Matt (sorry for the delay),

I'm making an assumption that when you say "we were able to change our password 
correctly", you did that be changing it in Lion?

The issue I was referring to is this:
- via your institution's account management service, create "password1" and use 
it to connect to your SSID
- "password1" is stored in the keychain on the Lion machine
- via your institution's account management service, change password to 
"password2"
- Turn on Wi-Fi on the Lion machine and it'll try and use "password1", which is 
stored in the keychain. It'll fail and wait ~60seconds before trying again with 
"password1". In my testing, I was never prompted to re-enter my password. Thus, 
flushing keychain was the only option.

Hello all,

We tested for this bug on our test OS X Lion device and we were able to change 
our password correctly.  Did we not do something right to get this bug to 
appear?  I want to make sure we tried everything as our students will be 
returning starting this Wednesday.

Thanks,

Matt

All,

Per advice from our Apple rep, I have submitted Apple BUG# 9922069. If you 
would, please also submit bug entries for this so they understand the affect of 
this issue. For your ease of submission, here's what I
submitted:

09-Aug-2011 02:23 PM Ryan Holland:
Summary:
After successfully authenticating via 802.1X to an enterprise Wi-Fi
network, credentials are stored in Keychain correctly. If the
username/password are changed on the enterprise side (i.e., user
changes their password), OS 10.7 continues to use the stored keychain
item and never prompts the user to reenter their username and
password. Authentication continuously fails.

Steps to Reproduce:
1.) Connect to an 802.1X authenticated WPA2-AES enterprise Wi-Fi
network (like most higher education institutions) and verify
credentials are stored in the keychain.
2.) Change username and password via the authentication database
3.) Disconnect from Wi-Fi on the 10.7 machine.
4.) Reconnect/reauthenticate to Wi-Fi
At this point, reconnection is not possible.

Expected Results:
OS 10.7 will use the keychain with the now-incorrect username and
password. Upon failed authentication, the UI should prompt the user to
reenter their username and password. User would enter their
now-correct username and password, successfully authenticate, and OS
10.7 would update the keychain entry appropriately.

Actual Results:
UI never prompts for now-correct username and password. Authentication
continuously fails.

Regression:
User must manually remove any and all related keychain items that have
the stored username and password. Then, OS 10.7 UI will prompt user
for NEW username and password.

Notes:
Regression is workable on a case-by-case basis. However, we have
10,000+ mac users and a 90-day password policy that is enforced. With
this current bug, users will have to tinker with their keychain at
least every 90 days.

Please email me at [email protected]<mailto:[email protected]> 
<mailto:[email protected]> or
call at 614-292-9906 to discuss this matter further.
**THIS NEEDS TO BE PRIORITIZED, AS NUMEROUS UNIVERSITIES ARE AFFECTED
BY THIS BUG**

All,

I used the iPhone configuration utility to create a .mobileconfig
file, as recommended by apple. Upon double-clicking, it prompts to
install the profile, and you can optionally enter a username and
password at that time. Either once you enter those and finish profile
installation, or if you skip entering there and later enter username
and password connecting, either way an entry is added to the keychain.
THEN, if the user changes their password, that keychain entry is still
there and is used, continuously failing auth. Only workaround I've
found is to delete the keychain, which results in user prompted for
username and password, at which point a new keychain item is created.

I think this is more of a keychain behavior problem.....or just a WiFi
problem on the Apple. Regardless, the Mac supplicant's behavior should
not try and be stubbornly using wrong credentials over and over. "That
password didn't work?! Hmm. Maybe I should try it again. Didn't work
again? Hmm. Maybe I should try it again. Dang! How about now? no!?
Hmm.... Now?......"

At this point, Xpressconnect is not an option for us. Also, we can't
not do 802.1X. Right now, the only I do I have is bold face text on
the WebUI where users change their password stating that Mac users
*must* delete their keychain, etc.

Additional ideas?

That was going to be my point.  That profile can be for the user or
for the machine.  We are using a user based profile that we modify
via script and "slurp" in to create our connection.  (Cannot say
which id is being used to validate though, have not had time to test
that).

Great question, I was surprised to not see the + in the 802.1X
window.  When I associated to the secure SSID a dialog box popped up
asking for username and password.  I think the credentials are added
to the keychain at that point.

You can also use Lion server to create a profile.  I haven't tested
this but more information can be found here:

In your test machine... How did you create your 802.1x profile?

I did some Lion testing yesterday on our 802.1X secured  SSID and
discovered the following while watching the RADIUS logs:

The laptop had two accounts set up on it, mine and another 'tester'.
If you simply switched users the machine would reauthenticate but
still use the other username/password (the account switching from).

If the laptop was restarted or shut down and started back up the
correct username/password would be used to log into the wireless no
matter what user was logged in when the restart was initiated.

I don't necessarily think this is a big problem in our environment
but I can see where it could be in others.

*Subject:* [WIRELESS-LAN] MacOS Lion & Wireless Password Resets

I have finally got my hands on MacOS 10.7 (lion) and have started
running it through wireless tests. One item I find very worrisome is
this:

- Via WPA2-Enterprise (PEAP/MSCHAPv2), I connect to the SSID using
username & password1; these credentials are then stored in the
keychain

- If I change my password to, say, "password2", then the next time I
connect, the Mac fails authentication

It seems that the Mac, if failing authentication, never prompts for
the username & password to be reentered.

Our university is soon to roll-out and enforce a 90-day password
policy, and I am concerned that users will be unable to authenticate
and forced to remove the password from their keychain.

Have any of you run into this similar issue? If so, how do handle
this behavior? (I don't recall it being this way in MacOS 10.6 or
10.5)
