Hi
We are deploying an instant solution on several schools and the teacher's SSID has 802.1x authentication to a remote radius server.
We've been testing using a domain user and non-domain computers, some of the tests work but most of them don't and checking the radius server logs i found that the reason to refuse the authentication is error code 265 which is "The certificate that the user or client computer provided to NPS as proof of identity chains to an enterprise root certification authority that is not trusted by the NPS server". Nonetheless when we do tests with an android phone it works everytime.
We are not using certificates on the server and the clients are configured not to validate them. I'm sure is not a configuration problem in the radius server because i do a similar test in the management center (where the server is) with my non-domain pc (and APs from another brand) and works everytime.
What can i do to diagnose the cause of this problem since we are not using certificates? I upload the reject event to se if there's anything else there i haven't seen.
Thanks.
