bindrndc: no key definition for name rndc.key

Message error

/etc/init.d/bind9 restart
Stopping domain name service...: bindrndc: connection to remote host closed
This may indicate that the remote server is using an older version of
the command protocol, this host is not authorized to connect,
or the key is invalid.
