Ok,  so it seems that smbd is not using clustering/ctdb then and
instead is using the local
non-clustered tdb files : /var/lib/samba/registry.tdb

This is definitely the problem why it is not working.   Now,   why is
samba running in non-clustered mode using local tdb files?  that is a
different question.
