Because I want to try set multiple key. Currently I have only one server (localhost - 127.0.0.1) but in future on real working network I would have to setup more than one server and I don't know how. I will have to simply add new key to the allow-update or allow-transfer option?

Bind version is: 9.7.4

Maybe this is a stupid question but what is ARM?

The key is in a external file.

Without that (keys only in server section) I can transfer whole domain (dig my.zone axfr) without passing any key.

Named-checkconf returning an error with "}" expected after ";" and ";" expected after "}".
