[Samba] Samb4 built-in ldap backend in standalone server mode !

[CpServiceSPb .]

I know about DC mode, that the server can act as standalone server in DC
mode. :))
But I need to avoid DC as set up parmeter because of in "native" DC mode in
Samba4 at the moment nmbd daemon doesn' t work officially.
But I need nmbd working as well.
So I needsome Samba4 mode unlike of DC but with ldap.
For standalone mode, if there is ldap or cldap are put in dcerpc endpoin -
there is a message that this components is not supported in standalonemode.
