samba4 in a windows AD forest

I manage the network in a small research laboratory (20 people) wich are in a large research institute. Quite all laboratories of this intitute are in a forest managed with windows AD servers and DNS bind servers. 

In my lab, we bought a new server (Power Edge T620) to create a DC (we don't have one right now) and improve files sharing. 
I installed ubuntu 12.04, removed samba3 that I used to make first file sharing tests and compiled samba 4.1.1 

I am going to traduce your how to on french ubuntu documentation web site : 

I have attached a network diagram and the extract of provisioning 

When I tried to run samba, I have 
Failed to bind to 53 TCP - NT_STATUS_ADDRESS_ALREADY_ASSOCIATED I don't understand well interactions with DNS server. I have no DNS in my lab, the DNS I used is on "partner lab" (illustrate in diagram). I think I should declare DNS backend BIND9_DLZ but at I read 
"Configuring Bind as Samba Active Directory backend 

    * Note: Bind must be installed on the same machine as samba." 

Could you clarify? May I used the DNS of my "partner lab" ? 
Otherwise, may I continue to use their DNS and run Samba4 without join the forest? ... or must I use Windows Server :-( 

Thanks for any help .
