[Plugin: simpleSAMLphp Authentication] Network update for simpleSAMLphp plugin
-
I found this plugin to work well but it only adds the user connecting to one blog. I have updated the plugin so that when connecting to a WordPress Network it will add the user and then provision a new blog using the username as the identifier.
I’ve quickly removed some of the paths from my own install but the code I uses is as follows. Thought it might help with version 0.6 ??
register_activation_hook( __FILE__, 'set_simplesamlphp_settings' ); add_action('admin_menu', 'simplesaml_authentication_add_options_page'); $simplesaml_authentication_opt = get_site_option('simplesaml_authentication_options'); $simplesaml_configured = true; // try to configure the simpleSAMLphp client if ($simplesaml_authentication_opt['include_path'] == '') { $simplesaml_configured = false; } else { $include_file = $simplesaml_authentication_opt['include_path']."/lib/_autoload.php"; if (!include_once($include_file)) $simplesaml_configured = false; } if ($simplesaml_configured) { if($simplesaml_authentication_opt['sp_auth'] == '') $sp_auth = 'default-sp'; else $sp_auth = $simplesaml_authentication_opt['sp_auth']; $as = new SimpleSAML_Auth_Simple($sp_auth); } // for wp_create_user function on line 120 require_once (ABSPATH .
