OK, the problem is the LDAP client (not DLZ, but the LDAP API's) evolved and don't like '%zone%' and '%client%' anymore.  The '%' symbol is used to escape characters in URL's.  There is a patch around that replaces all uses of '%' as delimiters with '$' so the LDAP API will work without complaint.  Find that patch, apply it, compile and change all '%' to '$' in your config and everything should work fine.

LDAP query isn't correct for the lookup query.  Post the DLZ section of
your named.conf so we can help find the error.

Dear ,
I tried to test bind-9.4.2 with DLZ and LDAP.
I recompile bind with DLZ LDAP option.
LDAP ...> OpenLDAP: slapd 2.3.27
and follow the example on http://bind-dlz.sourceforge.net/ldap_example.html
LDAP seems to be up and running also ldapsearch ok.
when I tried to start bind with   named -c /etc/named.conf  -d 20 -u 
named -g    I've got these logs:

[root@bindldap ~]# named -c /etc/named.conf  -d 20 -u named -g

Any one have an Idea about that error in RED.

Also note when I tcpdump I could not find any trial from bind to 
communicate with LDAP even local server or another remote one. otherwise 
ldapsearch did.

Thanks

Dear ,
Here are kindly find named.conf LDAP section.

dlz "ldap zone" {
        database "ldap 1 v3 simple
        {cn=mirghany,o=bind-dlz} {mirghany} {127.0.0.1}
