Master and slave servers should both be authoritative for the zones they
host.

If the slave isn't authoritative, it isn't transfering the zone properly
from the master. Here's a command that show this:
$ dig comcity.com soa @ns2.comcity.com +norec
; <<>> DiG 9.2.2 <<>> comcity.com soa @ns2.comcity.com +norec
;; global options: printcmd
;; Got answer:

comcity.com. 1000 IN SOA ns.comcity.com.
hostmaster.comcity.com. 2004042001 3600 900 604800 3600
Notice that the "flags:" field doesn't have the "aa" (Authoritative
Answer) flag. Also, the TTL is lower than it is on the master; this
indicates that the information came from the server's cache rather than
from a zone file. Compare this with the result from the master server:
$ dig comcity.com soa @ns.comcity.com +norec
; <<>> DiG 9.2.2 <<>> comcity.com soa @ns.comcity.com +norec
;; global options: printcmd
;; Got answer:

;; QUESTION SECTION:
;comcity.com. IN SOA
;; ANSWER SECTION:
comcity.com. 3600 IN SOA ns.comcity.com.
hostmaster.comcity.com. 2004042001 3600 900 604800 3600
You've been struggling with this for at least a week. I think it may be
time for you to give in and hire a professional who knows what he's
doing.
