SimplesamlphpBundle

This is a SimpleSAMLphp Bundle for Symfony2.

Note: For Symfony 2.7 or lower, you need to use the 1.0.0 release of this bundle.

Installation

Add this bundle to your Symfony2 project.

composer require hslavich/simplesamlphp-bundle

or manually require this bundle in your composer.json file.

"require": {
    ...
    "hslavich/simplesamlphp-bundle": "dev-master"
}

Update your project.

composer update hslavich/simplesamlphp-bundle

Activate the bundle in app/AppKernel.php.

$bundles = array(
    ...
    new Hslavich\SimplesamlphpBundle\HslavichSimplesamlphpBundle(),
)

Configuration

Add bundle configuration settings to your Symfony2 config.

# app/config/config.yml
hslavich_simplesamlphp:
    # Service provider name
    sp: default-sp

You will need to create your own user provider. See the Symfony2 documentation "How to Create a custom User Provider".

1. First, create a User class (you can also place it in your Entity/ folder)

    # src/Acme/MyBundle/Security/User/MyUser.php
    namespace Acme\MyBundle\Security\User;
   
    use Symfony\Component\Security\Core\User\UserInterface;
    use Symfony\Component\Security\Core\User\EquatableInterface;
   
    class MyUser implements UserInterface, EquatableInterface
    {
        ...
    }
   

2. Then create the UserProvider class

    # src/Acme/MyBundle/Security/User/MyUserProvider.php
    namespace Acme\MyBundle\Security\User;
   
    use Symfony\Component\Security\Core\User\UserProviderInterface;
    use Symfony\Component\Security\Core\User\UserInterface;
    use Symfony\Component\Security\Core\Exception\UsernameNotFoundException;
    use Symfony\Component\Security\Core\Exception\UnsupportedUserException;
   
    class MyUserProvider implements UserProviderInterface
    {
        public function loadUserByUsername($username) { ... }
        public function refreshUser(UserInterface $user) { ... }
        public function supportsClass($class) { ... }
    }
   

3. And make your UserProvider a service

    # src/Acme/MyBundle/Resources/config/services.yml
    services:
        my_user_provider:
            class: Acme\MyBundle\Security\User\MyUserProvider
   

Then add the provider and firewalls settings to you Symfony2 security file.

# app/config/security.yml
security:
    providers:
        simplesaml:
            id: my_user_provider

    firewalls:
        saml:
            pattern:    ^/
            anonymous: true
            stateless:  true
            simple_preauth:
                authenticator: simplesamlphp.authenticator
                provider: simplesaml
            logout:
                path:   /logout
                success_handler: simplesamlphp.logout_handler

Create the following file structure in your app/ folder and place your configuration files in there.

app/
  config/
    simplesamlphp/
      cert/
        saml.crt
        saml.pem
      config/
        config.php
        authsources.php
      metadata/
        saml20-idp-remote.php # Example

Make sure to correctly set the paths for cert/ and metadata/ folders in your config.php file (absolute paths recommended). The metadata/saml20-idp-remote.php is just an example. See the SimpleSAMLphp documentation, "Adding IdPs to the SP" for more information.

You may also place those folders anywhere else on your machine, just make sure to correctly set the SIMPLESAMLPHP_CONFIG_DIR environment variable (see below).

Add the environment variable to your webserver configuration file, e.g. /etc/apache2/httpd.conf.local.

<Directory *>
    ...
    SetEnv SIMPLESAMLPHP_CONFIG_DIR /var/path/to/my/config
</Directory>

Enable session bridge storage (see Symfony documentation for more information).

# app/config/config.yml
framework:
    session:
        storage_id: session.storage.php_bridge
        handler_id: ~

Create an alias on your webserver, e.g. for an Apache2 webserver, add this line to you http.conf.local (or other desired configuration file).

Alias /simplesaml /home/myapp/vendor/simplesamlphp/simplesamlphp/www
