MongoDB and v4
by Alan DeKok 05 Mar '26

05 Mar '26

As we're working to finalize v4 (real soon now!) one question which came up is MongDB. The Mongo team is currently looking into creating a fully async API for Mongo. We would need to use this in v4 in order to increase scalability. If we don't have such an API, then the Mongo drivers would be significantly slower than other databases. Their forum as a poll available at: https://feedback.mongodb.com/forums/924286-drivers/suggestions/47080057-asy… If you're interested in using Mongo with FreeRADIUS please vote on that page for their async API.

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

Help with NTLM_AUTH and a Fortigate
by Matthew Beechey 04 Jun '25

04 Jun '25

I've installed Freeradius 3.0 - That was a default with APT-GET - Let me know if manually getting a newer version is essential. I'm using it in front of a Windows Server and a Fortigate Firewall. I have it talking to the server and joined to the domain. I can manually use NTLM_AUTH and it authenticates Windows users like a dream. With DEFAULT Auth-Type = ntlm_auth in files/authorize I can authenticate users with NTRadPing although I cannot without the DEFAULT.... entry. I cannot authenticate users from the radius settings on the Fortigate - They always fail. Looking at logging from Freeradius with -X i see this entry mschap: Found MS-CHAP attributes. Setting 'Auth-Type = mschap' When I do it with NTRadPing with the DEFAULT set to ntlm_auth I get this entry in the logging (0) Found Auth-Type = ntlm_auth So I'm picking something about the request from the Fortigate is setting it to MSCHAP (v1) and with NTRadPing its doing it with ntlm_auth What do I need to do here - disable MSCHAPv1 and if so how - Something else to force MSCHAP to use NTLM_AUTH Essentially I want to use Windows users for Fortinet VPN and next step is going to be adding 2 Factor authentication with Google, Authy or Microsoft - Hoping I can do it as a rolling code so any app will work? Any pointers here or advice would be good if you have some.

Fetching memberOf attribute
by Matvey Teplov 03 Jun '25

03 Jun '25

Hi Guys, I cannot get the ldap module to fetch a memberOf attribute from AD - it is not putting it as a filter parameter in the LDAP search packet. I need this list later to search through for port-authentication phase through the groups in session-state:LDAP-Group[*]'s to identify which ones are present and return a proper VSA. The LDAP configuration is as follows: ldap { server = 'abc.nomios.nl' identity = 'CN=ABC,OU=ABC,DC=nomios,DC=nl' password = '#######' base_dn = 'DC=nomios,DC=nl' user { base_dn = "${..base_dn}" filter = "(sAMAccountName=%{%{Stripped-User-Name}:-%{User-Name}})" scope = 'sub' access_attr = "memberOf" attribute { memberOf := 'session-state:LDAP-Group' } } # group { # base_dn = "${..base_dn}" # membership_attribute = 'memberOf' # } options { chase_referrals = no rebind = yes ldap_debug = 1 timeout = 10 timelimit = 3 net_timeout = 1 idle = 60 } tls { start_tls = no } update { session-state:LDAP-Group := "%{ldap:memberOf}" } } If I run manually ldap_search, then membership shows. Wireshark confirms that there is no attribute request in the ldap search packet present. Any help will be greatly appreciated! Best regards Matvey Teplov +31 62 705 12 73

Re: Freeradius-Users Digest, Vol 241, Issue 34

Hello Alan, I don't know how I missed this but the solution to my problem was very straight forward. Quick recap, we have a FreeRADIUS v3.0.21 configured for EAP-TTLS/PAP with OpenLDAP. I had an issue where if a user miss spelled their username ldap could not find the user and thus didn't return a "known good" for pap, resulting ERROR: No Auth-Type found: rejecting the user via Post-Auth-Type = Reject This message was then logged to radius.log because we use auth = yes in radius.conf for logging (no custom linelogs for us), it made trouble shooting longer than it needed to be. We wanted to log a custom message in the inner-tunnel Post-Auth-Type Reject, if ldap returned notfound. I added the following to our inner-tunnel authorize stanza, turns out I just had to update the &request:Module-Failure-Message with my message. -ldap if (notfound){ update control { &request:Module-Failure-Message := "[ldap] user not found" } } Now I get the custom message when a user tries to login with a wrong username, without any custom linelogs or extra outputs to the radius.log file. Login incorrect ([ldap] user not found): [johndo(a)lab.local] (from client localhost port 0 cli 02-00-00-00-00-01 via TLS tunnel) Thanks for the tip !

