[Samba] ldap and computer accounts

I'm attemtping to configure a Ubuntu server for a bunch of windows clients.
I'd like the authentication information to be in ldap.So far the stuff
works,
I can authenticate users in LDAP just fine.

But when I want a windows machine to join the domain I get the
error 'The user name could not be found'. The computer account
gets created (via smbldap-tools) and I can see it in the ldap.
The samba log shows what's happening, when id can not find
the account it creates it and fails when it can not find the freshly
created account. Unfortunately the log is net very helpful to point
find out what is wrong:
-------------------

How can I debug and fix this situation ?
