A couple more things:
1) smbldap-populate initializes the sambaGroupType for all the
S-1-5-32-* SIDs to 5. This is incorrect. It should be 4, but this
probably isn't causing this issue.
2) I think that root needs to be in the Domain Admins group in order
to join a machine to the domain, not the Administrators group which is
a local group. At least that is how I am set up.
3) Depending on the details of your implementation you may not need to
use smbldap-tools at all. Have a look at the ldapsam:editposix and
ldapsam:trusted on the smb.conf man page. Note that using
ldapsam:editposix is one case where winbind is required on a Samba PDC.
