Synchronizing new users to CA

I am trying to add a new Reviewer, but before I add him, I need to be able to see him as a CA Users (I assume)

When adsyncronizer runs I get the following in my event log: When it say "existing users" does that mean AD or CA existing users. I don't see the user that's in AD in CA after synchronization.
