using roundcube cache

Hi all,

while experience a very slow webmail interface I was looking for ldap
queries in roundcube debug.

E.G. for looking for calendar entries I found a lot of lookups every
time I switch week - even if I go back again.

In my config.inc.php there is ldap cache enabled - but


    // LDAP Settings
    $config['ldap_cache'] = 'db';
    $config['ldap_cache_ttl'] = '1h';

and neigher

    // LDAP Settings
    $config['ldap_cache'] = 'memcache';
    $config['ldap_cache_ttl'] = '1h';


helps anything. I see - every time ldap server lacks it tooks a lot of
time until calendar is displayed.

Does the ldap_cache settings in config.inc.php affect calendar? Or is
there an special cache for that?

Thanks and regards
Jan
