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?

I'm trying to clarify what I'm looking for. I felt that the old title was misleading, and thus causing people to not look? Sure, I'll put a bounty on. – Bill Weiss May 9 '12 at 22:43
I've filed an Apple bug report, #11419560. – Bill Weiss May 9 '12 at 22:53
My bug has been closed as a duplicate of 10996590, which I can't see. Thanks, Apple. – Bill Weiss May 12 '12 at 4:21

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.

That's an interesting idea. Not much easier than poking at the Network Preferences manually, but many easier to automate? Dunno. I probably don't want an automatic job that deletes keychain entries :) – Bill Weiss May 10 '12 at 0:21
I would write a script or small app that would allow the user to do this on their own. You can remove these entries by deleting a plist (I forget which one though). – Joseph Kern May 11 '12 at 22:20
Login.keychain is the file, but that hold everything. I don't know of a way to just remove a single keychain entry through a script. – Joe van Maldegiam May 11 '12 at 23:06

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.
