Subject: net_dns: Make "lwinet ads dns register" honor the "interfaces" parameter.
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=2fb742e127f725b56f308538852d7b10b86f29c1;p=thirdparty%2Fsamba.git

net_dns: Make "lwinet ads dns register" honor the "interfaces" parameter.

This is helpful on multihomed hosts that only require a subset
of IP addresses be registered with DNS.
(cherry picked from commit 17c9f8810598d8117befc896d12a597a52b0ac3b)