> I don't recall that being part of v2. I got some free time yesterday, I looked through our old v2 config. I believe in v2, it was due to our config, which set Auth-Type to ldap, and since it failed to retrieve a non existent user from ldap it would log the ldap failure error. For our new config, we refrained from setting the Auth-Type to ldap as recommended by the documentation. We get no Auth-type found error because there is no Auth-Type found, since ldap can't provide a "known good" to pap. > But it's easy enough to add in unlang: > -ldap { > if (notfound) { > ... add a message here. > } I could not find which attribute/variable to update with my message, since there is no failure in the authorize santza. For now I have made the following linelog. linelog log_ldap_user_notfound { filename = ${logdir}/radius.log permissions = 0640 format = "%t : Login incorrect: (ldap: user %{User-Name} not found) Client-Mac = %{Calling-Station-Id}" } And added the following in the authorize santza after ldap. ldap if (notfound){ log_ldap_user_notfound } But this outputs an extra line in the radius.log since we use the auth = yes radius.conf. If there is better way to do this let know, in the mean time if I find a better solution I will post it to the mailing list.

Cause: We have confirmed that the EVP_DecryptFinal_ex function returns either 1 or 0, but the return value is being checked using a condition that evaluates whether it is less than 0. This leads to a segmentation fault. Resolution: Our investigation revealed that the issue can be avoided by applying the following modification: src/modules/rlm_eap/types/rlm_eap_fast/eap_fast_crypto.c ==================== - if (ret < 0) return -1; + if (ret == 0) return -1; ==================== /早川

FTP Site will be going away
by Alan DeKok 22 May '25

22 May '25

This is advance notice that the FreeRADIUS anonymous FTP service (ftp.freeradius.org) will be discontinued on Thursday 19th June. The same contents will continue to be served over HTTPS on the www.freeradius.org website https://www.freeradius.org/ftp/ <https://www.freeradius.org/ftp> Please ensure that you update any automation that currently uses the FTP service to instead fetch assets from the HTTPS website, which is secure, highly-available and is backed by a CDN.

Can Post-Auth-Type REJECT log LDAP user not found
by thomas 19 May '25

19 May '25

Hello everyone, I have setup up a FreeRADIUS server with EAP-TTLS/PAP and OpenLDAP, the setup works fine. I have a question regarding Post-Auth-Type REJECT, it correctly logs Login incorrect, but the &Module-Failure-Message is ambiguous for our needs when it comes to troubleshooting. I get the following log if a user types their username incorrectly : `Login incorrect (No Auth-Type found: rejecting the user via Post-Auth-Type = Reject): [johndo(a)lab.local] (from client localhost port 0 via TLS tunnel)` Is it possible to log something along the lines of "LDAP user not found" without making custom loglines? I believe this was possible on FreeRADIUS 2.x.x. You can find the debug info below.

Feature request about rlm_rest
by Bino Oetomo 18 May '25

18 May '25

This is not an Issue. It's more to a feature request , specially about rlm_rest. Currently I Always use 'POST' method with JSON body. I did this because my FreeRadius installation need to serve different kind of Radius client, that each client send different set of attribute. For example a single Mikrotik router that act as a VPN server and A Captive portal (they name it "hotspot". Each of it sent different set of attribute. my only concern is that a creating a http backend that handle a post request need to allow XSRF at first and make a second step to validate if request come from allowed host. So I think it'll be great if rlm_rest have an option that use GET method that encode all attributes as query parameters. Thats all My salute to all FreeRadius developers and contributors

aws-nlb “status” virtual-server ⇒ “Failed inserting TCP socket into parent list / max_connections (16)”
by Pavels Veretennikovs 17 May '25

17 May '25

Hello list, WHAT / WHY ---------- I am running FreeRADIUS 3.2.7 (official docker image) behind an AWS Network Load Balancer. The NLB performs a TCP health-check against the "status" virtual-server on port 8000 every 10 seconds. After ±16 probes the server starts logging: Failed inserting TCP socket into parent list. Ignoring new connection due to client max_connections (16) Health checks continue to be successful (because they are just TCP, I assume). SET-UP ------ Can be reproduced on following Dockerfile: FROM freeradius/freeradius-server:3.2.7 RUN cp /etc/freeradius/sites-available/aws-nlb /etc/freeradius/sites-enabled/aws-nlb RUN sed -i 's/192\.0\.2\.1/*/' /etc/freeradius/sites-enabled/aws-nlb EXPOSE 8000/tcp CMD ["-f", "-X"] The only change is wildcard IP on healthcheck server. All other configuration is untouched vanilla 3.2.7.

