Network Accounts are Unavailable message on MacBook Airs at boot up

I am trying to get some Macbook Airs to have wireless connectivity prior to users logging in so as to allow network authentication.  Is there a way to set up the Macbook preferences to make this happen?
We have WPA2 Personal and the Macbooks are bound to Active Directory.

I have figured it out. The latest version of Mac OS has an authentication piece called Captive Portal where the Macbook attempts to phone home. We have a Barracuda Web Filter which requires authentication and I had to set an exception rule for apple.com to permit that handshake. I set a domain exception simply out of ease and the fact that there is not any malicious or bad content on Apple.com which needs monitoring.
