Well, ldmi.net is a zone, sample.ldmi.net isn't.

Assuming $zone is "sample.ldmi.net", you're creating an update
for sample.ldmi.net; I think you need to have

  my $update = Net::DNS::Update->new("ldmi.net.");

or extract the zone name from your $zone appropriately.

That might depend on whether or not the names in your variables are
fully-qualified and terminated with '.' -- try and see.
