README
LdapBundle provides LDAP authentication without using Apache's mod_ldap
. The bundle instead relies on PHP's LDAP extension along with a form to authenticate users. LdapBundle can also be used for authorization by retrieving the user's roles defined in LDAP.

Get the Bundle
Composer
Add LdapBundle in your project's 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
Note:
An example
security.yml
file is located within the bundle at./Resources/Docs/security.yml
# ./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 # network_timeout: 10 # Optional # referrals_enabled: true # Optional # bind_username_before: true # Optional # skip_roles: false # 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 ] # user_class: IMAG\LdapBundle\User\LdapUser # Optional
You should configure the parameters under the imag_ldap
section to match your environment.
Note:
The optional parameters have default values if not set. You can disable default values by setting a parameter to NULL.
# app/config/security.yml imag_ldap: # ... role: # ... filter: NULL
Import routing
# app/config/routing.yml imag_ldap: resource: "@IMAGLdapBundle/Resources/config/routing.yml"
Implement Logout
Just create a link with a logout target.
<a href="{{ path('logout') }}">Logout</a>
Note:
You can refer to the official Symfony documentation : http://symfony.com/doc/current/book/security.html#logging-out
Chain provider
You can also chain the login form with other providers, such as database_provider, in_memory provider, etc.
# app/config/security.yml security: firewalls: secured_area: pattern: ^/ anonymous: ~ imag_ldap: provider: multiples logout: path: logout providers: multiples: chain: providers: [ldap, db] ldap: id: imag_ldap.security.user.provider db: entity: { class: FQDN\User }
Note:
If you have set the config option
bind_username_before: true
you must chain the providers with the ldap provider in the last position.
# app/config/security.yml providers: [db, ldap]
Subscribe to PRE_BIND event
The PRE_BIND is fired before the user is authenticated via LDAP. Here you can write a listener to perform your own logic before the user is bound/authenticated to LDAP. For example, to add your own roles or do other authentication/authorization checks with your application.
If you want to break the authentication process within your listener, throw an Exception.
Example listener:
<service id="ldap.listener" class="Acme\HelloBundle\EventListener\LdapSecuritySubscriber"> <tag name="kernel.event_subscriber" /> </service>
Example:
<?php namespace Acme\HelloBundle\EventListener; use Symfony\Component\EventDispatcher\EventSubscriberInterface; use IMAG\LdapBundle\Event\LdapUserEvent; /** * Performs logic before the user is found to LDAP */ class LdapSecuritySubscriber implements EventSubscriberInterface { public static function getSubscribedEvents() { return array( \IMAG\LdapBundle\Event\LdapEvents::PRE_BIND => 'onPreBind', ); } /** * Modifies the User before binding data from LDAP * * @param \IMAG\LdapBundle\Event\LdapUserEvent $event */ 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(sprintf('LDAP user %s not allowed', $user->getUsername())); } $user->addRole('ROLE_LDAP'); $event->setUser($user); } }
Subscribe to POST_BIND event
The POST_BIND is fired after the user is authenticated via LDAP. You can use it in exactly the same manner as PRE_BIND.
Note:
However each time a page is refreshed, Symfony call the refreshUser method in the provider that is used and doesn't trigger these events (PRE_BIND and POST_BIND). If you want to override user (for example like credentials, roles ...), you must create a new provider and override this method.
