Thanks for the answer!

Is that true if we have Subdomains, Samba write to DB information only about join-domain?

And what option --domain-critical-only do? I did not see the difference -  with or without.

Samba replicates no additional information to be the GC, so it won't help.  In Samba, the GC port is just another view of the main databse.

The Global Catalog would only be different if we supported sub-domains, which we don't.

If there is 16GB of data, then Samba simply won't be able to hold it, no matter what, due to the TDB limits (let alone the structural limits that blow up well before then).
