baseurlpath not handled correctly by Drupal module

[GoogleCodeExporter]

1. Configure drupalauth + drupalauth4ssp
2. In simplesaml config.php file, set up baseurlpath to any valid URL 
(http://...)

Logins do not work, because the cookie path that drupal module is trying to set 
will equal to /http://... as per following code:

  // get the baseurlpath
  $config['baseurlpath'] = '/' . $sspConfig->getValue('baseurlpath');
