It's been a while since I've worked against an LDAP server, but this general
query information might be helpful.
If you don't get any records back, the query shouldn't fail; instead, it
should just have no records. You can use the RecordCount query variable
(myquery.RecordCount) - if it's zero, your query is empty.
