Samba4 + Bind DLZ at FreeBSD 8.3 !

[oooo1 at front.ru]

We have built Samba4 alpha18 (not alpha19) successfully at FreeBSD 8.2-8.3.But we can' t make workable Bind dlz when include "/usr/local/samba/private/named.conf"; ordlz "AD DNS Zone" { database "dlopen /usr/local/samba/lib/bind9/dlz_bind9.so"; };
in /var/etc/named.conf 
Bind doesn' t start with either ... or line.As we have found out BInd works its instance in jail at FreeBSD.
Who can help ?
