ActiveDirectory As A Dataflow Source

Has anyone in here had luck using AD as a datasource? Big picture, we have an input file with unique identifiers (employee clock numbers) and I need to associate a clock number with an email address. The only place we have those two together is in Active Directory.

Currently, we have a lookup task with an OLE DB connection to our AD and a query that looks like



Code Snippet
SELECT mail, clockNumber
FROM 'LDAP://DC=company,DC=com'





I've mapped my input to the clockNumber in AD and all is well and good. I then go to thinking, perhaps it'd be better if I used that query as a source in an OLE DB component and used a Merge Join to make the link between the two. I paste that same query into a source component and boom

Is this just not something that a person can do or is there something I've set up incorrectly? I'd be lucky to be considered a novice with AD so I'm fine if someone has a better suggestion for retrieving this data, this was just something I'd cobbled together out of some forum postings.
