that will work. Search for "WiNG 5.X How-To - Active Directory Authentication". This PDF include all descriptions for the scenario.
Do you have a PKI? I prefer to provide a private certificate for every AP to secure the authentication. Biggest problem with MSCHAPv2 is, that most people disable the certificate validation. Use a trusted certificate or publish the AP certificate to every computer via GPO. Do not disable certificate validation!
The setup goes like this, when the user logged in his/her AD account, he will be automatically be connected to the wireless network. The AP will use the user's AD login credential as authentication. Will this be okay?
