samba - Dec 2012 - S4 AD Domain Up; but no DNS auto-registration

samba-4.0.0 x86_64, CentOS6.3

My Samba4 / AD is up and running after migrating this weekend.  Testing
looked good and the domain *is working* but there are some issues.

Automatic DNS update is not working.  Workstations seem to be
registering their names but joining a server to the domain works but
fails with a error - and the DNS record is *not* added.

[root at crew etc]# net ads join -U Administrator
Enter Administrator's password:
Using short domain name -- BACKBONE
Joined 'CREW' to realm 'micore.us'
DNS update failed!

When using the BIND server, but not the internal DNS server, this
happens for Samba clients only.  We have modified the Samba client in
4.0 to also work with BIND, and we need to get back to the BIND folks
about the issue.
