Since the user hasn't "touched" the Site Collection yet, they aren't in the User Information List.
The trick would be to add them to ssomething in the Site Collect. Then they would be in the UIL and have an SPUserID.
Also take a look at the ResolvePrinciple operation. I'm not sure if it'll help, but it sound promising?
