The PureMVC Framework Code at the Speed of Thought

Started learning puremvc this week by working though the best practices example to make a working login system. (That pdf is wonderful btw, with each turn of the page comes a new revelation)

I got the login system to work apart from one thing - authToken. Any reference to it I just commented out.

"Set by the server if the credentials are valid". No it isn't What type of token? Where do I get it from? How, and when, do I inject it in to the loginVO? (using cflogin against database validation)

I'm sure I'm going to slap my head and go "duh!" once I'm told the solution, but for now my brain is frazzled enough after only two days of getting to grips with the framework.
