* 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.
* Reintroduce / and // operator support in attribute references.
* Look at moving the schema compatibility plugin to using a private database,
  so that it doesn't have to store everything it has in memory, we get working
  indexing, and so on and so forth.
