Freeradius V2 to V3 - Handle "Tagged" Attributes
by Kabsof 13 Mar '24

13 Mar '24

Hi everyone, hope you are well ! I'm currently trying to update a freeradius server from V2 to V3, and I'm struggling with tagged attributes that don't work correctly on the V3 server. This is what i have in my radreply table : +----------+-------------------------------------+------------------------+----+---------------------------+ | id | UserName | Attribute | op | Value | +----------+-------------------------------------+------------------------+----+---------------------------+ | 35928801 | userXX | Framed-Protocol | = | PPP | | 35928811 | userXX | Service-Type | = | Framed-User | | 35928821 | userXX | Tunnel-Server-Auth-Id | = | :1:xxxxxxxxxx | | 35928831 | userXX | Tunnel-Server-Endpoint | = | :1:xx.xx.xx.xx | | 35928841 | userXX | Tunnel-Medium-Type | = | IP | | 35928851 | userXX | Tunnel-Type | = | :1:L2TP | | 35928861 | userXX | Tunnel-Client-Auth-ID | = | :1:XX_XXX | | 35928901 |userXX | Tunnel-Password | = | :1:xxxxxx In the V2 server, the response is like this : Packet-Type = Access-Accept Framed-Protocol = PPP Service-Type = Framed-User Tunnel-Server-Auth-Id:1 = "xxxxxx" Tunnel-Server-Endpoint:1 = "xx.xx.xx.xx" Tunnel-Medium-Type:1 = IPv4 Tunnel-Type:1 = L2TP Tunnel-Client-Auth-Id:1 = "xx_XXX" Tunnel-Password:1 = "xxxxx" As you can see, the ":1:" contained in the value goes at the end of the attribute. I spent a lot of time trying to understand this on the V2 server, but I found nothing related to this configuration. It's like freeradiusV2 understands itself how to deal with tagged attributs. On the V3 server, it respond exactly what is on the radreply table : Packet-Type = Access-Accept Framed-Protocol = PPP Service-Type = Framed-User Tunnel-Server-Auth-Id = ":1:xxxxxxxx" Tunnel-Server-Endpoint = ":1:xx.xx.xx.xxx" Tunnel-Medium-Type = IPv4 Tunnel-Type = L2TP Tunnel-Client-Auth-Id = ":1:xxxxxxx" Tunnel-Password = ":1:xxxxxx" For now, i can't change nothing on my bdd, i have do deal it with freeradius I found nothing about changes between V2 and V3 about tagged attributes (i found something between v3 and v4) Do you have an idea, how can I make it work with V3 ? Regards, Kabsof

Access Attribute
by Brian Blater 13 Mar '24

13 Mar '24

I'm in the process of configuring FreeRADIUS to integrate with our Okta SSO and LDAP. I'm working through the documentation and FR installed and LDAP configured so far. Right now I'm looking at the "Controlling user accounts" info and had a question about the user.access_attribute and the user.access-positive attributes.In the documentation it mentions if the attribute is present (set to true) I can set the access_positive = yes. My question is this... in Okta the attribute is "organizationalStatus" and it can be one of several things. For an active user it is set to ACTIVE. Does FR only see true or false? Can I set this so it sees the attribute from Okta and if it is anything other than ACTIVE, then set access_positive = no? Thanks

Azure AD LDAP / memberOf / Not all groups being assigned to control:LDAP-Group
by Mike Mercier 07 Mar '24

