samba - Oct 2015 - Questions About Bind_DLZ

G'day Guys,

     Sorry for the delay.

     I've had the log level of samba at 5 for a while now.  Nothing 
interesting seems to be coming from the samba log.

     Increasing the bind logs, to level 5, shows nothing different. I 
get the same two warnings:

09-Oct-2015 12:46:01.421 database: warning: samba_dlz: Ignoring 
duplicate zone 'samba4.scem.westernsydney.edu.au' from 
'DC=@,DC=samba4.scem.westernsydney.edu.au,CN=MicrosoftDNS,DC=DomainDnsZones,DC=samba4,DC=scem,DC=westernsydney,DC=edu,DC=au'
09-Oct-2015 12:46:01.421 database: warning: samba_dlz: Ignoring 
duplicate zone '_msdcs.samba4.scem.westernsydney.edu.au' from 
'DC=@,DC=_msdcs.samba4.scem.westernsydney.edu.au,CN=MicrosoftDNS,DC=ForestDnsZones,DC=samba4,DC=scem,DC=westernsydney,DC=edu,DC=au'

Here is my named.conf file (Note: acls referencing IP Addresses for SCEM 
have been removed:

----------------------

acl "SCEM"    { KWD_Internal_Nets; PTA_Internal_Nets;
CTN_Internal_Nets;
KWD_Private_Labs_Nets; PTA_Private_Labs_Nets; KWD_Private_Staff_Nets; };

#acl "Server_ADM_Network" { server_adm; };

options {
     directory "/local/etc/named";
     allow-transfer { none; };
# Samba4
     tkey-gssapi-keytab "/usr/local/samba/private/dns.keytab";
#
     notify yes;
     forward only;
     allow-query { SCEM; };
     allow-update { key samba4.scem.westernsydney.edu.au; };

     dnssec-validation no;
     auth-nxdomain no;        # conform to RFC1035

     forwarders {
         IP.Address.removed;        # KWD-SCEM - internal DNS
         IP.Address.removed;        # PTA-SCEM - internal DNS
         IP.Address.removed;        # CTN-SCEM - internal DNS
     };
};

logging{
   channel simple_log {
     file "/var/log/named.log" versions 3 size 5m;
     severity warning;
     print-time yes;
     print-severity yes;
     print-category yes;
   };
   category default{
     simple_log;
   };
};

# Master Zones


#  Samba4
     include "/usr/local/samba/private/named.conf";
