I think you are referring to the stored procs, right? These are in the DB that you can restore from the database backup in the code download. Some stored procs were added to this DB backup after the book was published. Unfortunatly the scripts were not updated.
I can provide new DB creation scripts if anyone is interested. I've been working on 2 scripts: one to delete all the objects, and the other to recreate them all and populate the tables with data.
But there's still a few small issues with the AD module. You can't really disable them, for example. And you can't create a new .xml file when the database is updated.
But these are minor concerns...
