EAP fails on TLS protocol version with Windows 7, works fine with Windows 10

I have a setup with a Windows 7 and Windows 10 computer authenticating with FreeRADIUS 3.0.20 running on Ubuntu 20.04. The Windows 7 client fails due to a TLS protocol version error: (2) eap_peap: TLS_accept: before SSL initialization (2) eap_peap: <<< recv TLS 1.3 [length 0062] (2) eap_peap: >>> send TLS 1.0 Alert [length 0002], fatal protocol_version (2) eap_peap: ERROR: TLS Alert write:fatal:protocol version tls: TLS_accept: Error in error (2) eap_peap: ERROR: Failed in __FUNCTION__ (SSL_read): error:14209102:SSL routines:tls_early_post_process_client_hello:unsupported protocol (2) eap_peap: ERROR: System call (I/O) error (-1) (2) eap_peap: ERROR: TLS receive handshake failed during operation (2) eap_peap: ERROR: [eaptls process] = fail (2) eap: ERROR: Failed continuing EAP PEAP (25) session.

The problem does not seem to be in the lack of TLS 1.3 support in FreeRADIUS/OpenSSL1.1.1f, because the Win10 client works fine. It starts by asking for TLS 1.3, but gets set to TLS 1.2 and works. I seems my standard Windows 7 client (fully up to date) sends a bad TLS message, but I have no clue where to look for a solution.

Hi Alan, Thanks for your comments. >Define "downloaded". >Did you add that CA to the WiFi profile for the SSID? I am creating a passpoint.config file for android devices and adding trust root CA certificate to profile. So yes Wifi profile has CA. I am using GlobalSign Trusted Root certificate both on android clients and freeradius. On freeradies what i did in tls config : tls-config tls-common { ca_file = /etc/freeradius/3.0/certs/trustrootg2.pem } "trustrootg2.pem" is the certificate which i said GlobalSign Trusted Root certificate. Also when i try with an ios device ,it does not give a CA error, but still dont Proxy to my home Radius. Here is the ios log : Received Access-Request Id 228 from 213.74.143.148:49579 to 10.0.0.4:1812 length 311 (2) User-Name = "iosuser2(a)nevotek.com" (2) Chargeable-User-Identity = 0x00 (2) Operator-Name = "1nevotek.com" (2) Location-Capable = Civic-Location (2) Calling-Station-Id = "74-8d-08-b1-f2-17" (2) Called-Station-Id = "58-f3-9c-43-52-a0:Nevotek" (2) NAS-Port = 4 (2) Cisco-AVPair = "audit-session-id=0a0102e1000001495fbd0ab0" (2) Acct-Session-Id = "5fbd0ab0/74:8d:08:b1:f2:17/395" (2) NAS-IP-Address = 10.1.2.225 (2) NAS-Identifier = "aa5a6c45-b2c2-436b-90da-0ed2031" (2) Airespace-Wlan-Id = 7 (2) Service-Type = Framed-User (2) Framed-MTU = 1300 (2) NAS-Port-Type = Wireless-802.11 (2) EAP-Message = 0x020300061500 (2) State = 0xc1d738d9c0d42d379f86d1a140b85bf5 (2) Message-Authenticator = 0xb6eaf292518a6a1b0412bcf447a369fa (2) session-state: No cached attributes (2) # Executing section authorize from file /etc/freeradius/3.0/sites-enabled/default (2) authorize { (2) policy filter_username { (2) if (&User-Name) { (2) if (&User-Name) -> TRUE (2) if (&User-Name) { (2) if (&User-Name =~ / /) { (2) if (&User-Name =~ / /) -> FALSE (2) if (&User-Name =~ /@[^@]*@/ ) { (2) if (&User-Name =~ /@[^@]*@/ ) -> FALSE (2) if (&User-Name =~ /\.\./ ) { (2) if (&User-Name =~ /\.\./ ) -> FALSE (2) if ((&User-Name =~ /@/) && (&User-Name !~ /(a)(.+)\.(.+)$/)) { (2) if ((&User-Name =~ /@/) && (&User-Name !~ /(a)(.+)\.(.+)$/)) -> FALSE (2) if (&User-Name =~ /\.$/) { (2) if (&User-Name =~ /\.$/) -> FALSE (2) if (&User-Name =~ /(a)\./) { (2) if (&User-Name =~ /(a)\./) -> FALSE (2) } # if (&User-Name) = notfound (2) } # policy filter_username = notfound (2) [preprocess] = ok (2) [chap] = noop (2) [mschap] = noop (2) [digest] = noop (2) eap: Peer sent EAP Response (code 2) ID 3 length 6 (2) eap: Continuing tunnel setup (2) [eap] = ok (2) } # authorize = ok (2) Found Auth-Type = eap (2) # Executing group from file /etc/freeradius/3.0/sites-enabled/default (2) authenticate { (2) eap: Expiring EAP session with state 0xc1d738d9c0d42d37 (2) eap: Finished EAP session with state 0xc1d738d9c0d42d37 (2) eap: Previous EAP request found for state 0xc1d738d9c0d42d37, released from the list (2) eap: Peer sent packet with method EAP TTLS (21) (2) eap: Calling submodule eap_ttls to process data (2) eap_ttls: Authenticate (2) eap_ttls: Continuing EAP-TLS (2) eap_ttls: Peer ACKed our handshake fragment (2) eap_ttls: [eaptls verify] = request (2) eap_ttls: [eaptls process] = handled (2) eap: Sending EAP Request (code 1) ID 4 length 336 (2) eap: EAP session adding &reply:State = 0xc1d738d9c3d32d37 (2) [eap] = handled (2) } # authenticate = handled (2) Using Post-Auth-Type Challenge (2) # Executing group from file /etc/freeradius/3.0/sites-enabled/default (2) Challenge { ... } # empty sub-section is ignored (2) Sent Access-Challenge Id 228 from 10.0.0.4:1812 to 213.74.143.148:49579 length 0 (2) EAP-Message = 0x01040150158000000528dea40bf695dd65cb94e7c64b46f8258e37d115bb5f05ad0b211b1baa131094fc84322e71cb87edc23a19c828d577c87f25ecca323b3e2dcc510401010075eb53b211d878436e2ddb265dee9684eb997a14467b69e48677af7b3f42eae785a2d3a56a072120c33db568484a78c4 (2) Message-Authenticator = 0x00000000000000000000000000000000 (2) State = 0xc1d738d9c3d32d379f86d1a140b85bf5 (2) Finished request Thank you so much.

