samba - Nov 2005 - No account in domain for workstation after upgrade

Hi,

I'm trying to upgrade an old samba-ldap PDC (2.2.x) to a newer one. I
use the same machine, so i've dumped the ldap database and imported it
on the new config (using the perl script provided in samba to convert
accounts), edited all my config files, and then started the new PDC. All
seems to run fine, smbldap-tools still works, but there is a problem on
windows workstations. When a user try to login it fails saying that they
cannoct contact the PDC or the workstation is not allowed to login. In
samba's logs i've got the following error message :


[2005/10/24 12:16:32, 2] passdb/pdb_ldap.c:init_sam_from_ldap(511)
  init_sam_from_ldap: Entry found for user: ISABELLE$
[2005/10/24 12:16:32, 0] rpc_server/srv_netlog_nt.c:get_md4pw(261)
  get_md4pw: Workstation ISABELLE$: no account in domain

But the account exist in ldap, and looks fine.
The only solution i've found do far is to rejoin the domain on the
workstation "using network id wizard".
Is there any way to solve it on the server side ?

Your advise will be much appreciated.
