Yes, no code, just need to add the appender to logback.xml. Locally, I
defined an idp.logDir = ${idp.home}/logs property. I have a tweak to
make to the testbed ldap, and then I was going to sync logging and
attribute config files from v2.

Yes, I was avoiding listening on a non-private interface. So, I guess
we should default to blank to listen on all interfaces, I can give
that a whirl too.