Hi Alan, Thanks for reply. >The Android device wasn't configured with the CA used by FreeRADIUS. So... add the CA to the android system, and configure it to use that CA when authenticating to FreeRADIUS. I created freeradius CA certificate according to https://wiki.freeradius.org/config/Certificates link. Then eap config for using new created ca.pem Also i downloaded ca.pem file to my Android device but still getting same error. eap_ttls: ERROR: TLS Alert read:fatal:unknown CA I dont understand what you mean with "use that CA when authenticating to FreeRADIUS". What i read in EAP-TTLS, auth server sends the certificate and client validates for open a secure tunnel. Why client have to sent the certificate ? Regards.

Proxy to realm after EAP auth

Hello, I desperately need your help. I am noob with FreeRadius so please guide me what i am doing wrong. My point is using freeradius as a Proxy. Because we already have a PAP supported Radius, so i want to do eap auth part on freeradius and then Proxy the Access-request to our own Radius. We are trying 802.1x authantication. According to my readings i did below steps : 1 . Edit clients.conf for my mobile devices to Access freeradius client nevotek { ipaddr = 213.74.143.140 secret = testing1234 } 2. add home_server in proxy.conf home_server IAS { ipaddr = 192.168.0.252<tel:+11921680252> port = 1812 type = "auth" secret = "secret" response_window = 20 max_outstanding = 65536 } home_server_pool jack_pool { type = fail-over home_server = IAS } realm nevotek { auth_pool = jack_pool nostirp } 3. edit eap.cof default_eap_type = ttls and in ttls function : ttls { default_eap_type = md5 copy_request_to_tunnel = no use_tunneled_reply = yes proxy_tunneled_request_as_eap = no virtual_server = "proxy-inner-tunnel" } 4. prepare Proxy.config soft link for sites-enabled, added nevotek in proxy-inner-tunnel: server proxy-inner-tunnel { authorize { update control { Proxy-To-Realm := "nevotek" } } authenticate { eap } post-proxy { eap } } 5. disabled "suffix" part in sites-enabled/default But no chance. Also android and IOS devices has different behaviors. Here is the output of IOS device : (2) Received Access-Request Id 216 from 213.74.143.148:19733 to 10.0.0.4:1812 length 311 (2) User-Name = "iosuser2(a)nevotek.com<mailto:iosuser2@nevotek.com>" (2) Chargeable-User-Identity = 0x00 (2) Operator-Name = "1nevotek.com<http://1nevotek.com/>" (2) Location-Capable = Civic-Location (2) Calling-Station-Id = "74-8d-08-b1-f2-17" (2) Called-Station-Id = "58-f3-9c-43-52-a0:Nevotek" (2) NAS-Port = 4 (2) Cisco-AVPair = "audit-session-id=0a0102e1000001205<tel:+11000001205>fbba08c" (2) Acct-Session-Id = "5fbba08c/74:8d:08:b1:f2:17/352" (2) NAS-IP-Address = 10.1.2.225 (2) NAS-Identifier = "aa5a6c45-b2c2-436b-90da-0ed2031" (2) Airespace-Wlan-Id = 7 (2) Service-Type = Framed-User (2) Framed-MTU = 1300 (2) NAS-Port-Type = Wireless-802.11 (2) EAP-Message = 0x020300061500 (2) State = 0xca8e79cacb8d6ce3fd1d37ee8f32d170 (2) Message-Authenticator = 0xc7b01c5b471b2eb70578f1dc7ed6e7ea (2) session-state: No cached attributes (2) #

Proxy to realm after eap-ttls authantication
by Mesut Ozturk 23 Nov '20

23 Nov '20

Hello, I desperately need your help. I am noob with FreeRadius so please guide me what i am doing wrong. My point is using freeradius as a Proxy. Because we already have a PAP supported Radius, so i want to do eap auth part on freeradius and then Proxy the Access-request to our own Radius. We are trying 802.1x authantication. According to my readings i did below steps : 1 . Edit clients.conf for my mobile devices to Access freeradius client nevotek { ipaddr = 213.74.143.140 secret = testing1234 } 2. add home_server in proxy.conf home_server IAS { ipaddr = 192.168.0.252 port = 1812 type = "auth" secret = "secret" response_window = 20 max_outstanding = 65536 } home_server_pool jack_pool { type = fail-over home_server = IAS } realm nevotek { auth_pool = jack_pool nostirp } 3. edit eap.cof default_eap_type = ttls and in ttls function : ttls { default_eap_type = md5 copy_request_to_tunnel = no use_tunneled_reply = yes proxy_tunneled_request_as_eap = no virtual_server = "proxy-inner-tunnel" } 4. prepare Proxy.config soft link for sites-enabled, added nevotek in proxy-inner-tunnel: server proxy-inner-tunnel { authorize { update control { Proxy-To-Realm := "nevotek" } } authenticate { eap } post-proxy { eap } } 5. disabled "suffix" part in sites-enabled/default But no chance. Also android and IOS devices has different behaviors. Here is the output of IOS device : (2) Received Access-Request Id 216 from 213.74.143.148:19733 to 10.0.0.4:1812 length 311 (2) User-Name = "iosuser2(a)nevotek.com" (2) Chargeable-User-Identity = 0x00 (2) Operator-Name = "1nevotek.com" (2) Location-Capable = Civic-Location (2) Calling-Station-Id = "74-8d-08-b1-f2-17" (2) Called-Station-Id = "58-f3-9c-43-52-a0:Nevotek" (2) NAS-Port = 4 (2) Cisco-AVPair = "audit-session-id=0a0102e1000001205fbba08c" (2) Acct-Session-Id = "5fbba08c/74:8d:08:b1:f2:17/352" (2) NAS-IP-Address = 10.1.2.225 (2) NAS-Identifier = "aa5a6c45-b2c2-436b-90da-0ed2031" (2) Airespace-Wlan-Id = 7 (2) Service-Type = Framed-User (2) Framed-MTU = 1300 (2) NAS-Port-Type = Wireless-802.11 (2) EAP-Message = 0x020300061500 (2) State = 0xca8e79cacb8d6ce3fd1d37ee8f32d170 (2) Message-Authenticator = 0xc7b01c5b471b2eb70578f1dc7ed6e7ea (2) session-state: No cached attributes (2) #

