This begs a few questions: Do you know, first, the SSID of the wireless network you are trying to connect to? Also, [...]

You need to first start by looking at Samba (samba.org) and specifically winbind and samba. Winbind will handle your connection to your AD and then configure Squid to use Samba/Winbind to authenticate users. There is great documentation on samba.org on how to do this under the Official How-To link.
