samba - Feb 2012 - net ads join disable dns update

We have a couple oracle RAC servers that we install samba/winbind on. These
servers require multiple NIC's / IP's.

The problem is when we do "net ads join" it updates windows DNS and
really screws us up because seven IP's get put into DNS, all tied to the
same host, including the interconnect IP's which oracle insists needs to be
169.254.x.x addresses. Because of the way the company is setup, we cannot
disable DNS update on the windows server. The company relies on it for most of
the machines.

We are using the 3.5.12-44 rpms from ftp.sernet.de.

I have Googled this for awhile now, and what I've found is that Samba should
be recompiled with the the "--with-dnsupdate" flag. This really
isn't an option for us. I've also seen that if its in an smb cluster
auto-update will disable. I've also seen a lot of complaints about this and
a reference saying that a command line option was going to be added similar to
"net ads join --disable-dns-update" but that doesn't appear to
have been implemented.

So, the question is, is there entry that can be put in smb.conf, a command line
option, startup option, anything (other then recompiling) that can disable dns
auto update?

Been there:
1. Compile Samba by yourself, remove WITH_DNS_UPDATE flag.
2. Disallow "allow insecure update" from DNS server.
3. Edit /etc/hosts, use shortname for your Samba server, then upon "net ads
join
" it will complain domain name not found hence will not update DNS.

Cheers
