[Pdns-users] [LdapBackend] avoid writing PdnsDomainNotifiedSerial

[Michael Ströder]

HI!

I have a very tiny and simple setup of PowerDNS Authorative server(s) 
4.5.3 with LDAP backend using native OpenLDAP replication. Each pdns 
instance asks a single local LDAP server (via ldapi://). No need for 
AXFR or IXFR or anything similar fancy in this setup. Also no LDAP 
fail-over to multiple replicas.

pdns tries to write attribute PdnsDomainNotifiedSerial even though it is 
IMHO not needed in my setup. It fails because the LDAP server is 
deliberately configured to not allow write access from the pdns service. 
Also a pure read-only consumer replica does not accept write operations.

Which configuration setting can I tweak to suppress writing 
PdnsDomainNotifiedSerial?

Many thanks in advance.

Ciao, Michael.
