I'm working on smartcard authentication with Yubikey4 [smartcard].
As far authentication works as intended with one annoying bug I cannot overcome.
User can log in into domain with yubikey, connect to Extreme wifi [identifi] , and authenticate with smartcard certificate. When yubikey is removed and wifi disconnected, another connection is immpossible till windows user logout and login.
XMC shows: "Authentication request became stale, challenge sent, no response received from client"
Any ideas how to fix it ?
