It sounds as though your name server is behaving perfectly correctly.
It should respond authoritatively to queries for records in zones it's
authoritative for and non-authoritatively to queries for records
outside of those zones.
What you're probably noticing is a behavioral change between BIND 9
name servers and earlier versions of BIND. When BIND 9 name servers
go off and look up the address of cnn.com for you (for example), they
return that as non-authoritative. Older BIND name servers would
return the same answer as authoritative the first time. (Successive
responses from the cache would be marked non-authoritative, of course.)
