Description of Problem:
Even after making required changes to named.conf, one cannot use rndc.

Actual Results:
rndc: send remote authenticator: permission denied

Additional Information:
Hacked by changing name of key from "key" to "rndc_key" and all is well 
now. Could the parser have been fooled?

Also, it would have been nice if I didn't have to rtfm and edit named.conf 
with a basic rndc (key; controls;) setup. ;)
