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

Monitor the number of open EAP sessions
by Sergey Marochkin 23 Nov '23

23 Nov '23

Hi everyone! I am facing a problem when freeradius reports that the limit of open sessions has been reached. These are log entries, like "Too many open sessions. Try increasing "max_sessions" in the EAP module configuration". During the debugging, it was determined that some ios devices (ipad/iphone), for a reason unknown to me, cyclically cannot complete eap/tls authentication process. I found that these devices successfully start communicating with the NAS (send EAP-Response/Identity). But after receiving the (TLS Start)-message, they no longer send the (TLS client_hello)-message, and restart the association process with the access point and therefore open a new EAP session. If recreate a wifi connection on such a device, it will connect successfully. Until I find the root cause of this behavior, I would like to monitor the number of open sessions of the radius server. But I couldn't find a suitable way to do it. Here is what I tried: - use the "status server" tool, but there is no suitable one among its counters - use tool "control-socket" and radmin but also i didn't find suitable counter Can you help me with this question? Thanks!

IKEv2 VPN clients and 2FA
by Markus Winkler 22 Mar '23

22 Mar '23

Hi all, I hope I may ask you regarding this topic. I have a test setup of OPNsense firewall, FreeRADIUS 3.2.0 and using Linux, Mac and especially Windows 10 (with the native Windows client) IKEv2 VPN clients. OPNsense / Phase 1 is configured to use EAP-RADIUS (i.e. FreeRADIUS) which is authenticating the VPN users against Active Directory. The VPN clients are using IKEv2 and EAP-MSCHAPv2 with (AD-) username and password. I use winbind for authentication (https://wiki.freeradius.org/guide/Active-Directory-direct-via-winbind) and do an additional check if the user is member of a special AD group (via LDAP). These are the key points. And so far it's working fine. But: I have the demand to use 2FA (especially OTP) to increase the security of the VPN access. And that's my very question: I searched around, read tons of articles etc. if that's possible and if yes, what would be the best way to achive this goal. Among others I found this: https://wiki.freeradius.org/guide/2FA-Active-Directory-plus-Proxy and would like to ask if someone has such an environment with Windows 10 clients and used it with e.g. privacyIDEA, OpenOTP or similar systems (other than the mentioned Gemalto Safenet Authentication Services)? It would be the best if the OTP system is running on-prem. Could this work and is it worth the effort to setup such a system? Any feedback is highly appreciated. Thank you and best regards, Markus

RADIUS failing to start correctly when remote DB is unavailable.
by Sea Gull 31 Jan '23

31 Jan '23

Hi, Good afternoon! I have a setup where RADIUS is set to write to multiple DBs simultaneously. I have set this as follows: 1. Copied the SQL instance in /etc/raddb/mods-enabled/sql and had it renamed and configured accordingly. 2. Called them both 3. In the pool, I have set start=0 4. Set read_client to no Although from debug these seem to be correctly set, I am still getting the message that RADIUS is trying to connect to the DB when it is unavailable. After quite a number of minutes and 3 retries, RADIUS fails to start. I have attached the full debug and included some explanation too along the way. Thanks in advance. Kind Regards, SG

certificate expired with PEAP/MSCHAPv2/Android 11 in WiFi
by Olivier 20 Dec '22

20 Dec '22

Hello, For some times now, Android 11 requires cert validation in WiFi connections (see [1]). At the same time, Android 11 also makes it much harder for end users to import self-signed root CA (see [2]). As I provide WiFi connectivity in BYOD environments and can't help end users when they import certs, I choosed to test PEAP/MSCHAPv2 with LetsEncrypt certs though I know this would be less secure than with self-signed root CA. I'm planning to generate and renew LetsEncrypt cert on a remote Internet-connected host, and then copy both privkey.pem and fullchain.pem files to Freeradius instance, as suggested by [3]. In my lab setup, I'm using a Samsung Galaxy Tab A7 Lite to test. Though being Android 11-powered, this device also allows Do-Not-Validate pre-Android 11 option ! When I connect to WiFi with this device, I'm using the following settings: Identity: bar Password: whateverneeded CA Certificate: use system certificate Online cert status: do not validate Domain: the exact CN value My lab setup includes: - a Freeradius 3.0.21 on Debian Bullseye - a Unifi WiFi Network 6.5.55 with WiFi AP - a Samsung Galaxy Tab A7 Lite - valid LetsEncrypt certs My certs files are copied into Freeradius host as: #

REST module config options
by James Narey 30 Nov '22

30 Nov '22

Hi, I'm working on an existing FreeRADIUS 3.0.25 implementation, in particular the REST module. The current configuration sets the following config items in the tls block: cacertdir cacertfile verify_cert These don't appear in the default rest config for 3.0.x. The do appear in the NetworkRADIUS wiki, though the first two do not have descriptions. This page's 'Default Config' link goes to the same file - mods-available/rest in the 3.0.x branch. I'm unsure which names to be using and, while the names of the top two are descriptive, it would be helpful to see some documentation before continuing to rely on them. It would also be helpful to know whether there is a reason to use verify_cert vs check_cert, though it is clear at least that these do the same thing. Thank you, Jim.

Autoreload of freeradius configuration files
by Amit Prajapati 30 Nov '22

30 Nov '22

Hi, I am using freeradius 3.0.20 for one of the projects. For my requirement I am using it as a proxy server. I am able to update the required configuration file (client.conf, proxy.conf and site-enabled/default) with the clients, realms and home-server details, to proxy the incoming request to the home server. My query is that for this requirement I need to add/delete the new/old clients in "clients.conf" or add/delete home-server configuration in the "proxy.conf" file. But for every change in these files I have to restart the server in-order for the change to become effective. Is there any way to dynamically read these configuration files ((client.conf, proxy.conf and site-enabled/default)) without restarting the server? I have tried the HUP signal method, but it's reloading only the freeradius modules even when I changed any of these three files. Kindly advise. Thanks & Regards, Amit

Freeradius: Force user to change password on first login
by Cristian Ciobanu 30 Nov '22

30 Nov '22

Hello, I'm running FreeRADIUS for authenticating and assigning IP addresses to users connected to a SSLVPN server (OCserv). As an authentication source for FreeRADIUS I am using an LDAP server. The setup is working fine and users can connect successfully using RADIUS+LDAP authentication and receive an IP address. After I create the user account on the LDAP server I want to force the user to change its assigned password on first login or if the account has already expired and he is trying to connect to VPN. Is this possible to be done using Freeradius ? I did not find any information in the documentation or solution to explain if this can be done or if it is supported when using RADIUS+LDAP authentication Thank you and kind regards,

dhcp as non root: Failed adding ARP entry in DISCOVER
by Hermann.Lauer＠uni-heidelberg.de 30 Nov '22

30 Nov '22

Hello All, while trying to setup dhcp on a local network I get: (38) } # dhcp DHCP-Discover = ok (38) DHCP: Reply will be unicast to your-ip-address (38) Failed adding ARP entry: Failed to add entry in ARP cache: Operation not permitted (1) NO ENCODE! The server (3.2.0) is running on debian testing as user "freeradius", and I did and verified the "setcap cap_net_admin=ei /usr/sbin/freeradius". Which setup is needed in the dhcp server config section? At the moment it is: ipaddr = 0.0.0.0 src_ipaddr = <ip of interface> port = 67 interface = <interface name> broadcast = yes Thanks and greetings Hermann
