v2.9.0 2023-01-12 15:00 UTC


This bundle can be used to add OIDC support to any Symfony application. We have only tested it with SURFconext OIDC, but it should work with any OIDC provider!

Many thanks to https://github.com/jumbojett/OpenID-Connect-PHP for the implementation which this bundle uses although it has been modified to fix within an object oriented approach.

Note that this repository is automatically mirrored from our own Gitlab instance. We will accept issues and merge requests here though!

Version notes

Version 2 of this bundle only supports Symfony's new authentication manager, introduced in Symfony 5.3. As the security manager matured in Symfony 5.4, that is the first version this bundle supports. Using the new authentication manager is required for Symfony 6!

We also require the use of PHP8, as that significantly reduces the maintenance complexity.

Do you need this bundle, but you cannot enable the new authentication manager or use PHP8? Check out the v1.x branch and its documentation!

Migrate from v1.x

Take a look at UPGRADE.md!


You can add this bundle by simply requiring it with composer:

composer require drenso/symfony-oidc-bundle

If you're using Symfony Flex, your .env file should have been appended with some environment variables and a drenso_oidc.yaml file should have been created in your configuration directory!


OIDC Clients

Make sure to configure at least the default OIDC client in the drenso_oidc.yaml in your config/packages directory. This can be done using the environment variables already added to your application by Symfony flex, or by updating the configuration file. You can configure more clients, they will be available under the drenso.oidc.client.{name}, and are autowirable by using OidcClientInterface ${name}OidcClient, for example OidcClientInterface $defaultOidcClient. If the name does not match with one of the configured clients, the default client will be autowired.

Configuration example:

    #default_client: default # The default client, will be aliased to OidcClientInterface
        default: # The client name, each client will be aliased to its name (for example, $defaultOidcClient)
            # Required OIDC client configuration
            well_known_url: '%env(OIDC_WELL_KNOWN_URL)%'
            client_id: '%env(OIDC_CLIENT_ID)%'
            client_secret: '%env(OIDC_CLIENT_SECRET)%'

            # Extra configuration options
            #well_known_parser: ~ # Service id for a custom well-known configuration parser
            #well_known_cache_time: 3600 # Time in seconds, will only be used when symfony/cache is available
            #redirect_route: '/login_check'
            #custom_client_headers: []
            #code_challenge_method: ~ # Code challenge method, can be null, 'S256' or 'plain'
            #disable_nonce: false # Set to true when nonce verification should not be used

        # Add any extra client
        #link: # Will be accessible using $linkOidcClient
            #well_known_url: '%env(LINK_WELL_KNOWN_URL)%'
            #client_id: '%env(LINK_CLIENT_ID)%'
            #client_secret: '%env(LINK_CLIENT_SECRET)%'
User provider

You will need to update your User Provider to implement the methods from the OidcUserProviderInterface. Two methods need to be implemented:

  • ensureUserExists(string $userIdentifier, OidcUserData $userData): Implement this method to bootstrap a new account using the data available from the passed OidcUserData object. The identifier is a configurable property from the user data, which defaults to sub. If the account cannot be bootstrapped, authentication will be impossible as the User Provider will not be capable of retrieving the user.
  • loadOidcUser(string $userIdentifier): UserInterface: Implement this method to retrieve the user based on the identifier. We use a dedicated method instead of Symfony's default loadUserByIdentifier to allow you to detect where the login is coming from, without the need of creating a dedicated user provider. If the OIDC user identifiers are unique, a forward to the loadUserByIdentifier should be sufficient.
Firewall configuration

If you are using Symfony <6, make sure to enable the new authentication manager in the security.yaml:

  enable_authenticator_manager: true

Enable the oidc listener in the security.yml for your firewall:

      pattern: ^/
      oidc: ~

There are a couple of options available for the oidc listener.

