For now, the best approach would be to either add all these records to LDAP or to have it in a BIND zone file and synchronize between all FreeIPA DNS servers. I would recommend to simply use ipa dnsrecord-add command in a for cycle to add all the records. ipa dnsrecord-generate command could generate set of LDAP objects too and it would not require any changes in bind-dyndb-ldap...

Potentially yes, I just wanted to first have some assessment from Petr to see if it even makes sense from bind-dyndb-ldap POV. Maybe bind-dyndb-ldap cannot hook into the BIND zone file macro generation so the RFE would not even make sense.
