Badpwdcount query

Dear all.

I am writing a php-script that should read ldap-infos about bad logins and password expiry.
System: UCS 5.0, Windows-compatible, so Samba running on port 636 and openldap on 7636. Multiple servers, but i am only querying the primary for now.

I have tried on both ports, Samba on 636 looks like it has more info in it.

After reading Automatische Kontosperrung nach fehlgeschlagenen Anmeldeversuchen, I suspect, that failed attempts are not added from different sources, which would be okay, if I can query the the info of all possibilities.

Any help where to query would be much appreciated.
