<?php
/**
* This is where all authentication providers register themselves as
* available to the system. Only the classes are registered here, not
* specific instances.
*
* For instance, an LDAP authentication provider is registered. It
* can't, by itself, perform any authentication, as it is not
* configured.
*
* The authenticators table in the database lists specific instances
* configured in the system. It contains it's own name (for humans to
* differentiate between instances), it's own namespace name (for the
* system and plugins to be able to find it accurately), it's
* authentication provider namespace name, and some configuration data
* that is handed over to the authentication provider instance to
* configure itself.
*
* If a user has no authenticator set up, the KnowledgeTree
* Authentication Provider is used. This is hard-coded to use the
* KnowledgeTree users table to check the password against.
