I am having an issue with macbooks trying to authenticate via wireless when they are within my network. They are bound to AD and the users that login have mobile accounts created from AD. How can I stop this or fix this so they can login. Right now as it is, if a staff member brings their school issued laptop in and tries to login with the wireless on, it will just sit at the login screen trying to login. We either have to plug the machine hard wire into the network or reboot the machine and login as a local admin and shut off the airport. Any ideas?
