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

Memory leak in FR 3.0.19 ?
by Arnaud LAURIOU 30 Jun '20

30 Jun '20

Hi, We are suspecting memory leak in FR 3.0.19 : process memory status show VmData always keep increasing leading to VmSwap use after a few days which also keep increasing. I have 2 questions : - What are the compile options to use valgrind ? only flag --enable-developper ?|| - In the changelog for version 3.0.20 : some memories problems seems to be solved, do you know when this version will be released ? (if the release date is close, we can wait to test this release rather than 3.0.19) Regards, Arnaud Lauriou

How to deal with device self-registration best?
by Nilsson, Cristian (Göteborg) 03 Feb '20

03 Feb '20

Hello everyone! I am quite new to freeradius and apologize if this has been answered before, I have searched - and a lot of it without finding a good answer. Please direct me if this is already answered. I have a setup of Extreme Wing wi-fi controller and want to implement a guest-user system with captive-portal and device registration/recognition in combination with the standard pre-defined users. I have a radius server going and everything is good as long as I have a user created in radius. Now my challenge is that for "device registration" I see in radius debugs a username sent in form of device mac-address (password is empty) and the expected access-reject as this user is not defined. How can I on the fly add non-existing users into radius database (we use mysql) and from there let accounting take over for session limitations etc? Preferably this would also match some sort of criteria, example a specific subnet. I greatly appreciate any help!

Disable logging for one virtual server
by Richard Green 31 Jan '20

31 Jan '20

Is it possible to disable logging for one virtual server, with FreeRADIUS 3? I have a network load balancer in front of FreeRADIUS 3, for the purposes of multiple availability zone fail-overs in AWS. The health checks (which are only valid for TCP btw) are resulting in many logged errors: Wed Jan 29 04:28:24 2020 : Error: Ignoring request to auth proto tcp address * port 1812 bound to server health-check-tcp from unknown client 10.118.241.27 port 43332 proto tcp Thanks Richard ______ Richard Green IT Solution Design & Delivery | UNSW Sydney | NSW 2052

rlm_rest learnings - PAP and PEAP/MSCHAPv2
by Lang, Russell 30 Jan '20

30 Jan '20

Thanks to Arran for his hints on calling a REST API from FreeRADIUS. rlm_rest is working, doing authentication for WPA2-Personal (PAP via captive portal) and WPA2-Enterprise Wi-Fi clients (PEAP/MSCHAPv2). Using FreeRADIUS 3.0.16 (Ubuntu 18.04). PAP is handled in the default site, while the MSCHAP2 part of PEAP/MSCHAP2 is handled in the inner-tunnel. The trick is preventing the REST API from being called in the default site with EAP outer messages, which would result in 9 unwanted API calls. The authorize REST API code does pre-authentication and if it passes it returns the NT-Password or Cleartext-Password as appropriate. To find out if the user was authenticated, a post-auth REST API is used to log success/failure. rest module configuration: authorize { uri = "RADIUS_API_PATH/radius?action=authorize" method = 'post' body = 'json' auth = 'basic' username = 'RADIUS_API_USER' password = 'RADIUS_API_PASSWORD' } post-auth { uri = "RADIUS_API_PATH/radius?action=post-auth&result=%{control:Post-Auth-Type}" # result is either '' or 'Reject' ... } API pseudo code for authorize: if pre-authenticated if mschap return { "control:NT-Password": {"type":"octets","value":[ "0x0123456789ABCDEF0123456789ABCDEF" ]}}, 200 else return { "control:Cleartext-Password": {"type":"string","value":[ "clear-text-password-here" ]}}, 200 else: return {}, 401 default site config: authorize { mschap eap { ok = return } if (!ok && !updated) { # Only call rest if not handled by EAP rest } pap } post-auth { ... if (!&reply:EAP-Message) { # Only call rest if not EAP rest } ... } inner-site config: authorize { mschap eap { ok = return } if (!ok && !updated) { # Only call rest if not already handled rest } pap } post-auth { ... rest ... } Issues: When doing PEAP/MSCHAPv2, the authorize REST API gets called twice in the inner-tunnel, for two different EAP messages. Wastes a few milliseconds, but only a minor issue. Using radtest -t mschap valid-user@domain invalid_password 127.0.0.1 0 radius_secret replied with MS-CHAP-Error = "\000E=691 R=1 C=ad8367a70f809d72 V=2" My reading of the MS-CHAP-V2 RFC2759 and PPP CHAP RFC1994 is that this should have been MS-CHAP-Error = "E=691 R=1 C=ad8367a70f809d72 V=2"

Dealing with Apple Watches?
by Ted Hyde (RSI) 30 Jan '20

30 Jan '20

Howdy - So I'm not an "Apple Guy". I tolerate them, I support them, but I don't own them. I recently redesigned one of our office networks to split up departments into vlans (something that was on my list for a long time and desperately needed), and after some labbing, rolled it out last week. I intentionally kept the wifi out of the main distribution loop because I needed to really find out what levels of security the staff would permit. While I would love to enforce full EAP-TLS (or TTLS) some of that is difficult with transient workers, staff, and of course some devices that don't support certificates. So to wrangle this, I created a dedicated subnet (a little /27) and made it wpa2-psk. Simple test just to keep the bare minimum going. Except after giving two people the pwd, I ran out of scope. This seemed odd, how could two people eat up some 28-odd ip addresses? First thought, they blabbed. Turns out they did tell "only a couple of other people" - which is exactly what I needed to find out in this test - a psk is useless security in the workplace. That still didn't account for everything. So I cleared out all the ip bindings and watched as all the clients re-acquired ip addresses. 28 gone in a heartbeat. There weren't 28 people in the building. Half of these folks were "very-Apple-people". That means iMac, Mac-top, ipad, watch, phone, backup watch, backup phone..... and they all of course (in hindsight it's obvious) use their devices in "Default" mode which means accepting all of Apple's recommendations without reading them. After clearing the scope and changing the password, I went and worked with one user directly, typed in the credential myself on her laptop. While I was holding her phone, I got interrupted, and when my attention went back to the phone, I saw that it had already connected - how did it get the new key? I'm sure at this moment there are 50 admins talking to the screen saying "oh, all Apple users can set their devices to share and automatically connect as a convenience" - an item that I was not aware of prior. I took the test a step further and was able to observe that another user has credentials automatically pop up to his icloud account, wherein his ENTIRE FAMILY gets the credential. Not good. Definitely not good. I'm sure this is happening in school campus scenarios where staff and students eat up scope from devices that shouldn't ever be permitted on a particular network, and since folks like the convenience, they sync their phones to their dtops, and no group policy is going to get in the way of that. Does anyone have a workable solution to controlling this above? Is it "some auth" + Mac Auth? Or is it "give up on control and just make huge networks so there's enough scope"? With decidedly less hair, many thanks, Ted.
