Authentication API

Moodle authentication interface

Authentication API This file describes Moodle interface functions to authentication modules. (This page is incomplete , I'll update it after I have phpdoc commented auth/ldap/lib.php)

Most of functions are from ldap-authentication module and are not implemented (yet?) on other modules. Please feel free to extend other modules to support same features or roll your own module.

Some of new function are still tested and are not documented here yet.
