Bind 9.9.4 DLZ LDAP , error in config file named.conf

Thu May 4 16:50:32 UTC 2017

Dear Enrico,

I have never configured DLZ zone myself.
There is clear error: all nodes query must specify a search base
I think it did not parse some query uri well. Could you add at least -d 1 to OPTIONS in /etc/sysconfig/named and retry?
It will provide more details about query before it fails.

Just to be sure, do you really want ou=dns,dc=priv for lines 1 and 2, but ou=dns,o=bind-dlz for lines 3 and 4? Are your data split between them?

Best regards,
Petr

Subject: Bind 9.9.4 DLZ LDAP , error in config file named.conf

Dear All, let me explain my issue. 
I've CentOS 5.5 with Bind version 9.6.1 and the most important item for this setup 
is the integration with Ldap throught DLZ. So as you can imagine I've named.conf 
with ldap servers but I haven't any zone file because all informations 
about hostname and IP are inside Ldap. 
In the following my named.conf file: 

options { 
directory "/var/named"; 

listen-on-v6 { none; }; 
listen-on { 127.0.0.1; ...... 
omissis 
................ 
pid-file "/var/run/named/named.pid"; 
}; 
..... 
dlz "ldap zone" { 
database "ldap 1 v3 simple {cn=Sync,dc=priv} {PASSWORD} {10.0.0.1} 
ldap:///dlzZoneName=%zone%,ou=dns,dc=priv???objectClass=dlzZone 
ldap:///dlzHostName=%record%,dlzZoneName=%zone%,ou=dns,dc=priv?dlzTTL,dlzType,dlzPreference,dlzData,dlzIPAddr?sub?(&(objectClass=dlzAbstractRecord)(!(dlzType=soa))) 
ldap:///dlzHostName=@,dlzZoneName=%zone%,ou=dns,o=bind-dlz?dlzTTL,dlzType,dlzData,dlzPrimaryNS,dlzAdminEmail,dlzSerial,dlzRefresh,dlzRetry,dlzExpire,dlzMinimum?sub?(&(objectclass=dlzAbstractRecord)(dlzType=soa)) 
ldap:///dlzZoneName=%zone%,ou=dns,o=bind-dlz?dlzTTL,dlzType,dlzHostName,dlzPreference,dlzData,dlzIPAddr,dlzPrimaryNS,dlzAdminEmail,dlzSerial,dlzRefresh,dlzRetry,dlzExpire,dlzMinimum?sub?(&(objectclass=dlzAbstractRecord)(!(dlzType=soa))) "; 
}; 

Ldap server is OpenLdap 2.4.11 with DLZ schema, with this setup name resolution for zones "*.PRIV" works fine. 

This server is up and running from many years but now I need to update to Centos 7, but 
with this OS update I also migrate to Bind 9.9.4 included in the last Centos and this is my problem ! 

Bind 9.9.4 with named.conf describe above failed during startup. When I make "systemctl start named.sdb" 
I've this error: 

Job for named-sdb.service failed because the control process exited with error code. See "systemctl status named-sdb.service" and "journalctl -xe" for details.
