After a year of pretty much rock solid behavior we’ve had two instances this week where EAP failed for some or all of the users on our WLC 5508 (7.6.130.0). For some users it uses EAP-PEAP-MSChapV2 to a Windows AD server running NPS. For others it uses EAP-TLS to Cisco ACS. Both were experiencing the problem, but the WebAuth SSID worked fine. The ACS logs showed “EAP session timed out.” The Windows NPS logs didn’t show any authentication failures.
After a few hours it fixed itself. I tried a 5508 reboot in one of the instances, and it didn’t appear to help. None of the certs involved have expired and there haven’t been any recent configuration changes. I was going to upgrade to one of Cisco’s suggested WLC software versions over Christmas break—maybe this weekend would be better.
