Feature: Automatic updates of SOA serial number
Reason: When multiple named processes shared one LDAP database and dynamically updated DNS record there (via DDNS), they didn't update SOA serial numbers so it was impossible to serve such zones on secondary servers correctly (i.e. they wasn't updated on slave servers)
Result (if any): The plugin now updates SOA serial automatically, if configured. Check "serial_autoincrement" option in /usr/share/doc/bind-dyndb-ldap/README for more details.
