samba - Feb 2011 - samba 3.5.6 pdc ldap backend and windows 7

Hi,
as I found a lot of postings in web concerning the :
_netr_ServerAuthenticate3: netlogon_creds_server_check failed, . Rejecting auth
request from client ...

but not any solution for this issue, maybe I've missed one,it would be very
nice if somebody solved this issue, to share the findings, or better the
solution should be written down at http://wiki.samba.org/index.php/Windows7

kind regards
Manfred
