I am surprised no one has answered this yet. I was very curious to see the answer myself. I am looking into the same thing; I have not been able to research a lot, but I have found out that the ad data resides in a database, so presumably that is why crystal doesn't have any special means to accessing it. I am going to work with our sys admin to find out more. Please let me know if you find any great documentation, etc on this. Good luck!
