        $auth = $this->_obj->config->item('DB_auth');
        $this->_trinity['auth'] = $this->_obj->load->database($auth, TRUE);
        $sha_password = sha1(strtoupper($password));
        $query = $this->_trinity['auth']->select('username, sha_pass_hash')->from('account')->where('username', $username)->where('sha_pass_hash', $sha_password)->get();
        if($query->num_rows() > 0)
        {
            $data = array(
                'username'      => $username,
                'password'      => $password,
                'logged_in'     => TRUE,
                'ip_address'    => $_SERVER['REMOTE_ADDR']
