I have a Meraki wifi network that's authenticating via RADIUS to an Active Directory. Users log in with their AD username and password via WPA2. That all works. However, when a user changes their AD password (due to expiration, forgotten password, whatever), their Mac doesn't prompt for a new password; instead, it just can't connect to the wifi. To fix this we have to go into Network Preferences -> Advanced -> Wifi -> Preferred Networks, delete the network, then make a new connection. This is kind of clunky, and gets us a helpdesk call every time.
Any ideas on what we could do about this?
A possiblly easier thing to do is delete the keychain entry for the wifi, or just change the password in keychain. Sorry I don't have a better option off hand.
A talk with Apple tech support says that, indeed, there's no automatic way to do this. 10.8 doesn't seem to have changed this behavior.
