[Pdns-users] Help with mydns backend

[Rob Campbell]

Thanks, at least I know it's not something silly I've done! I'd prefer to
move to the generic database backend as well but the plan was to use the
mydns backend to switch over quickly then migrate to the generic backend
later. Maybe we'll have to skip the mydns backend and get our data migrated.

Thanks,
Rob.