detail log permissions warning
by BuzzSaw Code 17 May '25

17 May '25

I'm getting this error in the logs when a COA packet is being processed by the coa-relay server: File /var/log/radius/radacct/detail_coa permissions are 0640 (rw-r-----) not 0660 (rw-rw----)) The configuration for that detail log is: detail detail_coa { permissions = 0660 group = ${security.group} filename = ${radacctdir}/detail_coa escape_filenames = no header = "%t" locking = yes } Is that permission setting possibly being affected by the system umask ? It seems to work, but throws that error regardless.

Matching multiple realms in post-proxy with single configuration
by Dominic ＠ Bluewin 12 May '25

12 May '25

Hi guys Short question, which I wasn‘t able to extract out of documentation or the source on github. When I would like to match a single realm configuration in post-proxy for multiple realms like this: @ABC.COM @STUDENT.ABC.COM Do I have to configure each realm exact matching and add the RADIUS attribute configuration multiple times? Or can I use a wildcard? I tested with *ABC.COM and REGEX wildcarding, but that did not work. Or do I have to work with the fall-through option? Thanks and regards Dominic Von meinem iPhone gesendet...

Way to verify RADIUS status-server of proxy server over RadSec / TLS
by Dominic Stalder 09 May '25

09 May '25

Hi guys Recently, we migrated some of our RADIUS proxy servers from RADIUS (UDP) to RadSec (TCP) and I would like to still be able to monitor the upstream proxy servers. When we were still using RADIUS (UDP), I was able to send a status-server RADIUS message to the upstream server directly, like this and report that back to PRTG (our monitoring tool): echo 'Message-Authenticator = 0x00' | radclient -x 1.2.3.4 status secret Now I would like to achieve something similar, after we migrated the proxy server 1.2.3.4 to TLS only. My initial try was to setup something like this: 1. start a local socat listener on port UDP/11812 and tunnel it to socat -v OPENSSL:1.2.3.4:2083,cert=/etc/freeradius/certs/radsec.pem,key=/etc/freeradius/certs/radsec.key,cafile=/etc/freeradius/certs/edupki-root-ca-cert.pem,verify=0 UDP-RECV:11812 2. send a standard RADIUS (UDP) status-server packet to the localhost port UDP/11812: echo 'Message-Authenticator = 0x00' | radclient -x localhost:11812 status radsec -t 1 3. unfortunately, this isn’t straight forward: You’re trying to receive UDP packets on port 11812 and send them via TLS/TCP using socat. That conceptually makes sense — it’s what RADIUS-over-TLS (RadSec) does — but unfortunately, RADIUS over TLS is not just “UDP in TLS over TCP”. RadSec uses a specific framing: each RADIUS packet must be prefixed with a 2-byte length field when encapsulated over TCP/TLS (per RFC 6614). Based on the documentation of radclient, it does not support RadSEC / TLS natively. And no, I don’t know, how to implement it… Does anybody have an idea, how to implement a simple RadSec / TLS status-server test, maybe with a „workaround“ or a detour over the FreeRADIUS configuration? Regards Dominic

freeradius confuses switch
by Christoph Egger 09 May '25

09 May '25

Hello, In tcpdump I see the radius packets in the following order: switch -> freeradius: access-request (1), id: 0x2d freeradius -> switch: access-reject (3), id: 0x2d freeradius -> switch: access-accept (2), id: 0x2c In the last packet the switch receives all proper vlan attributes. In the tplink switch CLI I see it does *not* change the port state from unauthorized to authorized. Upgrading the switch to latest firmware did not change anything. I am not sure is the switch working correctly because of the access-reject package? Regards, Christoph

