If you want to setup MIMP in parallel with IMP, you need the composite authentication driver with a browser switch.
To use the composite driver select it from the dropdown list in the authentication tab of the configuration interface or change $conf['auth']['driver'] to 'composite' in horde/config/conf.php.
In horde/config/conf.php, insert the following code:
(Note: the 'horde_sql' is for administrative tasks such as user manipulation as defined in 'admin_driver'. If you use other authentication mechanisms, please change the 'horde_sql' entry appropriately.)
$conf['auth']['params']['drivers'] = array( 'imp' => array('driver' => 'application', 'params' => array('app' => 'imp')), 'mimp' => array('driver' => 'application', 'params' => array('app' => 'mimp')), 'horde_sql' => array('driver' => 'sql', 'params' => array( 'hostspec' => 'localhost', 'phptype' => 'mysql', 'protocol' => 'unix', 'username' => 'horde', 'password' => 'hordepass', 'database' => 'horde'))); $conf['auth']['params']['admin_driver'] = 'horde_sql'; $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.
