-ZZ is also successful.

It would be also interesting to see your ldap related pdns.conf settings.

The only two things I have are:
launch=ldap
ldap-basedn=ou=hosts,dc=foobar,dc=com

I tried setting the host explicitly to IP address, URI, etc. Didn't help.


Does "netstat -lp" shows open connections from your box to the LDAP server?

Yes. Please see below: (Both pdns and sldapd are on the same machine.)

# netstat -lp tcp
Active Internet connections
Proto Recv-Q Send-Q Local Address Foreign Address (state) tcp4 0 0 localhost.ldap localhost.53006 ESTABLISHED tcp4 0 0 localhost.53006 localhost.ldap ESTABLISHED tcp4 0 0 localhost.ldap localhost.53625 ESTABLISHED tcp4 0 0 localhost.53625 localhost.ldap ESTABLISHED tcp4 0 0 localhost.ldap localhost.64231 ESTABLISHED tcp4 0 0 localhost.64231 localhost.ldap ESTABLISHED tcp4 0 0 localhost.ldap localhost.63398 ESTABLISHED tcp4 0 0 localhost.63398 localhost.ldap ESTABLISHED


btw, there is another behavior I don't understand, but might help with debugging this issue. During my successful non-TLS mode operation, I noticed that all my successful dig responses still had the ";; WARNING: recursion requested but not available" message. I noticed on pdns' logs that it was sending that warning to the client every time a successful lookup happened. Maybe this is completely unrelated.

Please let me know if there is anything else you would like me to check.

thanks
