configuring client certificates
by Home IT 18 Feb '20

Hello Everyone I have a Question if freeradius does support user/client certificate + username and password authentication meanwhile? Here is a conversation from 2017: http://lists.freeradius.org/pipermail/freeradius-users/2017-September/08891… I try to configure a VPN with IKEv2: https://forum.netgate.com/topic/150554/ikev2-certificate-eap-username-passw… Which i think is not supported? I hope someone who understands more than me could confirm. Many thanks Regards Alitai

IP pools with rlm_sql_mongo + some general testing with MongoDB
by Benjamin Thompson 17 Feb '20

17 Feb '20

Firstly, many thanks to all concerned for creatiing a MongoDB module. I have been doing a bit of testing of IP address allocation from pools in MongoDB and I wanted to share some thoughts and notes (in no particular order) in case they are useful: 1) I noticed that rlm_sql_mongo expects any returned data to be in a field called "value". This means that for example for a document which defines an IP address entry in the pool the actual IP must be stored in the "value" field instead of something like "framed_ip_address": { pool_key: "foo" pool_name: "bar" expiry_time: xxx value: "192.168.1.1" } I don't see any problem with this, but I mention it in case it is useful to anyone else who tests the module. 2) MongoDB requests generally use a lot of curly brackets so when callied via %{sql: xx} it is necessary to escape them with an extra percent symbol. So in the actual request any "}" should be replaced with "%}". This also maybe useful info to anyone testing for the first time. 3) In my case I wanted to implement an IP pool with "sticky addresses" based on a unique PPP username. One point to note is that the method findAndModify() does not support sorting by an exact value. So for example it cannot simulate something like "ORDER BY foo <> bar" which is possible with other databases. In my case I decided to work around this using two seperate requests: the first one does a lookup by exact string to see if we can allocate the same IP, then if this does not return anything do a second lookup and sort by expiry_time to find the oldest free IP. Due to this I implemented all the database requests directly in unlang directly in the authorize section instead of using the sqlippool module. 4) I did at one point test the sqlippool module with a variation of the above logic by calling one request in allocate_clear and another in allocate_find. However for some reason I noticed that allocate_clear was not geting called every time and somehow the server was skipping it and calling allocate_find immediately. It could have been a problem with my configuration so I will try to repocude the problem if I get time. 5) In general I am very pleased with the performance. For a pool database with 20000 entries on a modest 6 core virtual machine I reached 6000 requests per second with radperf. -- Ben Thompson

Installation and paths
by RJ Jafarkhani 15 Feb '20

Hello FreeRADIUS gurus! I’m installing on Amazon Linux (centos) and hit a couple of snags I’m hoping you could help me with. The yum install (3.0.18) doesn’t pull in any of the mods-config, specifically the mysql (sql) support I’m looking for (maybe I’m missing something?). So I’m trying to build it (3.0.20), follow the posted instructions (configure, make, etc), but wasn’t sure if it’s completing successfully. Mysql is installed and I don’t get any warnings for it when configuring (haven’t configured the sql connection yet). Some questions: 1. How can I tell if the install is successful? I get the below at the end of the configure: configure: creating ./config.status config.status: creating all.mk 1. It seems to run from where I set it up (./buid/radiusd). Do I need to move it to a specific path? If so, where does it go? Looks like the confs were placed in /usr/local/etc/raddb 1. Is the mysql schema the same for all 3.0.xx versions? I’m not a sysadmin, but know a little to be dangerous and I want to learn. So your help is greatly appreciated! -RJ In case it helps: When I run radiusd -X from the original untar location (./buid/radiusd), I get: FreeRADIUS Version 3.0.20 Copyright (C) 1999-2019 The

proxying and unlang
by Matt Zagrabelny 14 Feb '20

14 Feb '20

Greetings, I have a FR system that performs local auth and then does some extra policy checks (unlang) in post-auth. I am looking to proxy all my auth to a remote system (not FR), but I'd still like to sanity check if the remote system does not reject the auth. Do folks put policy unlang into post-proxy? I see from the docs: "Once the post-proxy section has finished executing, any existing attributes in the reply list are discarded, and the post-proxy attributes are copied to the reply list. This behavior allows a home server to define the default reply sent back to the NAS." that the local attributes are discarded. Is there a way to update the reply in post-proxy? For instance, this is a snippet of my current post-auth: post-auth { if (User-Name == "foo") { update reply { Reply-Message := "bar" } reject } } Thanks for any hints! -m

