Authenticate to AD but only allow certain group
by Brian C. Huffman 16 Aug '25

16 Aug '25

All, I've got authentication working nicely with MSCHAP, but now I'd like to only allow users that are members of a certain AD group. I would prefer to have this happen only when requests come from a specific client (wireless access point). In this case the idea is to have users only be able to get wireless access when they're in a specific AD group. How can I do this in freeradius? Thanks, Brian

RE: EAP-TLS Signature Check Failure
by nabble＠felix.world 12 Jul '22

12 Jul '22

Hi Together, we finally got the issue and for the anyone else, how will face the issue, the fix is quite simple. Update your TPM Firmware! In fact, during the authentication the client is sending a signature which only includes nulls. The packet itself is intact, sizes of the packets are valid and the signature algorithm is also well. The only thing that's not in the tls authentication is a signature. : ```` (4) eap_tls: <<< recv TLS 1.2 (type: 0016) [length 0108] handshake_type: 0f, alert_level: 00, alert_description: 00 0f000104 TLS handshake certificate_verify len 0x000104 = 260 0804 signature algorithm: rsa_pss_rsae_sha256 0100 signature size: 0x0100 = 256 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 00000000000000000000 000000000000 ```` That's also the reason why some of our clients are able to authenticate and some not, with the key, stored in TPM. Intel ships end customer TPM updater, STM as we know not. We also don't have clients with Infineon chips but they should also ship updates to the end customer. FYI: This was a team operation and thanks to all that helped here. Regards, Lineconnnect <quote author='Users mailing list'> 2 months later, a quick update on this topic (apologies, I may have broken the threading as I don't have a copy of the original e-mails any more!), just so there's an online reference here for anyone encountering the same error. Turns out I was wrong about it being Windows and OpenSSL getting muddled over TLS 1.2 vs. 1.3... To recap: Windows 10 clients, corporate WiFi network using EAP-TLS to RADIUS with machine certificate (SCEP) authentication only.

All is well again, and I'm close to shutting down NPS :-) -- Peter Bance Information Security Adviser Alan DeKok wrote: > A final update on this, in case anyone here's interested (or to "wrap > up" for anyone stumbling across this thread online) - I fixed it, and > Windows clients are now happily joining WiFi.

Initial design question
by Jure Simšič 01 Jul '21

01 Jul '21

Hi, I'm trying to configure radius for an edu organisation that has the following needs: a1. staff wifi (edu employees) a2. eduroam wifi a3. network devices auth for admins a4. eth 802.1X auth in future There are a couple of backends I need to authenticate to: b1. staff is in MS AD - staffAD b2. students have another AD not part of same AD domain, I need to auth them separately - studAD b3. visiting students/lecturers get their auth via eduroam delegation to their home organisations Additionally I have special needs for a3 that apart from the u/p I need to check if they are members of a particular group. I've already set up the basics for b1 via winbind and it seems to be working via radtest. What I've managed to read in the various docs is that I can only authenticate to one AD via AD membership / winbind and also if I want to check group membership it has to be done via LDAP (can do it via ldapsearch). So I have a couple of questions on what is the correct way to set up all this: 1. should I make a separate server instance in sites-available for b1-3 (or even two for b1 if I need to do a separate LDAP auth for a3) and put each one on a separate port? 2. how to deal with eduroam wifi - a user can be from several realms - 1) @edu auth b1, 2) @student.edu auth b2, @anything_else delegate. Where should this actually be done? In a server configuration or in proxy.conf or where? 3. I've already started editing files in mods-available (namely ldap) but it feels wrong to do it there on the master files. Should I make a copy for each LDAP server in mods and reference it somewhere or how do I make separate copies for different backends and ldap filters.. And how&where do I call the correct module for different ldap backends? So am I correct in the assumption that I will need the following servers: 1. one winbind for a1 and a2 @edu realm that authenticate to b1 2. one ldap for a2 for @student.edu to b2 3. one ldap for a3 (and a4) to b1 4. one forwarder/proxy for a2 for @other Thanks a lot for any pointers. I'm starting to get the feeling if I don't do this the proper way from the start I'm going to get entangled in a messy knot rather soon.. Cheers, Jure

