I've got a Drupal 6 site integrating with Active Directory by using the ldap_authentication module, and that side of it is working fine.

I need to make a directory of people in AD, using this module http://drupal.org/project/ldapdirectory and it's semi working; the dropdown box shows a few OUs but running any search gives me no results.

Someone who has configured this module before or who knows heaps about LDAP / AD come to my aid please! :)
