If you want to setup MIMP in parallel with IMP, you need the [AuthCompositeHowTo composite authentication driver] with a browser switch:
$conf['auth']['params']['drivers'] = array(
'imp' => array('driver' => 'application',
'params' => array('app' => 'imp')),
'mimp' => array('driver' => 'application',
'params' => array('app' => 'mimp')));
$conf['auth']['params']['loginscreen_switch'] = '_horde_select_loginscreen';
if (!function_exists('_horde_select_loginscreen')) {
function _horde_select_loginscreen()
{
require_once 'Horde/Browser.php';
$browser = &new Browser();
if ($browser->isMobile()) {
return 'mimp';
}
return 'imp';
}
}
This will give you either the IMP or the MIMP login screen, depending on the browser you use.