Option Default Description
check_path /login_check Only on this path the authenticator will accept authentication. Note that this should match with the redirect configured for the OIDC client.
login_path /login The path to forward to when authentication is required
client default The configured OIDC client to use
user_identifier_property sub The OidcUserData property to use as unique user identifier
enable_remember_me false Enable "remember me" functionality for authenticator
enable_end_session_listener false Enable "logout" functionality for authenticator through the "LogoutEvent"
use_logout_target_path true Used for the end session event subscriber
always_use_default_target_path false Used for the success handler
default_target_path / Used for the success handler
target_path_parameter _target_path Used for the success handler
use_referer false Used for the success handler
failure_path null Used for the failure handler
failure_forward false Used for the failure handler
failure_path_parameter _failure_path Used for the failure handler

You can configure them directly under the oidc listener in your firewall, for example the user_identifier_property:

        user_identifier_property: email
Start the authentication

Use the controller example below to forward a user to the OIDC service:

   * This controller forwards the user to the OIDC login
   * @throws \Drenso\OidcBundle\Exception\OidcException
  #[Route('/login_oidc', name: 'login_oidc')]
  public function surfconext(OidcClientInterface $oidcClient): RedirectResponse
    // Redirect to authorization @ OIDC provider
    return $oidcClient->generateAuthorizationRedirect();

It is possible to supply prompt, scopes and additional query parameters to the generateAuthorizationRedirect method.

It is also possible to force remember me mode for the redirect.

That should be all!

User identifier

By default, this bundle uses the sub property as user identifier, but any property from the retrieved user data can be used. Just configure the user_identifier_property with an property path string compatible with the Symfony Property Accessor to retrieve the value you need.

Note that the object based access method is used to retrieve the properties from the user data.

Remember me

If you want to enable remember me functionality make sure that you add the _remember_me=1 query parameter to the route being used to generate the redirect forward (the one that calls generateAuthorizationRedirect).

You can override the _remember_me parameter per OIDC client. Just update the remember_me_parameter value in the client configuration.

Lastly, make sure the Symfony remember me authenticator is enabled, and that you set the enable_remember_me option to true for the oidc authenticator in security.yaml.

When a user is authenticated, you will see the REMEMBERME cookie. You can remove the PHPSESSID cookie to check whether remember me is working.


It is possible to enable "logout" through the end_session_support functionality of the Identity Provider, if the end_session_endpoint parameter is present in the .well-known endpoint it can be used.

As logging out is fundamentally broken when using single sign-on, this option is disabled by default. This is due to the fact that logging out at the identity provider (for example: Azure, Facebook, etc) cannot guarantee the user is logged out of any other service that the user has authenticated with using the same identity provider.

If you want to enable the "logout" support, simply add enable_end_session_listener: true to your oidc listener in the firewall config. It will only work of you enabled the default Symfony logout: true setting in your firewall.

By default, the listener will pass the logout target_path to the OpenID Provider, so the user gets redirected back to your application after logging out. If you don't want this and want the user to remain at the logout confirmation page of your OpenID Provider, enable the use_logout_target_path: false setting.

Example: default logout path

      logout: true
        enable_end_session_listener: true

Example: custom logout path

        target: /my_custom_target_path
        enable_end_session_listener: true

Example: disable redirect to logout target_path

This will keep the user at the OpenID provider after login out.

      logout: true
        enable_end_session_listener: true
        use_logout_target_path: false

Client locator

If for some reason you have several OIDC clients configured and need to retrieve them dynamically, you can use the OidcClientLocator.

  public function surfconext(OidcClientLocator $clientLocator): RedirectResponse
    return $clientLocator->getClient('your_client_id')->generateAuthorizationRedirect();

The locator will throw an OidcClientNotFoundException when the requested client is not found. When called without an argument, it will return the configured default client.


When you have symfony/cache available in your project, this library will automatically cache the well known data. By default, it will be cached for 3600 seconds.

You can disable this cache by passing null to the well_known_cache_time client option.

Refreshing tokens

Currently, the firewall implementation provided by this bundle does not offer refresh tokens (as it should not be necessary). However, if you need to refresh the tokens yourself for your implementation, you can use the refreshTokens method on the OidcClientInterface!

Parsing well-known information

Some providers return incorrect or incomplete well known information. You can configure a custom well-known parser for the OidcClient by setting the well_known_parser to a service id which implements the OidcWellKnownParserInterface.
