I have two different ISE enviroments both using Certificate based machine authentication. One environment uses the Windows Native supplicant the other uses Anyconnect NAM. Both environments get occasional errors upon authentication. For some reason the devices appear to be presenting an identity using "anonymous" and then failing. This happens randomly on several different devices. The same devices will connect properly using the machine certificate as well randomly. So I am a little at a loss since it doesn't happen all the time, the devices will present the proper identity sometimes but not others. Has anyone seen this issue or better yet know how to resolve it?
