| /** |
| * Storage driver for fetching login data from SOAP |
| * |
| * This class takes one parameter (options), where |
| * you specify the following fields: endpoint, namespace, |
| * method, encoding, usernamefield and passwordfield. |
| * |
| * You can use specify features of your SOAP service |
| * by providing its parameters in an associative manner by |
| * using the '_features' array through the options parameter. |
| * |
| * The 'matchpassword' option should be set to false if your |
| * webservice doesn't return (username,password) pairs, but |
| * instead returns error when the login is invalid. |
| * |
| * Example usage: |
| * |
| * <?php |
| * |
| * ... |
| * |
| * $options = array ( |
| * 'endpoint' => 'http://your.soap.service/endpoint', |
| * 'namespace' => 'urn:/Your/Namespace', |
| * 'method' => 'get', |
| * 'encoding' => 'UTF-8', |
| * 'usernamefield' => 'login', |
| * 'passwordfield' => 'password', |
| * 'matchpasswords' => false, |
| * '_features' => array ( |
| * 'example_feature' => 'example_value', |
| * 'another_example' => '' |
| * ) |
| * ); |
| * $auth = new Auth('SOAP', $options, 'loginFunction'); |
| * $auth->start(); |
| * |
| * ... |
