$userManager = \OC::$server->getUserManager(); $user = $userManager->createUser('username', 'password');
$authBackend = new \OCA\user_ldap\lib\Backend\Ldap(); $authBackend->setConfiguration($ldapConfiguration); $userSession = new \OC\User\Session($authBackend); $userSession->login('username', 'password');This code authenticates a user using LDAP as the authentication backend. The OC_User class provides an abstraction layer to different authentication backends, and in this case, it is using the ownCloud LDAP backend provided by the user_ldap package library. In conclusion, OC_User is a class in the ownCloud package library that provides functionality to manage and authenticate users in an ownCloud instance. It provides methods to create, update and delete users, as well as authenticate them using different authentication backends. The examples provided above show how to use this class to create new users and authenticate them using LDAP.