password not present in ttls inner-tunnel
by Evan Sharp 07 May '25

07 May '25

Hi list, I'm having difficulty understanding why &User-Password is not being found by my inner-tunnel virtual server. Desired outcome is EAP-TTLS/PAP for google's LDAP. New install of freeRADIUS 3.2.7. In my debug output, I see that the conditional check that would specify ldap as the Auth-Type is not passing. [eap setup success] [ttls setup success] ... (5) if (&User-Password && !control:Auth-Type) { (5) if (&User-Password && !control:Auth-Type) -> FALSE (5) } # authorize = updated (5) ERROR: No Auth-Type found: rejecting the user via Post-Auth-Type = Reject (5) Failed to authenticate the user [post-auth-reject] I believe this check is the one in my customized module config "ldap-google" if (&User-Password && !control:Auth-Type) { update { &control:Auth-Type := ldap } Ok, so &User-password isn't found. Why not? The eap config looks like: eap{ default_eap_type = ttls ... ttls { copy_request_to_tunnel = yes virtual_server = "google-ldap" Does copy_request_to_tunnel not put the password into the tunnel as &User-Password ? Thanks, Evan

Inner Tunnel User-Name
by Christoph Egger 07 May '25

07 May '25

Hi, I have configured EAP-TTLS+PAP using sites-enabled/proxy-inner-tunnel. After I get the Access-Accept message, I do dynamic VLAN assignment in sites-enabled/default in the post-auth section. The one thing is: the dynamic VLAN assignment uses the outer User-Name. It works if the outer-tunnel matches the inner-tunnel username. I want to do the dynamic VLAN assignment using the Inner-Tunnel User-Name. Where can I access the inner-tunnel %{request.User-Name} with ulang after the Access-Accept message ? Regards, Christoph

How to Remove Framed-MTU from Access-Accept in PEAP Authentication
by 早川拓人 07 May '25

07 May '25

Hi! I noticed that when performing PEAP authentication using FreeRADIUS, an unintended "Framed-MTU" attribute is included in the Access-Accept. Could you please advise on how to remove this "Framed-MTU" from the Access-Accept? After some investigation, I found that adding the following code at the beginning of the post-auth section allows for its removal: ========================================================================== sites-enabled/default.in<http://default.in/> ----- post-auth { + if ( &session-state:Framed-MTU ) { + update session-state { + &Framed-MTU !* ANY + } + } ========================================================================== Is this method correct? Additionally, is there a simpler and safer way to remove the "Framed-MTU"? Thank you for your assistance. Please find the debug log below for your reference. Due to email size constraints, I have included an excerpt in the email. For the full log, please refer to the attached FreeRadiusv3_2_7_PEAP_Accept.log. ========================================================================== FreeRADIUS Version 3.2.7 Copyright (C) 1999-2023 The FreeRADIUS server project and contributors There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE You may redistribute copies of FreeRADIUS under the terms of the GNU General Public License For more information about these matters, see the file named COPYRIGHT Starting -

Accounting drop when authentication
by Ibrahemoo Ghost 04 May '25

04 May '25

I use FreeRADIUS Version 3.0.20 as both proxy and (auth/acct) server. I have more than 200 realms. Every one of them is redirecting to a different site file with a separate sql module but with a shared sql_pool. I recently had a strange problem, every time the system hits 150 auth requests per second accounting packets drop from 1000 req/s to about 200 req/s and the system begins to delay accounting requests and accounting no response log messages arise in connected clients. The system operates normally under heavy load and no stress is visible to me in the sql server. I am using a monitor system and it shows no drop or increase in sql load. During accounting drop the ssd usage drops from 80% to 20%. My radiusd thread pool configuration for 36 cores and 256GB ram and enterprise ssd is: thread pool { start_servers = 60 max_servers = 144 min_spare_servers = 20 max_spare_servers = 60 max_requests_per_server = 0 auto_limit_acct = no } My shared sql_pool around all 200 sql modules is: pool { start = 36 min = 18 max = 72 spare = 36 uses = 0 retry_delay = 30 lifetime = 0 idle_timeout = 60 } I have already checked and tuned mysql server to best values and checked the indices for the tables and everything is pretty well configured I am 80% sure the problem is with freeradius configuration because what solve the problem temporarily is restarting freeradius service until it rehits 150 auth req/s and problem rearise. Do you agree with me that the problem is from freeradius or it could be something else and what can I do to solve it ? Thanks in advance Ibrahem

Some notes on v4
by Alan DeKok 03 May '25

03 May '25

I've pushed some notes on v4 to github: https://github.com/FreeRADIUS/freeradius-server/blob/eb234d6bd979218367e463… As for updates, we're still working on it. The only remaining feature to re-implement in v4 is RADIUS/TLS. Alan DeKok.
