Will Active Directory and 802.11a/b/g Mix?

I have a network that is getting a new toy, a 3Com Wireless Access point that supports AES encryption. What i would like to do is setup the notebooks so that they can work wirelessly. Here is my issue: Connecting to the wireless network does not happen until after i log into windows. So does anybody know how i can have users log in via Wireless connection and still authenticate to Active Directory to get network shares and other options?Thanks!
