[turba] Global address book - user permisssions

[/dustbin]

hello,

 i have configured horde and imp which is working fantastic and now want to
turba. I created two tables in mysql (horde DB), 1)turba_objects for storing
users personal address book n
 2)ga_book for storing the Global Address Book. this is my
turba/sources.php..

$cfgSources['localsql'] = array(
    'title' => _("My Personal Address Book"),
    'type' => 'sql',
    // The default connection details are pulled from the Horde-wide SQL
    // connection configuration.
    //
    // The old example illustrates how to use an alternate database
    // configuration.
    //
    // New Example:
    'params' => array_merge($conf['sql'], array('table' =>
'turba_objects')),

    // Old Example:
     'params' => array(
         'phptype' => 'mysql',
         'hostspec' => 'localhost',
         'username' => 'horde',
         'password' => 'xxxxxxxxx',
         'database' => 'horde',
         'table' => 'turba_objects',
         'charset' => 'iso-8859-1'
     ),
    'map' => array(
        '__key' => 'object_id',
        '__owner' => 'owner_id',
        '__type' => 'object_type',

    'browse' => true,
    //'use_shares' => true,
    'public' => false,
    'readonly' => false,
     //'export' => true

);
$cfgSources['gadd'] = array(
    'title' => _("Global (Company) Addressbook"),
    'type' => 'sql',
    // The default connection details are pulled from the Horde-wide
