If this is the code in oauth2_servers.services_auth.inc
module, what is the url to enable the "require authentication" checkbox?
/**
* Services authentication "controller_settings" callback.
*/
function oauth2_server_services_controller_settings($settings, $controller, $endpoint, $class, $name) {
$form = array();
$form['require_authentication'] = array(
'#type' => 'checkbox',
'#title' => t('Require authentication'),
'#default_value' => isset($settings['require_authentication']) ? $settings['require_authentication'] : FALSE,
);
$form['scope'] = array(
'#type' => 'textfield',
'#title' => t('Scope'),
'#default_value' => isset($settings['scope']) ? $settings['scope'] : '',
'#description' => t('A space-separated list of required scopes. Leave empty to ignore the check.'),
);
return $form;
