samba4 from BDC to PDC

Hi all,
in my simple network I have:
- MS SBS2003 server which is PDC and master DNS (allow zone transfer to
other DNSs of the zone)
- Ubuntu 10.04 32b server VM on XEN server with samba Version
4.0.0alpha17-GIT-ccaab14 joined to the AD domain as DC plus dhcpd
configured for ddns updates (currently to the SBS DNS) plus BIND
9.8.0-P4 configured as slave DNS for the local domain zones
- Ubuntu 10.04 32b server with samba Version 3.4.7 joined to the AD
domain which acts as file server (for the network shares)

My goal is to remove the SBS server so as first step I'll disable zone
transfer from the MS DNS and change the zones in BIND to master to check
if samba4 DDNS and ISC DHCPD DDNS still works but as per the samba4
how-to I need to add the tkey-gssapi-keytab
"/usr/local/samba/private/dns.keytab"; statement in named.conf.

If I run provision on samba4 (for a new domain) at the end of the
provision the dns.keytab file is created in the samba/private directory.
Running the domain join command instead of the provision the dns.keytab
file is not created so how am I supposed to proceed?

Thanks in advance,
