revisit the day post-authentication checks appear (password expiry, MFA enrolment).

Route names are pinned via AsResource(alias: 'iam.user') → iam_admin_user_index. Derived names would change under anyone who moved a class.

Configuration reference

iam:
    user_class: AlexandreBulete\DddIamBundle\Domain\Model\User
    table_prefix: iam_
    roles:
        # merged on top of user / admin / super_admin
        moderator: { inherits: ['user'] }
    default_roles: ['user']
    super_admin_role: super_admin
    password_policy:
        min_length: 12
        require_letters: true
        require_digits: true
        require_mixed_case: false
        require_special_character: false
    audit:
        enabled: true
    admin:
        enabled: true
        grid_limits: [10, 25, 50]

Not configurable (yet), and why

The /admin route prefix. It is fixed in #[AsResource], and it matches sylius/admin-ui's own prefix, which the application sets in config/routes/sylius_admin_ui.yaml. Making one side configurable without the other would produce a half-moved back office. Change both, or neither.