ARTICLE: RADIUS design for universities
by Network RADIUS 30 Jun '21

30 Jun '21

** RADIUS design for universities --------------------------------------------- University environments present challenges for RADIUS system design. Every hour, on the hour, thousands of students close their laptops, move to a different location, and open them again. This unique environment requires a unique infrastructure to support it. Every hour, on the hour, thousands of university students need to be authenticated, and their thousands of laptops need to be assigned IP addresses. All of these students must get on the network quickly and efficiently, otherwise the help desk will be flooded with complaints. This process becomes even more challenging when, as is commonly the case, a university has multiple campuses in different locations, but authentication servers are only provisioned at a central location. At Network RADIUS, we have created a standard RADIUS infrastructure for universities and colleges. This infrastructure has been deployed at multiple sites, where it has proven to be both fast, and stable.

proxy.conf (from v2 to v3) - edoroam - NRO - configurations - requested - regarding
by P.Thirunavukkarasu 26 Jun '21

26 Jun '21

Hi all, Greetings. I configured the FreeRADIUS 3 (Centos 7) with G Suite LDAP for our University. I need to configure the eduroam for our University. Our domain name is *tanuvas.org.in <http://tanuvas.org.in/>* Our NRO gave the proxy configuration as follows. As far as I understand, the NRO’s configuration is in FreeRADIUS version 2. We requested the NRO to provide the details of one more server for fail-over. *------------------------------------------------------------------------* *realm tanuvas.org.in <http://tanuvas.org.in/> {* *authhost = LOCAL* *}* *realm DEFAULT {* * authhost= flr1.eduroam.ernet.in <http://flr1.eduroam.ernet.in/>* *secret = <<secret>>* *nostrip* *}* ----------------------------------------------------------------- I wish to configure the above in FreeRADIUS version 3. My configuration of proxy.conf as follows *#Proxy Server Configuration* proxy server { retry_delay = 5 retry_count = 3 default_fallback = no dead_time = 120 wake_all_if_all_dead = no } ------------------------------------------------------------------------------------------------ *#Home Server Configuration* home_server flr1.eduroam.ernet.in { ipaddr = 144.16.140.190 port = 1812 type = "auth" secret = <<< secret >>> response_window = 20.000000 response_timeouts = 1 max_outstanding = 65536 zombie_period = 40 status_check = "status-server" ping_interval = 30 check_interval = 30 check_timeout = 4 num_answers_to_alive = 3 revive_interval = 120 limit { max_connections = 16 max_requests = 0 lifetime = 0 idle_timeout = 0 } coa { irt = 2 mrt = 16 mrc = 5 mrd = 30 } } *------------------------------------------------------------------------------------------* *#Home Server pool Configuration* home_server_pool EDUROAM { type = fail-over home_server = flr1.eduroam.ernet.in } *-----------------------------------------------------------------------------------* *# realm configuration* realm tanuvas.org.in { auth_pool = LOCAL } realm DEFAULT { auth_pool = EDUROAM nostrip } ------------------------------------------------------------------ The questions are, 1. As I understand, the home server means the eduroam servers of NRO. Hence, I configured the home server and home server pool as above. 2. Are the above proxy and realm config correct or not? 3. Our domain name is tanuvas.org.in. I configured the realm as LOCAL 4. Realm DEFAULT points to the Home Server Pool EDUROAM. Is it correct 5. Mention the corrections required in the proxy.conf 6. Is it necessary to configure the realms NULL and LOCAL (We are having two more domains named tanuvas.ac.in and tanuvas.edu.in) Best Regards, *Thirunavukkarasu*

Removing all attributes from a packet for a particular vendor
by paul.moser＠bt.com 25 Jun '21

