Carnegie Learning LdapOrm

A Symfony bundle that provides ORM over LDAP.

This code is based upon Ucsf Ldap Orm which in turn is based on Mathieu Goulin's GorgLdapOrmBundle.

We are forever indebted to them for providing an excellent base for the work we've continued at Carnegie Learning. Originally we forked UcsfLdapOrm, however we found many improvements and wanted to give back to the community.

What's changed and/or been added so far:

• Added the LdapEntity class. This is a Symfony entity which represents the top LDAP object class.
• Added many subclasses of LdapEntity to describe the object classes from top down to InetOrgPerson.
• Added Repository::filterByComplex() which gives the entity manager/repository the ability to filter with custom constructed, complex boolean logic. (See code comment API documentation for details.)
• Removed the dependency upon TWIG at all.

Installation

Requires PHP5.5+ and Symphony 2.8+

• Add with composer
  • composer require carnegielearning/ldap-orm-bundle
• Add the bundle to AppKernel.php
  • new CarnegieLearning\LdapOrmBundle\CarnegieLearningLdapOrmBundle()
• Install using composer
  • $ composer update carnegielearning/ldap-orm-bundle

Testing Requirements

It is suggested that you run the unit tests using grunt. This will allow for an in memory ldap server to be stood up in place and facilitate file watching as well.

• Install Node.js and npm
• Install Grunt into the global namespace. Refer to the grunt documentation for help.
• Run the installation for npm.
• Be sure that a java binary exists within the development environment. Please refer to the ldap sdk form more information.
• Run grunt. This will run a file watcher that watches for changes in the source folders/files as well as test folders/files. To exit be sure to use ctrl-c as this will kill the in-memory-ldap server
• It is possible to also run just the unit tests with out the file watcher portion. This can be accomplished with

Documentation

Develop with LdapOrm

Configure an LDAP service in config.yml

• uri: The URI you need for connecting to the LDAP service.
• __use_tls__: 'true' or 'false' to decide on connecting with TLS
• __bind_dn__: The DN for binding to the LDAP service
• password: The password associated with the given bind DN
• __password_type__: sha1 or plaintext. I use plaintext when the URI is LDAPS.

Dependency injection for LDAP Entity Managers and Services

Creating Entities (usually to represent an object class)

class ComExamplePersonService {

protected $comExamplePersonRepository;

public function __construct(LdapEntityManager $entityManager) {
    // Make a repo for ComExamplePerson entities
    $this->comExamplePersonRepository = $entityManager->getRepository(ComExamplePerson::class);
    // Make a another repo for SomethignElse entities (just another example...)
    $this->somethingElseRepository = $entityManager->getRepository(SomethingElse::class);
    ...
}

public function getPersonByUid($uid, $includeAddress = false, $attributes = null) {
    $person = $this->comExampePersonRepository->findByUid($uid, $attributes);
    ...
    return $person;
}

` class PeopleController extends Controller {

    /**
     * @Route("/person/detail/{uid}")
     * @Template()
     */
    public function detailAction(Request $request, $uid)
    {
        $comExamplePersonService = $this->get('comexample_person_service');
        $person = $comExamplePersonService->getPersonByUid($uid);
        ...
        return array('person' => $person);
    }

## To do

1. ~~Remove need for generic LDAP config~~
2. ~~Configuration documentation~~
3. ~~Development example~~
4. Rewrite test suite (In progress...)
5. Remove deprecated search results iterator
