No worries, mate :-)

DsAddEntry is a bit like LDAP Add, but for special objects like the
NTDS Settings you see above, because there is special processing done
server-sdie.  My guess is that we have something in that new NTDS
Settings object (for the Samba DC) that it doesn't like.

This may have been unfortunate.  Samba is likely more flexible than
windows, and joining the modern version of Samba to that, rather than
directly to the 2003 server, might have been a way forward.

That sounds frustrating to work with, but the info so far is good
enough. 

I think what is happening is that the partition list (NC is naming
context, which we also call a partition, being the AD domain, config,
schema and 2x dns partitions) that we think we should say we host isn't
lining up with what the DC thinks it has. 

What functional level is the domain?

Do you need Samba joined to the domain long-term, or where you joining
it to access the secrets (we have some tricks for replicating the data
without creating the DC objects if that would help). 

If you can let us know a little more your purpose here we may be able
to figure another way out.

Thanks!
