Windows machine has to join two times

Hi,
I'm running a debian lenny machine with samba (3.5.0) and OpenLDAP installed
(2.4.11). When i add a machine to the domain, windows reports the following
error: "The specified computer account could not be found". The computer
account is added to the LDAP database but without the samba attributes. The
weird thing is that if i try it a second the, the samba attributes are added to
the computer account and the machine successfully joins the domain. This
happens with XP, Vista and Windows 7 cliënts. I have no idea why it doesn't
work the first time.
On the internet and in this mailing list i found other people where the samba
attributes aren't added but i didn't find anyone where it does work on a second
attempt.

Log after the first try (fail):

I don't think it has anything to do with the "Authentication for user [qsdf] ->
[qsdf] FAILED with error NT_STATUS_NO_SUCH_USER" error because the second time
it does work. Although i have no idea what this error is and if I should fix
it.

The add machine script should be good. Samba should add the samba attributes,
not ldap (regarding the manual).
