Fix your configuration. You should *never* modify  
'horde/imp/config/backends.php', only override defaults in  
'horde/imp/config/backends.local.php' like

<?php
$servers['imap']['name'] = 'GMail IMAP Server';
$servers['imap']['hostspec'] = 'imap.gmail.com';
$servers['imap']['hordeauth'] = true;
$servers['imap']['port'] = 993;
$servers['imap']['secure'] = 'ssl';

Then enable debugging

$servers['imap']['debug'] = '/tmp/imp_imap.log';

The information in the logfile should provide clues why Gmail won't  
let you in.
