802.1x and password changes


Userlevel 2
I have 802.1x configured on both wireless and wired. I have noticed that if I save my credentials in the supplicant and then change my password I still get on. How is this possible? I have seen this behavior on both Win7 and MAC OS 10.9.2.

I eventually did get prompted after 10-15 minutes on the wired side. Still have not been prompted for wireless in over 30 minutes. I have disconnected and reconnected multiple times.

I'd reproduce this issue with 802.1X PEAP with Microsoft AD/NPS.
As far as I unterstand that is because the AD allows to use the old password for another hour as per the Microsoft support post...

So no wireless issue as you'd see in the NPS log that a new authentication takes place but the NPS accept the old pw.
