I use the following in horde/config/hooks.php:

if (!function_exists('_imp_hook_vinfo')) {
         function _imp_hook_vinfo($type = 'username') {
                 if ($type == 'username') {
                         return preg_replace('/\s/', '', strtolower($_SESSION['imp']['user']));
                 } elseif ($type == 'vdomain') {
                         return '';
                 } else {
                         return PEAR::raiseError('invalid type: ' . $type);
                 }
         }
}


Then I set the following in imp/config/conf.php:

$conf['hooks']['vinfo'] = true;


This hook will lowercase the username entered in the login form before it 
used in Horde/IMP.

We run Cyrus here with saslauthd.  saslauthd is configured to use PAM, and 
we use both pam_unix and pam_ldap together.
