README

LdapBundle provides a Ldap authentication system without the apache mod_ldap. It uses php-ldap extension with a form to authenticate the users. LdapBundle also can be used for the authorization. It retrieves the Ldap users' roles.

Get the Bundle

Composer

Modify your composer.json on your project root

// {root}/composer.json

{
    [...],
    "require": {
        [...],
        "imag/ldap-bundle": "dev-master"
    }
}

Enable the Bundle

<?php
// app/AppKernel.php

public function registerBundles()
{
    $bundles = array(
    // ...
    new IMAG\LdapBundle\IMAGLdapBundle(),
    );
}

Configure security.yml

# src/IMAG/LdapBundle/Resources/config/security.yml

security:
  firewalls:
    restricted_area:
      pattern:          ^/
      anonymous:        ~
      provider:         ldap
      imag_ldap:        ~
      # alternative configuration
      # imag_ldap:
      #   login_path:   /ninja/login
      logout:
        path:           /logout
        target:         /

  providers:
    ldap:
      id: imag_ldap.security.user.provider
                
  encoders:
    IMAG\LdapBundle\User\LdapUser: plaintext

  access_control:
    - { path: ^/login,          roles: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/,               roles: IS_AUTHENTICATED_FULLY }

imag_ldap:
  client:
    host: your.host.foo
    port: 389
#    version: 3 # Optional
#    username: foo # Optional
#    password: bar # Optional

  user:
    base_dn: ou=people,dc=host,dc=foo
#    filter: (&(foo=bar)(ObjectClass=Person)) #Optional
    name_attribute: uid
  role:
    base_dn: ou=group, dc=host, dc=foo
#    filter: (ou=group) #Optional
    name_attribute: cn
    user_attribute: member
    user_id: [ dn or username ]

You need to configure the parameters under the imag_ldap section.

Note:

If are not set, the optional parameters have default values. You can disable this ; Just set parameter to NULL.

imag_ldap:
  # ...
  role:
   # ...
   filter: NULL

Import security.yml

# app/config/config.yml

imports:
  - { resource: ../../src/IMAG/LdapBundle/Resources/config/security.yml }

Import routing

# app/config/routing.yml

imag_ldap:
  resource: "@IMAGLdapBundle/Resources/config/routing.yml"

Implement Logout

Just create a link with logout target.

<a href="{{ path('logout') }}">logout</a>

Note: You can refer to the official Symfony documentation : http://symfony.com/doc/2.0/book/security.html#logging-out

Subscribe to PRE_BIND event

Now you can perform you own logic before the user is authenticated on Ldap. If you want to break the authentication just return an Exception.

To subscribe:

<tag name="kernel.event_listener" event="imag_ldap.security.authentication.pre_bind" method="onPreBind" />

Exemple:

<?php
use IMAG\LdapBundle\Event\LdapUserEvent,

public function onPreBind(LdapUserEvent $event)
{
    $user = $event->getUser();
    $config = $this->appContext->getConfig();

    $ldapConf = $config['ldap'];

    if (!in_array($user->getUsername(), $ldapConf['allowed'])) {
        throw new \Exception('Not allowed ldap user');
    }

    $user->addRole('ROLE_LDAP');
}
