So, "suddenly" we started getting this as an error. The people responsible for making computer images (Windows 10 1703 specifically) have started encountering this error when attempting to perform a user based 802.1X authentication on wireless after a fresh image deployment. Apparently, the device is joined to the AD domain already, the user logs in, then when they attempt to connect to our SSID with username/password 802.1X authentication, it fails. The error message on ClearPass (6.6.8) is "Received failure TLV from client". If the device is changed to perform computer authentication, it succeeds. Once the single successfull authentication happens, any attempt after that to do user based 802.1X also succeeds. It is just the first time "out of the box" that fails. I suspect it is a certificate issue. Something missing, or an attempt to access some offsite address that fails is causing it.
Anyone have any thoughts?