Proxy to realm after eap-ttls authantication
by Mesut Ozturk 23 Nov '20

23 Nov '20

Hello, I desperately need your help. I am noob with FreeRadius so please guide me what i am doing wrong. My point is using freeradius as a Proxy. Because we already have a PAP supported Radius, so i want to do eap auth part on freeradius and then Proxy the Access-request to our own Radius. We are trying 802.1x authantication. According to my readings i did below steps : 1 . Edit clients.conf for my mobile devices to Access freeradius client nevotek { ipaddr = 213.74.143.140 secret = testing1234 } 2. add home_server in proxy.conf home_server IAS { ipaddr = 192.168.0.252 port = 1812 type = "auth" secret = "secret" response_window = 20 max_outstanding = 65536 } home_server_pool jack_pool { type = fail-over home_server = IAS } realm nevotek { auth_pool = jack_pool nostirp } 3. edit eap.cof default_eap_type = ttls and in ttls function : ttls { default_eap_type = md5 copy_request_to_tunnel = no use_tunneled_reply = yes proxy_tunneled_request_as_eap = no virtual_server = "proxy-inner-tunnel" } 4. prepare Proxy.config soft link for sites-enabled, added nevotek in proxy-inner-tunnel: server proxy-inner-tunnel { authorize { update control { Proxy-To-Realm := "nevotek" } } authenticate { eap } post-proxy { eap } } 5. disabled "suffix" part in sites-enabled/default But no chance. Also android and IOS devices has different behaviors. Here is the output of IOS device : (2) Received Access-Request Id 216 from 213.74.143.148:19733 to 10.0.0.4:1812 length 311 (2) User-Name = "iosuser2(a)nevotek.com<mailto:iosuser2@nevotek.com>" (2) Chargeable-User-Identity = 0x00 (2) Operator-Name = "1nevotek.com" (2) Location-Capable = Civic-Location (2) Calling-Station-Id = "74-8d-08-b1-f2-17" (2) Called-Station-Id = "58-f3-9c-43-52-a0:Nevotek" (2) NAS-Port = 4 (2) Cisco-AVPair = "audit-session-id=0a0102e1000001205fbba08c" (2) Acct-Session-Id = "5fbba08c/74:8d:08:b1:f2:17/352" (2) NAS-IP-Address = 10.1.2.225 (2) NAS-Identifier = "aa5a6c45-b2c2-436b-90da-0ed2031" (2) Airespace-Wlan-Id = 7 (2) Service-Type = Framed-User (2) Framed-MTU = 1300 (2) NAS-Port-Type = Wireless-802.11 (2) EAP-Message = 0x020300061500 (2) State = 0xca8e79cacb8d6ce3fd1d37ee8f32d170 (2) Message-Authenticator = 0xc7b01c5b471b2eb70578f1dc7ed6e7ea (2) session-state: No cached attributes (2) #

