Dear All,
What radius server are you using?  There has been a bug in FreeRadius server 
prior to 2.1.11 which failed to send back a failure message to the clients.  
After patching we did not experience this problem.  I don't know that we have 
tested on Lion.

I believe there is(was) also a bug in the apple client which causes issues with 
the Microsoft radius server.  It failed to use the correct session sequence and 
the Microsoft radius server discarded the response after failure.  I believe it 
is possible to configure the server to ignore the seqence bug.

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]> 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

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)
