I have a working configuration of 802.1X authentification on my switch. The radius server is a freeradius instance with EAP-TLS configured. Everything works fine on linux (and android devices), but when I try to hook up a windows 10 pc I'm getting a strange error from the freeradius server:
<...>
Debug: eap_tls: Continuing EAP-TLS
Debug: eap_tls: Peer sent flags --L
Debug: eap_tls: Peer indicated complete TLS record size will be 174 bytes

Debug: Ignoring cbtls_msg call with pseudo content type 256, version 0

ERROR: eap_tls: TLS Alert write:fatal:handshake failure

ERROR: eap_tls: System call (I/O) error (-1)
ERROR: eap_tls: TLS receive handshake failed during operation
ERROR: eap_tls: [eaptls process] = fail
<...>
So, look like no shared cipher
. Now, to the strange part.
TLSv1.2 is used, when the server replies to a client-hello message, it picks a single cipher suite and other variable configuration parameters. When a linux system is connecting, these parameters are: TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384
, null
compression, ECDHE
curve secp384r1
, signature algorithm SHA512+ECDSA
.
The interesting part is that this configuration is offered/supported by the windows system (in client-hello
), but the radius server fails with no shared cipher
. Only difference between these hellos are tls extensions: ocsp stampling, session tickets, extended master secret and renegotiation (all from the windows system, see below).
Is this possible that some of these extensions causes the freeradius (and openssl) replying with no shared cipher
?
Here is the client-hello
packet from the windows system. Right after this packet the NAS replies with failure.
