Hello,
I'm researching possibility of using Apache DS as DNS server.
How I understood DNS provider should started as standalone application.
I wrote next small program (in attachment).
Apache DS started,
When I start DnsServer, it starts listen 53'th port:
DEBUG [AWT-EventQueue-0] (DnsServer.java:62) - Apache DNS Service
listening on port 53
And command "netstat -anl | grep :::53", reports that 53'th port listens
somebody (it's 100% DnsServer, no one other):
tcp 0 0 :::53 :::*
LISTEN
But command "dig @localhost ya.ru", reports next:
; <<>> DiG 9.3.4 <<>> @localhost ya.ru
; (1 server found)
;; global options: printcmd
;; connection timed out; no servers could be reached
Reports must be different, for instance:
dig noexistent.nodomain
; <<>> DiG 9.3.4 <<>> noexistent.nodomain
;; global options: printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 9446

What I'm doing wrong?
Partition "dc=example,dc=com" exists, but it empty, I don't know what
insert to it. If reason in it, can you send me example dns ldif file?
ps: I very new in DNS.
pps: sorry for my English.
