If you want to setup MIMP in parallel with IMP, you need the composite authentication driver with a browser switch.
In horde/config/conf.php, insert the following code:
$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.
