Hi Michael, thanks for the reply.

I simply had left this part of the config as it was (working before 
upgrade) at version 4.1.14.

Obviously, bind suffix support was dropped at some point, probably 
because the bind backend can be launched only once anyway, so suffix 
support does not provide any benefit. Looking at Authoritative Server 
change logs, I found, at v4.2.0:

      bindbackend: Refuse launch suffixes. References: pull request 6558

I tried with:

    launch=ldap:bkend1,bind

    ldap-bkend1-host=localhost
    ldap-bkend1-basedn=ou=dns,dc=noa,dc=gr
    ldap-bkend1-binddn=uid=dnsusr,ou=sys,dc=noa,dc=gr
    ldap-bkend1-secret=oursecret
    ldap-bkend1-method=simple

    bind-config=/etc/pdns/bind/named.conf
    bind-check-interval=600

and it works indeed.

Cheers,
Nick
