I'm trying to add a CNAME to a zone file, which when named is restarted should update a slave DNS server, but doesn't. I can add an A record and the slave zone file updates, but when adding CNAME it doesn't.

I've tried providing examples, but if what I'm writing here posts, then I can't post if I include the examples.

I don't get any errors when I restart named (rcnamed restart), but the slave zone file is not updated.

Any ideas?

Thank you.