Listening on proxy address * XXXXXX
by Sezer BAGLAN 14 Feb '20

14 Feb '20

Hi all, When I run freeradius with basic configuration in debug mode I see that freeradius server listens an arbitrary port other than 1812 and 18120. Necessary debug prints are as given below: -------- Listening on auth address 10.0.2.15 port 1812 bound to server default Listening on auth address 127.0.0.1 port 18120 bound to server inner-tunnel *Listening on proxy address * port* *35629* *--------* Why freeradius server listens such an arbitrary port? Is it possible to configure it? Kind regards, Sezer

Re: 2FA Challenge via Proxy Realm with valid State

Thanks Alan, Your advise was spot on. I moved/added the ldap.authenticate so that both steps use the Proxy-To-Realm and this meant the correct Access-Challenge response is sent during the first step. if (!State) { if (&User-Password) { # If !State and User-Password (PAP), then force LDAP: update control { Ldap-UserDN := "%{User-Name}(a)my-domain.com" Auth-Type := LDAP } ldap.authenticate if (!ok) { reject } } else { reject } } update control { Proxy-To-Realm := "proxy-test" } I kept 2 rejects for both a missing User-Password and an invalid LDAP bind. the Proxy-To-Realm always fires off.

Unifi wifi SSHA passwords freeradius

Hi! I have Unifi wifi — freeradius — ldap In LDAP i have SSHA password for users. This config on github help me to setup normal auth with SSHA passwords (instead plaintext) https://github.com/hacor/unifi-freeradius-ldap i use ttls + pap All ok, but i have some troubles with timeout (or something else) After a few hours wifi on clients (ios,android,pc) stops working. And users must manually reconnect to the wifi network When we use plaintext password and auth PEAP — all it’s ok.

LDAP groups and how to filter
by Daniel Oakes 12 Feb '20

12 Feb '20

Hi there, I've got FreeRadius working off a FreeIPA backend to try and sort some issues with a firewall that won't filter on LDAP groups correctly. I've got my queries working, but now want to use post-auth to update a Group Name that the firewall will expect. Just wondering how in debug mode I could print out to debug all the groups that the user is a memberOf so I can write that logic. Sorry if this has been answered previously, I've not found an example, and I'm not much of an LDAP person. Cheers, Daniel

2FA Challenge via Proxy Realm with valid State
by Bill Noyce 12 Feb '20

12 Feb '20

Hi, I was hoping to follow the clearly written Wiki article: https://wiki.freeradius.org/guide/2FA-Active-Directory-plus-Proxy My problem is that the 2FA Radius Proxy used to verify the OTP requires a valid State value, so currently the login process is a 3 step process! I have allowed State in the Pre-Proxy Attributes filter. So the current flow is: 1) Username/Password request via AD LDAP 2) Unsuccessful OTP request with invalid State value ( returns valid State value from the remote OTP Radius server ) 3) Successful OTP request Anyone able to suggest how I go about getting a valid State value from the OTP radius during the first Access-Request so that the first Access-Challenge response contains this valid State value? Thanks, Bill

VSA with Vendor 0 Attribute 0 - Have you ever seen this?
by Stefan Paetow 12 Feb '20

12 Feb '20

Hi all, Just a quick question... has anyone ever seen a RADIUS request/response containing a vendor-specific attribute with vendor 0, attribute 0? That's not an IANA packet, is it? I mean... IANA would just be non-VSA. Is this a possible misconfiguration somewhere?