07 Mar '24

Hello, Freeradius info: freeradius -v radiusd: FreeRADIUS Version 3.0.20, for host x86_64-pc-linux-gnu, built on Jan 4 2023 at 03:22:36 FreeRADIUS Version 3.0.20 more /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=20.04 DISTRIB_CODENAME=focal DISTRIB_DESCRIPTION="Ubuntu 20.04.6 LTS" I've been using pfSense + OpenVPN + FreeRadius, using an Azure AD LDAP backend successfully for quite a while now. This morning I had a user reach out to let me know they are unable to access specific resources via the OpenVPN client. As part of the post-auth, I am creating a Cisco-AVPair to dynamically create rules in pf, this is (was?) working as expected. What I discovered after some digging is that the 'control:LDAP-Group' variable is not being assigned all the groups the user is a member of. Since some groups are missing from the result, some of the post-auth group checks are never hit, so the firewall rule is not being added to the Cisco-AVPair ex: I have the following in the 'ldap' module server = 'ldaps://ldaps.domain.com' identity = '<username>@domain.com' password = '<password>' base_dn = 'dc=domain,dc=com' If I do an ldapsearch for the user using the variables above: ldapsearch -D '$identiry' -w '$password -H '$server' -b '$base_dn' '(&(objectClass=user)(sAMAccountName=<username>))' memberOf | grep ^memberOf | wc -l The command returns 112 groups for the user I have queried. When I run 'freeradius -f -XXX', and monitor the output for the above users login, the number of groups assigned to control:LDAP-Group is only 65. I have a different user who is a member of 70 groups, testing with that user I see the same result from the 'freeradius -f -XXX' output for this user as well, only 65 groups. Has anyone else experienced this? Is there a knob I have to tune somewhere that I am unaware of? Thanks, Mike

FreeRADIUS and Okta LDAP Interface
by Brian Blater 06 Mar '24

06 Mar '24

First time poster here, so bare with me. I've been using MS NPS for our WiFi authentication against AD. However, the company I work for is moving away from AD and going to Okta for all our directory needs and SSO. Okta supports RADIUS from a handful of proprietary systems. None of which we have. We are using Unifi APs for our WiFi. As is typically the case, I have ZERO budget for this. So, implementing an online proprietary system at $X/user/month isn't possible, all though much easier. So, I spun up a new Ubuntu VM and installed FreeRADIUS. I've already got the Okta LDAP Interface created and working. I've used it with both Jamf and ldapsearch. That piece seems to be working at this time. I have followed various instructions online and have FreeRADIUS up and working using a test user in the local sql db. Now the part of integrating it with Okta. I have searched all over for information on configuring FreeRADIUS with Okta and I've found very little. Okta does have a RADIUS agent for linux, but from my install and attempt to configure that I've found it lacking many features. Following what documentation I could find I have modified the ldap file and linked it to /mods-enabled/ldap. In the ldap { section I've modified the following: server identity password base_dn I've also made the necessary changes in the user and group sections. In the tls section I've changed start_tls = yes and specified the ca_file. Now I can't even get freeradius -X to start. I get the following when running that: /etc/freeradius/3.0/mods-enabled/ldap[8]: ldaps:// scheme is not compatible with 'start_tls' /etc/freeradius/3.0/mods-enabled/ldap[8]: Instantiation failed for module "ldap" If I change start_tls to no, I get the following: TLS: can't connect: (unknown error code). rlm_ldap (ldap): Bind with uid=<redacted>, dc=com to ldaps://redacted.ldap.okta.com:636 failed: Can't contact LDAP server rlm_ldap (ldap): Opening connection failed (0) rlm_ldap (ldap): Removing connection pool /etc/freeradius/3.0/mods-enabled/ldap[8]: Instantiation failed for module "ldap" One thing to mention here is when doing an ldapsearch using the following: ldapsearch -x -H ldaps://digitalturbine.ldap.okta.com -D "uid=<redacted>,dc=com" -W -b dc=redacted,dc=okta,dc=com uid=<username> I get results. This is of course using simple auth (-x), so I'm not having to use the cert for this and Jamf appears to be doing simple auth as well. Which appears to be the issue at this point. How do I configure FreeRADIUS ldap to do simple auth in this case? Must be something I'm missing in the ldap file, but can't put my finger on it. Once I get FR talking to the Okta LDAP instance I can move on to the other pieces I need to figure out how to configure - auth based on group membership, different sites etc. Any suggestions? Thanks, brian

Version 4 issue - Opening tacacs I/O interface failed

I've seen this error mentioned a few times with some google search and the advice was to ensure libkqueue is the most recent version from git which is 2.6.1 and i've done that: dpkg -l libkqueue Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Architecture Description +++-==============-============-============-=================================================================== ii libkqueue 2.6.1 amd64 Userspace implementation of the kqueue event notification mechanism I'm on ubuntu 20.04 and everything is up to date.

