The IP address for host edex.esci.millersville.edu resolves to a single hostname: -bash-3.2$ dig -x 166.66.65.219 ... ;; ANSWER SECTION: 219.65.66.166.in-addr.arpa. 28 IN PTR edex.esci.millersville.edu. ... But the IP address for host edex-test.esci.millersville.edu resolves to multiple hostnames: -bash-3.2$ dig -x 166.66.65.102 ... ;; ANSWER SECTION: 102.65.66.166.in-addr.arpa. 3304 IN PTR gc._msdcs.muad.local. 102.65.66.166.in-addr.arpa. 3304 IN PTR edex-test.esci.millersville.edu. 102.65.66.166.in-addr.arpa. 3304 IN PTR es.muad.local. The ALLOW entries on our servers will allow .edu-s but not .local-s. If a reverse DNS lookup on the IP address doesn't return the .edu hostname, then the connection won't be allowed. Can you reduce the canonical hostnames to one?
