Check out Dovecot log, probably enable auth_debug and, maybe
auth_debug_passwords, too.
Is your Horde login password the same as your Dovecot password?
Do you use IMP as Horde authentification service?

My local backends file contains:

<?PHP

$backends['imap']['disabled'] = true;
$backends['sieve']['disabled'] = false;
$backends['sieve']['transport'][Ingo::RULE_ALL]['params']['usetls'] = false;
$backends['sieve']['transport'][Ingo::RULE_ALL]['params']['scriptname'] = 'horde5-ingo';
$backends['sieve']['script'][Ingo::RULE_ALL]['params']['utf8'] = true;
