[Samba] (S4) Neither AXFR nor authoritative nameserving available?

[Michael B. Trausch]

Hello all,

I'd like to have redundant DNS in our setup.  But it seems that Samba 4 
does not yet support AXFR with its internal DNS server.  Alright, that's 
fine, so I figured I'd configure the system such that at the very least, 
a caching nameserver was sitting in front of it.  However, that doesn't 
work; the caching nameserver (BIND 9) returns SERVFAIL, apparently 
because Samba 4 isn't setting the authoritative bit on its DNS responses.

Is this a known issue, a configuration error on my part, or something 
entirely different altogether?

	Thanks,
	Mike
