Then maybe we need to return all subjects, and not just the id, right? Or do
you want two strings for each subject? Id and netId (identifier)? Btw, to
return all subject info for all subjects with 540k of them takes a lot of

Remind me to ask you to explain this to me at the MM. :)

There already is a subclass (BaseSourceAdapter) which all sources should
extend. We could put in an implementation that throws an exception, and if
people want to implement they can, though I thought it would be hard to know
if you need to implement it or not, so I wasn't going to mention it... it's a
possibility though, and in this case might be useful since you only need it
(so far) with ldappc...
