[Samba] samba4 AD DC as file server?

[d tbsky]

hi:
   I want to setup a small samba4 server with AD and file server function.
I know that samba4 AD DC has no netbios browsing support. are there other
missing functions, like winbindd or something else?

  and if I install two samba4 instance, one to "/usr/local/samba"(for file
server), one to "/usr/local/samba-ad"(for AD DC). and give them two seprate
ip to bind. will it work better?

   thanks a lot for suggestion!!

Regards,
