Hello,

At this time I can export/import all main calendars kronolith to davical but it seems there is an issue about permission. In fact each of all ics files ì get has a SUMMARY:busy... 
I found it is due to kronolith/lib/Event.php getTitle method in which it seems the current user has not permissions.
[CODE]
// We explicitly allow admin access here for the alarms notifications.
        if (!$GLOBALS['registry']->isAdmin() && $this->private && $this->creator != $user) {
              return _("busy");
             } elseif ($GLOBALS['registry']->isAdmin() || $this->hasPermission(Horde_Perms::READ, $user)) {
                   return strlen($this->title) ? $this->title : _("[Unnamed event]");
             }  else {
                        return _("busy");
             }
[/CODE]

Could you please indicate me  how to set up the permissions in my script :

[CODE]
#!/usr/bin/env php
<?php
set_include_path('/www/horde4/pear/php' . PATH_SEPARATOR . get_include_path());
if (file_exists(dirname(__FILE__) . '/../../kronolith/lib/Application.php')) {
    $baseDir = dirname(__FILE__) . '/../';
} else {
    require_once 'PEAR/Config.php';
    $baseDir = PEAR_Config::singleton()
        ->get('horde_dir', null, 'pear.horde.org') . '/kronolith/';
}

require_once dirname(__FILE__) . '/../lib/Application.php';
Horde_Registry::appInit('kronolith', array(
    'cli' => true
));
// Call a Registry method.
// Retrieve a list of users associated with each calendar, and
    // thus a list of users who have used kronolith and
    // potentially have an agenda preference set.
    $calendars = $GLOBALS['kronolith_shares']->listAllShares();
    $users = array();
    foreach (array_keys($calendars) as $calendarId) {
        try {
            $calendar = $GLOBALS['kronolith_shares']->getShare($calendarId);
        } catch (Exception $e) {
            die($e->getMessage());
        }
        $users = array_merge($users, $calendar->listUsers(Horde_Perms::READ));
    }
 // Remove duplicates.
    $users = array_unique($users);
natcasesort($users);
// Tell the registry that we are doing authentication ourselves.
define('AUTH_HANDLER', true);
$contentType = 'text/calendar';
foreach ($users as $user) {
   $registry->setAuth($user, array('password' => ''));
   $cals[$user] = $registry->call('calendar/listCalendars', array(true, HORDE_PERMS::READ));
   if ($cals[$user]['0'] != '') {
      if (strpbrk($user, '*') != true) {
       if ($user != 'mmiville')  {
           $export[$user] = $registry->call('calendar/exportCalendar', array($cals[$user]['0'], $contentType, Horde_Perms::READ));
           $file = '/home/webadm/exported_calendars/' . $user . '.ics';
           $hdl = fopen ($file, a);
           fwrite($hdl,($export[$user]));

}
}
} //end of foreach
fclose($hdl);
[/CODE]

Any help would be appreciated.

Best regards.
