It's been a decade since I had access to this area. So your first call is to Apple to see if they have a patch or setting. Next is Microsoft to see if they have any updates.
As to WPA2 I don't see how that matters here.
We have an issue in all our mac laptops, we could not get the password expire notification to the Active directory users, we are using wpa2 security type wifi connection, when we connect to the ethernet it showing the password expire days at the login screen, but in wifi it wont show this, how can we get the notification to the user while using wifi connection, please help on this
also some of the laptops are not showing ( (Allow network users to log in at login window)) then we need to unbind the domain and rejoin , after this fix it shows the options, need assistance on this why it not showing for some users