Problems with TACACS - Do i need to be on version 4?
by jeff cearniey 06 Mar '24

06 Mar '24

Hello I'm trying to set up a TACACS virtual server. I used the tacacs config file from here https://freeradius.org/documentation/freeradius-server/4.0.0/raddb/sites-av… but when i try to start the server i get this: "/etc/freeradius/sites-enabled/tacacs[21]: Invalid type "Authentication-Start" in listen section." I'm on version 3.2.3 using Ubuntu 20.04. Do i need to be on version 4 for TACACS? Thanks Phill

Variables usage and %explode function
by Ted S. 06 Mar '24

06 Mar '24

Hello, im using freeradius 3.2. I want extract from the TLS-Client-Cert-Common-Name only the Hostname and strip off the fqdn part and update the User-Name for further processings. I found the split string function with %explode in the documentation. I dont get it working, i tried following 2 variants: Variant 1 with variables: i tried using temp variables for conversion and used the "local variables" example from the documentation. I read that there variables only can be used in: "One of case, else, elsif, foreach, group, if ,limit, or timeout. Local variables are forbidden in all other locations." So i build a dummy "if" for that. if ("1"=="1") { string TmpString1 &TmpString1 := "%explode(%{TLS-Client-Cert-Common-Name}, '.')" &User-Name := "%{TmpString1[0]}$" } -> Error Log on Radiusd -X: /etc/raddb/sites-enabled/check-eap-tls[105]: Expecting section start brace '{' after "string TmpString1" -> the declaration looks like the example but what im doing wrong? Variant 2 without helping variables, in one line: update request { &User-Name := "%explode(%{TLS-Client-Cert-Common-Name}, '.')[0]" } -> Log: (10) update request { (10) EXPAND %explode(%{TLS-Client-Cert-Common-Name}, '.')[0] (10) --> 1xplode(testclient.prod.company.net, '.')[0] (10) &User-Name := 1xplode(testclient.prod.company.net, '.')[0] (10) } # update request = noop Can someone helping me, getting one of both variants working? Im also not sure if i can use [0] in the variant 2. many thanks and regards, Ted

TTLS EAP “unsupported protocol” error
by Bill Schoolfield 04 Mar '24

04 Mar '24

Trying to get Cambium 450 equipment to work with TTLS EAP and FreeRadius. Specifically FreeRadius 3.2.1 on Debian 12.5 Following all the information online, I’ve setup radius including creating my own certificates and tested the setup using the eapol_test tool. Results AOK. But tests with the 450 Cambium equipment (20.1 firmware) fail at the ssl handshake with an error message in the log: “unsupported protocol” I was able to get it to work by forcing TLS 1.0 (setting min and max TLS to 1.0 and setting cipher_list to DEFAULT@SECLEVEL=0). Obviously not a good thing to do but it does suggest a TLS version issue. My question to the group is this simply a matter of what Cambium supports (TLS wise) or is it possible I have something wrong on the FreeRadius side?

authenticate cisco nexus 5000 with freeradius
by Majed Zouhairy 29 Feb '24

Peace, according to https://community.cisco.com/t5/security-knowledge-base/nexus-integration-fo… the freeradius configuration is as such: DEFAULT Group == cisco-rw, Auth-Type = System Service-Type = NAS-Prompt-User, cisco-avpair := "shell:roles*\"network-admin vdc-admin\"", but it does not mention what section of freeradius to modify, i tried adding all the information to the user, but then free radius wouldn't restart. which means Default group needs to be added to a different section. any help?

logintime replacement
by Stephen Medina 29 Feb '24

29 Feb '24

I noticed that the logintime module is not in v4. Is there a recommended way of replacing it or should it be moved to an "external" module, e.g. rest, python? -Stephen
