samba - Apr 2004 - samba could not fetch trust account password for domain

I have installed Samba-tng as PDC. It works fine.

Now I'd like to install Samba-head server on same machine as domain
member and to auth users through PDC.
I have joined Samba to domain with smbpasswd -j KIROV.
It says Joined Ok.
But users can't see any shares on samba-head server.

smbd/password.c:domain_client_validate(1556)
  domain_client_validate: could not fetch trust account password for domain

  Defaulting to Lanman password for alex

I think it's well-known problem, but can't find the solution.
