[Samba] domain RODC fails with default provisioning

[Andreas Calvo]

We're evaluating joining another samba domain controller in read-only mode.
With a default provisioning, when running the samba-tool domain RODC, it
fails with the following error:
ldb: ldb_trace_request: (tdb)->search
ldb: ldb_asprintf/set_errstring: NULL Base DN invalid for a base search

Is there something special to be done prior to the domain join command?
