[turba] lots of empty ldap connexions

[LALOT Dominique]

Hello,
I am checking some ldap access before going to production. And I found that
one of our ldap server is having strange empty connexions, there is maye be
10 connexions like this for a login and 3 for a single GetMail
That server is only configured in turba. So I post a turba question..
What is strange is to bind, and no search, no operation is done..
The source is OK, and I can search for names, mails and so on.
turba 3.0.10, php 5.3.6

my backends.local.php has a central shared ldap.
$cfgSources['localldap'] = array(
    'title' => 'Annuaire AMU',
    'type' => 'ldap',

If I look at horde log:
Nov 16 14:15:40 horde4 HORDE: [turba] Load config file (conf.php; app:
turba) [pid 12153 on line 865 of "/usr/share/php/Horde.php"]
Nov 16 14:15:40 horde4 HORDE: [turba] Load config file (attributes.php;

turba) [pid 12153 on line 865 of "/usr/share/php/Horde.php"]

and I also get 3 empty bind attempts when I check mail

Any idea?
Thanks

Dom
