Integrating SAML

Hello, I am trying to integrate SAML with my CI app using config/autoload.php.

Below is the library I need throughout my CI app

PHP Code:

$path = '/usr/share/simplesamlphp/lib';
set_include_path(get_include_path() . PATH_SEPARATOR . $path);
require_once('_autoload.php'); 


I tried to insert the above code into config/autoload.php under "Auto-load packages" like this (I am not even sure if this is how I'm supposed to do it)

PHP Code:

$path = '/usr/share/simplesamlphp/lib';
set_include_path(get_include_path() . PATH_SEPARATOR . $path);

$autoload['packages'] = array($path.'_autoload', '/usr/share/simplesamlphp/lib'); 


However, it is not working. Can anybody help me in trying to autoload SAML? I'd appreciate any help here.
