[gollem] File backend issue

[binaerklo at arcor.de]

Dear List,

I seem to not get the point on how I can segregate users within gollem on a file-driver backend. 
EVERY user CAN go beyond his root and back up again to shares of others. I want these to be jailed but
have a dedicated user for overall browsing, how can I acomplish that ?

Here's the relevant part of my backends.local.php:

  // The base location under which the user home directories live.
        'vfsroot' => '/usr/local/www/repository/external',
     // The default permissions to set for newly created folders and files.
        // 'permissions' => 0750
    ),
    'loginparams' => array(),
    'root' => '/',
    'home' => $GLOBALS['registry']->getAuth(),
    // 'createhome' => false,
    // 'filter' => '^regex$',
    // 'quota' => false,
