In that case, if you use backports, you can get samba 4.1.11

 From 'man resolv.conf':

        The  domain and search keywords are mutually exclusive.  If more 
than one
        instance of these keywords is present, the last instance wins.

So domain dc1.domain.com.br is ignored.

You seem to be using a static ip, which is good but have you altered 
/etc/network/interfaces ?

If you install the following packages from backports, everything will 
get put into the right place:

samba attr krb5-config krb5-user ntp bind9 bind9utils dnsutils winbind 
libpam-winbind libpam-krb5 libnss-winbind libsmbclient smbclient
