This callback triggered before the actual action code is executed. This is useful to do checks before actual action executed. One of the example is captcha :)

<?php
function my_component_init(){
ossn_register_callback('action', 'load', 'my_component_cb');
}
function my_component_cb($callback, $type, $params){
//$params['action'] contains the action name
if($params['action'] == 'user/login'){
//do some stuff......
}
}
ossn_register_callback('ossn', 'init', 'my_component_init');
