TTLS EAP “unsupported protocol” error
by Bill Schoolfield 04 Mar '24

04 Mar '24

Trying to get Cambium 450 equipment to work with TTLS EAP and FreeRadius. Specifically FreeRadius 3.2.1 on Debian 12.5 Following all the information online, I’ve setup radius including creating my own certificates and tested the setup using the eapol_test tool. Results AOK. But tests with the 450 Cambium equipment (20.1 firmware) fail at the ssl handshake with an error message in the log: “unsupported protocol” I was able to get it to work by forcing TLS 1.0 (setting min and max TLS to 1.0 and setting cipher_list to DEFAULT@SECLEVEL=0). Obviously not a good thing to do but it does suggest a TLS version issue. My question to the group is this simply a matter of what Cambium supports (TLS wise) or is it possible I have something wrong on the FreeRadius side?

authenticate cisco nexus 5000 with freeradius
by Majed Zouhairy 29 Feb '24

29 Feb '24

Peace, according to https://community.cisco.com/t5/security-knowledge-base/nexus-integration-fo… the freeradius configuration is as such: DEFAULT Group == cisco-rw, Auth-Type = System Service-Type = NAS-Prompt-User, cisco-avpair := "shell:roles*\"network-admin vdc-admin\"", but it does not mention what section of freeradius to modify, i tried adding all the information to the user, but then free radius wouldn't restart. which means Default group needs to be added to a different section. any help?

logintime replacement
by Stephen Medina 29 Feb '24

29 Feb '24

I noticed that the logintime module is not in v4. Is there a recommended way of replacing it or should it be moved to an "external" module, e.g. rest, python? -Stephen

Change Tag in ERX-Service-Activate
by dave.tomlinson＠bt.com 29 Feb '24

29 Feb '24

Hi, Hoping someone can help. This is using FreeRADIUS 2.2.9. In my RADIUS accept response I need to send the following: ERX-Service-Activate:1 := "HTTP-REDIRECT(SOME-TEXT)" The SOME-TEXT here may differ based on different subscribers but that and the attributes are all configured in a database so I've added this one but RADIUS returns: ERX-Service-Activate:0 := "HTTP-REDIRECT(SOME-TEXT)" i.e the tag is set to 0 rather than 1. I don't have a field in my table for tags as we've never had need for it any before so assuming it just defaults to 0. All use cases I'm going to have are for ERX-Service-Activate to use a tag of 1 and I have no other attributes that use tags. So I'm hoping rather than modifying my database table to add a new tag field and updating the code to use that new tag field that there's a way of just adding a something to the RADIUS config that rewrites the tag from 0 to 1 whenever it sees ERX-Service-Activate:0. Does this sound possible and if so anyone that could help with the config that would be much appreciated. Thanks, Dave

EAP-TLS doesn't work - EAP Failure
by Lucas Guimaraes 29 Feb '24

29 Feb '24

Hi everyone, For a few days, I'm trying to test FreeRADIUS server to see how EAP-TLS authentication works on Wifi through a POC first. So far, I think I could advance pretty well since I didn't know very much about the EAP-TLS authentication method. Basically, what I'm trying to achieve, is to make the employees connect to the Wifi using a certificate that would be installed on their computer in the future. Doing that, the wifi would be better secure using a RADIUS with EAP-TLS auth rather than a commonly used password. The expectation using FreeRADIUS is to see this POC working proporly using the method EAP-TLS but I'm at a certain point where I don't understand why I'm not getting an Access-Accept where should contain the MS-MPPE-Recv-Key and MS-MPPE-Send-Key attributes too. Instead, what I'm understanding is, the server output is kind saying "...Auth-Type sub-section not found. Ignoring...." The result is the same coming from either a Windows 10 Laptop with the certs installed and wpa_supplicant though an eapol_test.conf Here is the debug output from the server with the failure at the end starting by eapol_test.conf but is kind the same result when the laptop tries to connect as well: FreeRADIUS Version 3.0.26 Copyright (C) 1999-2021 The FreeRADIUS server project and contributors There

