[TYPO3-mvc] Backend modules not in access list

[roberto blanko]

Hello list,

I've added a backend module to the user section of the menu like this:

    Tx_Extbase_Utility_Extension::registerModule(
        $_EXTKEY,
        'user',                    // Make module a submodule of 'web'
        'tx_myext',    // Submodule key
        'before',                        // Position
        array(                          // An array holding the
controller-action-combinations that are accessible
            'MyController' => 'index',
        ),
        array(
            'access' => 'user,group',
            'icon'   => 'EXT:wes_myext/ext_icon.gif',
            'labels' => 'LLL:EXT:' . $_EXTKEY .
'/Resources/Private/Language/locallang_mod.xml',
        )
    );

This works fine, but the module does not appear in the acces list of be user
groups. So it is always visible for every backend user. How can I configure
which user group / user is allowed to use/see the module?

Regards
