This works:

```
return [
    'zf-mvc-auth' => [
        'authentication' => [
            'map' => [
                'Admin\\MyModule\\Controller' => 'session',
            ],

```

but it is applicable to all controllers. It means that cannot be controller without adapter.  
But this doesn’t:

```
return [
    'zf-mvc-auth' => [
        'authentication' => [
            'map' => [
                'Admin\\MyModule\\Controller\\UserController' => 'session',
            ],

```

because of this line [https://github.com/zfcampus/zf-mvc-auth/blob/master/src/Authentication/DefaultAuthenticationListener.php#L233](https://github.com/zfcampus/zf-mvc-auth/blob/master/src/Authentication/DefaultAuthenticationListener.php#L233) where script added double backslashes to the $api variable which will not matches with $controller name.

‘Admin\MyModule\Controller\UserController\’ - this will be assign to the $api variable;  
‘Admin\MyModule\Controller\UserController’ - this will be assign to the $controller variable. How to get around of this?
