To be honest, I doubt you will be able to fix it with
version 2.2.12 of Samba. It *might* be that you can
configure W2K8R2 to use ancient authentication mechanisms,
but I would recommend upgrading Samba.

"security=domain" and "winbind rpc only=yes" should be
possible anywhere.

Latest Samba 3.5.6 should compile fine there. If it does
not, we'll be happy to fix the build breakages you find. We
don't provide binary packages, so you'll have to compile it
