Is it possible to login to module from out side the module as shown as below?
ie:
$authStaff =array('username'=>'staff','password'=>'admin');
$identitystaff = new StaffIdentity($authStaff['username'],$authStaff['password']);
if($identitystaff->authenticate())
{
Yii::app()->getModule('staff')->user->login($identitystaff);
}
