We want to update our AD contact info from our HR system.  So I'm sitting
here looking at a giant spreadsheet that contains username, phone #,
department, title, etc. and wondering how I'm going to get it into AD.  I
know I can manipulate user accounts using dsmod, but it looks like dsmod
requires the DN for input.  I don't have the DNs - I have the usernames.
How can I go about this?

Thanks in advance!
