appserver.io LDAP

This is a basic LDAP integration that provides a Doctrine ORM like functionality for LDAP handling.

Data Source

To define a Data Source, simply add a XML file with a following structure to your application's META-INF directory

<?xml version="1.0" encoding="UTF-8"?>
<datasources xmlns="http://www.appserver.io/appserver">
    <datasource name="my-ldap-ds">
        <database>
            <driver>ext_ldap</driver>
            <user>cn=admin,dc=example,dc=org</user>
            <password>admin</password>
            <databaseName>dc=example,dc=org</databaseName>
            <databaseHost>127.0.0.1</databaseHost>
            <databasePort>389</databasePort>
        </database>
    </datasource>
</datasources>

Persistence Manager

Configure the Persistence Manager in META-INF/persistence.xml like

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://www.appserver.io/appserver">
    <persistenceUnits>
        <persistenceUnit
            name="MyLdapEntityManager"
            interface="AppserverIo\Appserver\Ldap\EntityManagerInterface"
            type="AppserverIo\Appserver\Ldap\EntityManager"
            factory="AppserverIo\Appserver\Ldap\EntityManagerFactory">
            <datasource name="my-ldap-ds"/>
        </persistenceUnit>
    </persistenceUnits>
</persistence>

Inject the Persistence Manager

The LDAP Persistence Manager can then be injected as a Doctrine Entity Manager, e. g.

/**
 * TechDivision\Project\Repositories\Ldap\RoleRepositoryInterface
 */

namespace AppserverIo\MyProject;

/**
 * Dummy implementation of a LDAP repository.
 */
class DummyRepository
{

    /**
     * The Symfony LDAP adapter instance.
     *
     * @var \AppserverIo\Appserver\PersistenceContainer\Doctrine\DoctrineEntityManagerProxy
     * @EPB\PersistenceUnit(unitName="MyLdapEntityManager")
     */
    protected $ldapEntityManager;
}

Persistence Manager Interface

The LDAP Persistence Manager provides the following interface which gives you access to your LDAP.

ATTENTION: In version 2.x persist() and remove() methods has not yet been implemented.
