[Samba] Samba4 and Bind9

[Steve Thompson]

Samba 4.0.0beta4, CentOS 6.3.

It seems to me that when samba updates its DNS entries by processing a 
dns_update_list entry such as:

 	A ${DNSDOMAIN} $IP

then:

(1) it is using the Kerberos realm name for DNSDOMAIN rather than the DNS 
domain name. Indeed, it seems to me that there is quite a bit of confusion 
between the two throughout Samba4.

(2) when a second or third DC is added, the value for $IP inserted in the 
second or third DNS is the IP address of the first DC, not that of the 
second or third. Huh?

I would _like_ the realm name and the DNS domain name to be the same, but 
it appears that one cannot do that: bind9 will no longer start, as I 
observed and reported previously.
