The search form at ldapcm/x/search doesn't list any directories; this is caused by a borked array address in ldapab.display.inc:
Line 139 is:
$form['dir_id_wrapper']['dir_id']['#options'][$id] = $dir->title;
... while it should actually be:
$form['search_form_wrapper']['dir_id_wrapper']['dir_id']['#options'][$id] = $dir->title;
Easy enough to fix hopefully :o)
Best regards,