Proxy to realm after eap-ttls authantication
by Mesut Ozturk 23 Nov '20

23 Nov '20

Hello, I desperately need your help. I am noob with FreeRadius so please guide me what i am doing wrong. My point is using freeradius as a Proxy. Because we already have a PAP supported Radius, so i want to do eap auth part on freeradius and then Proxy the Access-request to our own Radius. We are trying 802.1x authantication. According to my readings i did below steps : 1 . Edit clients.conf for my mobile devices to Access freeradius client nevotek { ipaddr = 213.74.143.140 secret = testing1234 } 2. add home_server in proxy.conf home_server IAS { ipaddr = 192.168.0.252 port = 1812 type = "auth" secret = "secret" response_window = 20 max_outstanding = 65536 } home_server_pool jack_pool { type = fail-over home_server = IAS } realm nevotek { auth_pool = jack_pool nostirp } 3. edit eap.cof default_eap_type = ttls and in ttls function : ttls { default_eap_type = md5 copy_request_to_tunnel = no use_tunneled_reply = yes proxy_tunneled_request_as_eap = no virtual_server = "proxy-inner-tunnel" } 4. prepare Proxy.config soft link for sites-enabled, added nevotek in proxy-inner-tunnel: server proxy-inner-tunnel { authorize { update control { Proxy-To-Realm := "nevotek" } } authenticate { eap } post-proxy { eap } } 5. disabled "suffix" part in sites-enabled/default But no chance. Also android and IOS devices has different behaviors. Here is the output of IOS device : (2) Received Access-Request Id 216 from 213.74.143.148:19733 to 10.0.0.4:1812 length 311 (2) User-Name = "iosuser2(a)nevotek.com" (2) Chargeable-User-Identity = 0x00 (2) Operator-Name = "1nevotek.com" (2) Location-Capable = Civic-Location (2) Calling-Station-Id = "74-8d-08-b1-f2-17" (2) Called-Station-Id = "58-f3-9c-43-52-a0:Nevotek" (2) NAS-Port = 4 (2) Cisco-AVPair = "audit-session-id=0a0102e1000001205fbba08c" (2) Acct-Session-Id = "5fbba08c/74:8d:08:b1:f2:17/352" (2) NAS-IP-Address = 10.1.2.225 (2) NAS-Identifier = "aa5a6c45-b2c2-436b-90da-0ed2031" (2) Airespace-Wlan-Id = 7 (2) Service-Type = Framed-User (2) Framed-MTU = 1300 (2) NAS-Port-Type = Wireless-802.11 (2) EAP-Message = 0x020300061500 (2) State = 0xca8e79cacb8d6ce3fd1d37ee8f32d170 (2) Message-Authenticator = 0xc7b01c5b471b2eb70578f1dc7ed6e7ea (2) session-state: No cached attributes (2) #

Proxy to realm after eap-ttls authantication
by Mesut Ozturk 23 Nov '20

23 Nov '20

Hello, I desperately need your help. I am noob with FreeRadius so please guide me what i am doing wrong. My point is using freeradius as a Proxy. Because we already have a PAP supported Radius, so i want to do eap auth part on freeradius and then Proxy the Access-request to our own Radius. We are trying 802.1x authantication. According to my readings i did below steps : 1 . Edit clients.conf for my mobile devices to Access freeradius client nevotek { ipaddr = 213.74.143.140 secret = testing1234 } 2. add home_server in proxy.conf home_server IAS { ipaddr = 192.168.0.252 port = 1812 type = "auth" secret = "secret" response_window = 20 max_outstanding = 65536 } home_server_pool jack_pool { type = fail-over home_server = IAS } realm nevotek { auth_pool = jack_pool nostirp } 3. edit eap.cof default_eap_type = ttls and in ttls function : ttls { default_eap_type = md5 copy_request_to_tunnel = no use_tunneled_reply = yes proxy_tunneled_request_as_eap = no virtual_server = "proxy-inner-tunnel" } 4. prepare Proxy.config soft link for sites-enabled, added nevotek in proxy-inner-tunnel: server proxy-inner-tunnel { authorize { update control { Proxy-To-Realm := "nevotek" } } authenticate { eap } post-proxy { eap } } 5. disabled "suffix" part in sites-enabled/default But no chance. Also android and IOS devices has different behaviors. Here is the output of IOS device : (2) Received Access-Request Id 216 from 213.74.143.148:19733 to 10.0.0.4:1812 length 311 (2) User-Name = "iosuser2(a)nevotek.com<mailto:iosuser2@nevotek.com>" (2) Chargeable-User-Identity = 0x00 (2) Operator-Name = "1nevotek.com" (2) Location-Capable = Civic-Location (2) Calling-Station-Id = "74-8d-08-b1-f2-17" (2) Called-Station-Id = "58-f3-9c-43-52-a0:Nevotek" (2) NAS-Port = 4 (2) Cisco-AVPair = "audit-session-id=0a0102e1000001205fbba08c" (2) Acct-Session-Id = "5fbba08c/74:8d:08:b1:f2:17/352" (2) NAS-IP-Address = 10.1.2.225 (2) NAS-Identifier = "aa5a6c45-b2c2-436b-90da-0ed2031" (2) Airespace-Wlan-Id = 7 (2) Service-Type = Framed-User (2) Framed-MTU = 1300 (2) NAS-Port-Type = Wireless-802.11 (2) EAP-Message = 0x020300061500 (2) State = 0xca8e79cacb8d6ce3fd1d37ee8f32d170 (2) Message-Authenticator = 0xc7b01c5b471b2eb70578f1dc7ed6e7ea (2) session-state: No cached attributes (2) #
