The ldapsearch line is setting both a treebase and a search filter. Neither
is present in your ActiveLDAP query. In addition you're passing what you
think is a filter string to Entry.find, whereas it's looking for a DN. (Both
queries are binding anonymously, which is unusual, but you'd have gotten a
different message from ldapsearch if that were a problem.)

Look into the Net::LDAP library on Rubyforge, also installable as a gem. It
has a reasonably complete rdoc, including some theory of how LDAP queries
work.