EAP-TLS and LDAP authorization
by Ted Tec 27 Feb '24

27 Feb '24

Hello, is the following possible in some way in freeradius 3.2? The freeradius is doing only eap-tls auth. If the eap-tls check was successful, I would like to carry out a second check against an LDAP attribute on the computer object. I would like to build an LDAP filter based on the CN in the requesting certificate and have an attribute returned from the computer object in the LDAP directory. If the value is OK, the device is permitted. Does anyone have some tips for me on how to get started and a few basic hints for implementation this, if this is possible without writing an own module (maybe a similar example)? I'm struggeling on how i can get the CN and pass it to the LDAP module. best regards, Ted

Username not stripped in NPS
by Cristian Di Livio 26 Feb '24

26 Feb '24

Hi all, I would like to configure wi-fi authentication with 802.1x with multiple realms and only one NPS (therefore only one active directory domain). For example: - AD domain -> domain.network - realms that can be used -> domain; otherRealm With PEAP traffic, NPS doesn't allow you to manipulate the realm so I can't use find and replace in NPS configuration. So I tried to send the stripped username from freeradius but the realm still arrives in the NPS with realm and it giving me the error that the domain does not exist. Why the realm os sent even though I said to strip the username in the proxy.conf file? Is there alternatively the possibility to do a find and replace in freeradius? For the moment I'm using UPNs on the Windows server but it's a workaround that I wanted to avoid and which takes away the elegance of the authentication process. Thank you in advance.

Freeradius and Android, TLS Internal Error
by Lorenzo Mirabella 23 Feb '24

23 Feb '24

I have configured FreeRADIUS with EAP-TTLS/GTC and I am using valid certificates issued by Let's Encrypt. The certificate is valid for radius.foo.it and I have cert.pem, chain.pem, fullchain.pem, and privkey.pem. I have configured the tls section of the FreeRADIUS eap module as follows: ``` private_key_file = ${certdir}/privkey.pem certificate_file = ${certdir}/fullchain.pem ca_file = ${cadir}/fullchain.pem auto_chain = no ``` When I try to connect to the access point with an older Android device, I have no issues, as it uses the system certificates. Using Linux and specifying the CA Authority as the Let's Encrypt root, I encounter no problems either. However, when using an iPad, I am prompted to accept the certificate (which is the correct one), but it claims it is untrusted despite the Let's Encrypt root being among the trusted CA. With newer versions of Android, you can choose between 3 options: do not verify, request certificate status, and require certificate status. The first two options work (by entering radius.foo.it as the domain), but for security reasons, I would like the third option to work as well. However, I get this error: ``` (13) eap: Peer sent EAP Response (code 2) ID 5 length 13 (13) eap: Continuing tunnel setup (13) [eap] = ok (13) } # authorize = ok (13) Found Auth-Type = eap (13) # Executing group from file /etc/freeradius/sites-enabled/default (13) authenticate { (13) eap: Expiring EAP session with state 0xf0bbd072f4bec5d6 (13) eap: Finished EAP session with state 0xf0bbd072f4bec5d6 (13) eap: Previous EAP request found for state 0xf0bbd072f4bec5d6, released from the list (13) eap: Peer sent packet with method EAP TTLS (21) (13) eap: Calling submodule eap_ttls to process data (13) eap_ttls: Authenticate (13) eap_ttls: (TLS) EAP Done initial handshake (13) eap_ttls: (TLS) recv TLS 1.2 Alert, fatal internal_error (13) eap_ttls: (TLS) The client is informing us that there is a failure inside the TLS protocol exchange.

EAP sub-module failed (13) eap: Sending EAP Failure (code 4) ID 5 length 4 ``` There is definitely something wrong with the configuration, but honestly, I can't figure out what. Any advice? I'm using the official freeradius docker container version 3.2.3. Thank you in advance. P.S. I am 100% sure that the certificate is valid, which can be verified using openssl verify or by creating a virtual host with HTTPS using Apache.
