ShibbolethBundle

This is a Shibboleth bundle for Symfony 3+ that uses the Guard system.

Installation

Install bundle via composer by running the following command :

composer require unicesil/shibboleth-bundle

If you don't use flex, enable the bundle in config/bundles.php :

<?php

return [
    //...
    UniceSIL\ShibbolethBundle\UniceSILShibbolethBundle::class => ['all' => true]
];

Modify the file config/packages/unice_sil_shibboleth.yaml to add your shibboleth settings :

unice_sil_shibboleth:
    login_path: 'Shibboleth.sso/Login'  # The path used to call Shibboleth login authentication (default = 'Shibboleth.sso/Login')
    logout_path: 'Shibboleth.sso/Logout'  # The path used to call Shibboleth logout (default = 'Shibboleth.sso/Logout')  
    username: 'eppn'  # The Shibboleth attribute that is used as username for the logged in user. The attribute must appear in the'attributes' parameter list (default = 'username')
    attributes: ['eppn', 'mail', 'givenName', 'sn']  # The list of attributes returned by Shibboleth Service Provider
    login_target : ''  # The route to which the user will be redirected after login. If this parameter is not filled, the user will be redirected to the page from which he comes. (default = null)
    logout_target : ''  # The route to which the user will be redirected after logout. If this parameter is not filled, the user will be redirected to the page from which he comes. (default = null)

And modify your security.yml file to secure your application :

security:
    enable_authenticator_manager: true
    
    provider:
      shibboleth:
        id: Your\Shibboleth\User\Provider\Class
    
    firewalls:
        dev:
            pattern: ^/(_(profiler|wdt)|css|images|js)/
            security: false
        shibboleth:
            lazy: true
            provider: shibboleth
            custom_authenticators:
              - unicesil.shibboleth_authenticator
            logout: ~

    access_control:
        - { path: ^/, roles: ROLE_USER }

Configure your application .htaccess or your apache configuration:

AuthType shibboleth
ShibRequestSetting requireSession 0
ShibUseHeaders On
ShibRequestSetting applicationId engagement
Require shibboleth

User and UserProvider

Create your own User and UserProvider classes

User

class User extends UserInterface
{
    //...

    public function getUserIdentifier() {
        // ...
    }
    
}

UserProvider

use UniceSIL\ShibbolethBundle\Security\Provider\AbstractShibbolethUserProvider;

class MyShibbolethUserProvider extends AbstractShibbolethUserProvider
{
    public function loadUserByIdentifier(string $identifier): UserInterface
    {
        $shibbolethUserAttributes = $this->getAttributes();
        
        // Return an instance of User
    }
}

Logout

to properly disconnect your users from the application via Shibboleth, configure the listener as follows in the service.yaml file.

unicesil.shibboleth_logout_event:
    class: UniceSIL\ShibbolethBundle\EventListener\LogoutEventListener
    arguments: ['%unice_sil_shibboleth%', "@router"]
    tags:
        - name: 'kernel.event_listener'
          event: 'Symfony\Component\Security\Http\Event\LogoutEvent'
          method: onLogout
          dispatcher: security.event_dispatcher.{YOUR_FIREWALL_NAME} # ex: security.event_dispatcher.main

Configure the logout route in security.yaml.

security:
    firewalls:
        shibboleth:
            logout:
              path: /logout

Don't forgot to declare the logout route in your route configuration file.

logout:
    path: /logout
