[horde] using cyrus.php driver with ldap

[Mark]

I'm trying to setup Horde using cyrus for a driver
(lib/Auth/cyrus.php).
Not sure what I'm doing wrong. I can log in fine, but administration
part is not quite working. For example, when I log in as administrator
and click on Administration -> Users, I get:

Auth_cyrus: Backend does not have required capabilites.

I've sniffed the traffic, and no packet even leaves the box (ldap is on
another box, and cyrus imapd is on another), then I looked at the
source a little and decided to seek help :). It looks like some error
in my config, but not sure what. Google gives nothing, only few
examples on using sql, and pretty much nothing on ldap. Here is my Auth
section from horde/config/conf.php:

$conf['auth']['driver'] = 'composite';
$conf['auth']['params']['loginscreen_switch'] =
'_horde_select_loginscreen';

$conf['auth']['params']['admin_driver'] = 'cyrus';

$conf['auth']['params']['drivers']['imp'] = 
array('driver' => 'application',
      'params' => array('app' => 'imp'));

$conf['auth']['params']['drivers']['cyrus'] = 
array('driver' => 'cyrus',
      'params' => array('cyradmin' => 'cyrus',
                        'cyrpass' => '<password>',
      'imap_dsn' => '{<IMAP-IP>/imap/notls/novalidate-cert}'));

$conf['auth']['params']['drivers']['cyrus']['params']['backend'] =
array('driver' => 'ldap',
        'params' => array('hostspec' => '<LDAP-IP>',
        'basedn' => 'dc=example,dc=com',
        'uid' => 'uid'));

if (!function_exists('_horde_select_loginscreen')) {
    function _horde_select_loginscreen() {
        return 'imp';
    }
}

Does anyone have an example config, or perhaps if you could tell me
where my mistakes are or point me in some direction..
Using CVS HEAD from Aug 14th.
Thanks.
