webservice: object is modified instead of created

When creating an org with:

$odata['organization']['o'] = 'xxx';
$odata['organization']['description'] = ...
$odata['organization']...

$fdresult = $client->setfields($session_id, 'organization', NULL, $odata);

Note that I'm using 'NULL' because I want to create a new org.

In LDAP logs I get this 'new' string to appear :

... filter="(&(?roleOccupant=new)(&(objectClass=organizationalRole)(!(objectClass=simpleSecurityObject))))"
...
filter="(&(?member=new)(objectClass=groupOfNames))"
...
conn=18049 op=1 do_search: invalid dn: "new"

(Once again I do not get zero error back from the webservice about this...)

The final result is if the organization 'o=xxx' already exists, it is somehow modified instead of created as asked (ie: it should raise an error that this org entry already exists).
