[Samba] samba 4.9.5 - joining Samba DC to existing Samba AD failed

Hi team,
I have Samba (4.9.5) AD DC, and when trying to add second DC, join fail:

I have no idea, where is problem and how solve it - can anyone help?
Both systems runs Fedora 29 x86_64 Linux, Samba is builded with
Heimdal 7.5.0 Kerberos, tdb 1.3.16, ldb 1.4.6, first DC was provisioned
with '--use-rfc2307' and BIND9_DLZ (bind-9.11.5) DNS backend.
Thanks, Franta

You should only build Samba with the Heimdal version supplied with
Samba, you do not need to and shouldn't install Heimdal.

My mistake in description - I have installed (it seems unnecessarily)
only heimdal-libs package (no -devel ones) and samba itself is not
linked with it:
# ldd /usr/sbin/samba|grep heim
         libheimbase-samba4.so.1 => /usr/lib64/samba/libheimbase-samba4.so.1 
(0x00007f911e8da000)

Thus my problem should be something else - but what?
TIA, Franta
