* Finish figuring out sane default key and value formats for the set of maps
  for which we're trying to provide default settings. (NIS)
* More tests.
* Stop using an internal function to send the LDAP result for failed searches.
* Reimplement / and // operator support to attribute references.
* Log messages at the right levels -- right now we log most everything at
  level "plugin" which isn't useful until you crank up the log level to
  ridiculous extremes.
