Hello,

I am using a few LDAP addressbooks, a few global read only books and
one personal addressbook.

The synchronisation from LDAP to activesync devices works fine.
A new entry from the webfrontend to LDAP and the activesync clients 
works fine.
Entries on LDAP are recoginzed on the webfrontend, with the known 
"bug" that activesync devices are not aware of a change/new entry.

If I try to add a new entry on my cell phone, it isn't created in the
LDAP backend, because of a missing cn field. I use the evolution 
schema on openldap.

My relevant part of backends.local.php:

$_ldap_uid = $GLOBALS['registry']->getAuth('bare');
$_ldap_basedn = 'dc=mydomain,dc=lan';
$cfgSources['personal_ldap'] = array(
     // Disabled by default
     'disabled' => false,
     'title' => _($_ldap_uid . " addressbook rw"),
     'type' => 'ldap',
     'params' => array(
         'server' => 'ldap.mydomain.lan',
         'tls' => false,
         'root' => 'ou=' . $_ldap_uid . ',ou=Personal,ou=addressbook,'

     'browse' => true,
);

In my Driver.php "name" maps to "fileas"

The error in the activesync log is the following: (Name Motojj Tester,

Let me know, if you need further logs / config files.

Thanks and regards