25 Jun '21

Is it possible to remove all attributes of a specific vendor from a request/reply? I'm currently doing update request { <attribute_name_1> !* ANY <attribute_name_2> !* ANY ... } which works, but does mean I need to make sure I keep my code in sync with any attributes that get added to that vendor. Thanks, Paul

Updating from 2.0 to 3.0 - ERROR: No Auth-Type found
by Alberto Balsalm 25 Jun '21

25 Jun '21

Hello, I recently updated my secondary RADIUS server from 2.X to 3.0.16. I am running Daloradius with MySQL. I am trying to authenticate through SQL via a user / group / NAS setup on DaloRadius, I receive "(0) ERROR: No Auth-Type found: rejecting the user via Post-Auth-Type = Reject" when attempting to authenticate via this secondary server. My primary RADIUS server is still running a 2.X version of FreeRADIUS and runs its own instance of Daloradius and MySQL. This primary server functions fine and I am able to login via SQL authentication. The configurations for FreeRADIUS, DaloRADIUS, and MySQL are essentially mirrored, with changes being made on the secondary's config to accommodate the update to 3.0. Below is my Freeradius -X output for my secondary server.

freeradius server works only on localhost

Hi All, I'm new here. <https://unix.stackexchange.com/posts/655577/timeline> I have a freeradius server setup but it only works on my localhost. I do see the frames from the remote host coming in on Wireshark, so the requests do arrive but on the client I just get: |radtest MAC foo host:1812 0 bar Sent Access-Request Id 67 from 0.0.0.0:47922 to host:1812 length 82 User-Name = "MAC" User-Password = "foo" NAS-IP-Address = 127.0.1.1 NAS-Port = 0 Message-Authenticator = 0x00 Cleartext-Password = "foo" Sent Access-Request Id 67 from 0.0.0.0:47922 to host:1812 length 82 User-Name = "MAC" User-Password = "foo" NAS-IP-Address = 127.0.1.1 NAS-Port = 0 Message-Authenticator = 0x00 Cleartext-Password = "foo" Sent Access-Request Id 67 from 0.0.0.0:47922 to host:1812 length 82 User-Name = "MAC" User-Password = "foo" NAS-IP-Address = 127.0.1.1 NAS-Port = 0 Message-Authenticator = 0x00 Cleartext-Password = "foo" (0) No reply from server for ID 67 socket 3 | While on localhost I get: |radtest MAC foo 127.0.0.1:1812 0 bar Sent Access-Request Id 12 from 0.0.0.0:50005 to 127.0.0.1:1812 length 82 User-Name = "MAC" User-Password = "foo" NAS-IP-Address = 127.0.1.1 NAS-Port = 0 Message-Authenticator = 0x00 Cleartext-Password = "foo" Received Access-Accept Id 12 from 127.0.0.1:1812 to 127.0.0.1:50005 length 20 | How do I open server access up to the outside, as well?

problems with connection pooling
by Alen 22 Jun '21

22 Jun '21

Hello, We have setup a freeradius server (3.0.21) that connects to Pgbouncer/Postgres database. Every time the NAS connects to the freeradius server, 3-4 new connections are opened up in the database until it runs out and stalls. Does Freeradius use some sort of connection pooling? I have a suspicion that could be related to the thread pool as defined below: radiusd.conf: thread pool { start_servers = 5 max_servers = 32 min_spare_servers = 3 max_spare_servers = 10 max_requests_per_server = 0 auto_limit_acct = no } 1) Is there somewhere I can make Freeradius reuse existing connections instead of creating new connections whenever the NAS connects to it? 2) Can the number of connections created by Freeradius be controlled in any config? Thanks, Alen

Question about the architecture
by Alen 22 Jun '21

22 Jun '21

Hello, I'm seeking advice about what the optimal setup is. We have around twenty NAS worldwide that need a central point of monitoring. 1) Should we setup multiple freeradius servers worldwide connecting to a single central database? 2) Or should we setup a single central freeradius server (sitting close to the database) and make all the twenty NAS connect to the central freeradius server instead? Thanks, Alen
