Actually, the passdb you use is not of consequence to this issue. A
machine account on a Windows domain is somewhat like a user account in
that there is an SID and a password that are readily understood by both
the machine joined to the domain and the domain controller(s). That
password is going to be stored on the domain controller in whichever
form of passdb a samba DC is using.

Each domain would necessarily have a different SID and that SID affects
all systems and users. 

If you have 2 domains and a number of Windows computers attached to both
domains and you want to consolidate into one domain, there really is
little choice but to join the Windows computers to the one remaining
domain as there is no simpler way to change the SID of the machine to
the other.

If you have user profiles that need to be saved/migrated from one domain
to the other, see the samba documentation for a comprehensive discussion
on migrating user profiles.

Thus, this never was an LDAP question but if you are talking about the
openldap mail list, they are very provincial that the discussions on
that list are specifically about their software and not about
integration. If you want mailing lists where ldap integration is
appropriate, you might want to check ldap at umich.edu [1] and ldap-interop
