EtcpasswdOAuthBundle

This bundle is is still under development, things might change!

Installation

using svn:

$ git clone https://github.com/mazen/EtcpasswdOAuthBundle.git vendor/bundles/Etcpasswd/OAuthBundle
$ git clone https://github.com/kriswallsmith/Buzz.git vendor/buzz

register the namespaces in your autoloader:

# app/autoload.php
$loader->registerNamespaces(array(
    'Etcpasswd'        => __DIR__.'/../vendor/bundles',
    'Buzz'             => __DIR__.'/../vendor/buzz/lib',
    // .. your other namespaces
));

register the bundle within your Application's Kernel:

# app/AppKernel.php
$bundles = array(
    new Etcpasswd\OAuthBundle\EtcpasswdOAuthBundle(),
    // .. other bundles
);

Configure your security firewall:

# app/config/security.yml

firewalls:
    oauth:
      anonymous: true
      logout: true
      pattern: ^/
      oauth:
        auth_provider: api provider
        client_id:     client id
        client_secret: secret
        uid:           email
        scope:         requested scope
        login_path:    /login
        check_path:    /auth
        failure_path:  /

factories:
  - "%kernel.root_dir%/../vendor/bundles/Etcpasswd/OAuthBundle/Resources/config/security_factories.xml"

Please not that you do not need to build any controllers for either the login_path or the check_path. They are only used internally to identify when a login needs to happen.

Also note that you still have to provide a user provider. This bundle only authenticates the user based on an OAuth service but does not create any User object itself.

Specifying multiple OAuth2 Providers

This package also allows to use different providers at once for signing in. All you have to do is to add those providers to the security.yml

Example:

firewalls:
    main:
      anonymous: true
      logout: true
      pattern: ^/

      oauth_github:
        auth_provider: "github"
        client_id: xxx
        client_secret: xxx
        scope: repo,user
        login_path: /login/github
        check_path: /auth/github
        failure_path:  /

      oauth_facebook:
        auth_provider: "facebook"
        client_id:     xxx
        client_secret: xxx
        scope:         ""
        login_path:    /login/facebook
        check_path:    /auth/facebook
        failure_path:  /

      oauth_google:
        auth_provider: "google"
        client_id:     xxx
        client_secret: xxx
        scope:         "https://www.googleapis.com/auth/plus.me"
        login_path:    /login/google
        check_path:    /auth/google
        failure_path:  /

Calling either /login/github, /login/facebook or /login/google will then use the correct oauth provider.

Builtin OAuth Providers

This bundle ships with the following builtin providers:

• Github
• Facebook
• Google

Notes on Google: you need to at least provide the scope https://www.googleapis.com/auth/plus.me in order to get a username

Authorizing users

This bundle does not ship with any way of authorization of users and / or persitant state. You should have a look at the https://github.com/FriendsOfSymfony/FOSUserBundle for that. If you want to use those users anyways, without ever wanting to persist them into a database, you can though add the provider shipped with this bundle to your security configuration. This will allow you to access the accessToken via the Security Context service to query other API services from the given provider.

Example security.yml:

security:
  firewalls:
    main:
      anonymous: true
      logout: true
      pattern: ^/

      oauth_github:
        auth_provider: "github"
        client_id:     xxx
        client_secret: xxx
        scope: repo,user
        login_path: /login/github
        check_path: /auth/github
        failure_path:  /

  role_hierarchy:
    ROLE_ADMIN: [ROLE_USER]

  providers:
    main:
      id: etcpasswd_oauth.user.provider
  
  access_control: ~  

  factories:
    - "%kernel.root_dir%/../vendor/bundles/Etcpasswd/OAuthBundle/Resources/config/security_factories.xml"
