[Samba] Member join, dns issues

[Greg Sloop <gregs@sloop.net>]

How important is the reverse, PTR record?

The zones for the IP blocks aren't "owned" by the Samba DC, but by our
internal BIND/DHCP servers. Adding a bunch of reverses for IP's will be
additional hassle. If they're not critical, I'd probably live without them
for now, at least.
