[Samba] Samba4 and Bind9

[Steve Thompson]

CentOS 6.2, Samba 4.0.0beta3, Bind 9.9.1-P1.

I have a workking Bind9 installation which includes several different zone 
files. Foward and reverse lookups work fine.

When I include

 	include "/usr/local/samba4/private/named.conf";

in the named.conf, named will no longer start:

Jul  9 15:01:47 s6a named[9857]: samba_dlz: started for DN DC=test,DC=cornell,DC=edu
Jul  9 15:01:47 s6a named[9857]: samba_dlz: starting configure
Jul  9 15:01:47 s6a named[9857]: samba_dlz: Failed to configure zone 'test.cornell.edu'
Jul  9 15:01:47 s6a named[9857]: loading configuration: already exists
Jul  9 15:01:47 s6a named[9857]: exiting (due to fatal error)

because of a conflict between an already included zone file and the Samba4
domain (test.cornell.edu).

What is the recommended best practice to fix this situation? I don't 
believe that I should have to add the offending zone's contents to 
dns_update_list; this seems like a hack to me. But then I don't have a lot 
of mileage with samba_dnsupdate yet.
