Great, got it. So what's happening is this:

samba_dnsupdate tries to negotiate a TKEY exchange for a
cryptographically signed update, but the internal server doesn't
understand that record type yet (in master, working on this stuff right
now). Because the server thinks the record type is invalid, it returns
FORMERR. This should hopefully be fixed soon, but in the meantime, try
the following workaround:

In smb.conf, set

nsupdate command = nsupdate
allow dns updates = True

That will allow unsigned dns updates to you zone, so it's not the most
secure option, but it should work.
