One trick is to simply use Google to find likely source code snippets. I searched Google with the following query:

"use strict" "use Mozilla::LDAP"
[download]

I don't know much about the module itself, but it seems these are not just trivial examples, and may give you a leg up on how to use them yourself, if you don't find an app that fills your requirements.

Update: this was my 777th writeup.
