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

No auth requests through TLS tunnel if connection was checked
by nabble＠felix.world 03 Jan '25

03 Jan '25

Hi there, I want to make some additional checks for RadSec connections. After I’ve set `check_client_connections` to `yes`, the server is handling the connection over the auth type "Autz-Type New-TLS-Connection”. So far so good but after the connection has accepted, no further traffic is reaching the radius server. I can see in packet captures that Access-Requests are send to the server and on the server netstat is also showing that packets are going to the socket which FreeRADIUS opens but only the queue is getting higher and never processed. After seeing this behaviour, of course also tested the behaviour with the default config. Just enabled tls, changed the `check_client_connections` and added a ip wildcard to the radsec clients. Since I haven’t found any open GitHub issue or something on this list I assume either no one is using the functionality or there is something I’ve overlooked. The radius server is running as docker container but that shouldn't make any difference. Output from $ netstat -apc: ``` Active UNIX domain sockets (servers and established) Proto RefCnt Flags Type State I-Node PID/Program name Path Active Internet connections (servers and established)

Can I use diffrent root CA certificates while dynamic loading certificate chains?
by James Fan 28 Oct '24

28 Oct '24

Hi, we have a case that, with multi-tenancy, there will be multiple CA certificates in our FreeRadius server, so we need to load the certificate chains dynamically. But when I use the statements below, I can't include the CA certificates in the certificate files I set. The TLS-Session-Cert-File looks like it is only for the server certificate and intermediate CA certificates. Is there any chance of dynamic loading certificate chains with root CA certificates? Thanks. authenticate { ... Auth-Type eap { if ("%{unpack:&EAP-Message 4 byte}" == 1) { update control { TLS-Session-Cert-File := "${certdir}/realms/%{Realm}" } } eap } ... }

Updates to some dictionary files - infinera, transmode, coriant
by Chris Wopat 05 May '24

05 May '24

We recently updated freeradius, and noticed that it came with a "dictionary.infinera". Generally we're looking to see if this project is interested in some updates to this file. What's listed in the file that comes with FreeRADIUS is actually "transmode" (an infinera acquisition). We have 3 definition files we use for Inffinera, one is "actual infinera", one is "coriant" and one is "transmode". Posting here with hopes they get integrated into FreeRADIUS, as many of htem were barely documented things deep inside these vendor's docs. If it's kosher to put vendor acquisitions inside their current vendor's file, then adding them to "dictionary.infinera" is good. If not, I'd split off what is currently in the infinera dictionary to be transmode. file details below: # dictionary.coriant: VENDOR Coriant 42229 BEGIN-VENDOR Coriant #g30 chassis ATTRIBUTE Coriant-Priv-Lvl 1 integer ATTRIBUTE Coriant-User-Class 2 string ATTRIBUTE Coriant-Timeout 3 integer ATTRIBUTE Coriant-Max-Sessions 5 integer #tnms ATTRIBUTE Coriant-TNMS-UserGroup 6 string END-VENDOR Coriant # dictionary.transmode VENDOR Transmode 8708 BEGIN-VENDOR Transmode ATTRIBUTE Infinera-User-Category 1 string ATTRIBUTE Infinera-ENM-User-Category 2 string END-VENDOR Transmode # dictionary.infinera VENDOR Infinera 21296 BEGIN-VENDOR Infinera # For privilege attributes 1 - 16 ATTRIBUTE Infinera-User-Priv-SA 1 integer ATTRIBUTE Infinera-User-Priv-NA 2 integer ATTRIBUTE Infinera-User-Priv-NE 3 integer ATTRIBUTE Infinera-User-Priv-PR 4 integer ATTRIBUTE Infinera-User-Priv-TT 5 integer ATTRIBUTE Infinera-User-Priv-MA 6 integer ATTRIBUTE Infinera-User-Priv-RA 7 integer ATTRIBUTE Infinera-User-AdminDomain 100 string ATTRIBUTE Infinera-User-Max-Concurrent-Session 101 integer ATTRIBUTE Infinera-User-Allowed-Timezone-Config 102 integer ATTRIBUTE Infinera-User-TimeZone 103 string ATTRIBUTE Infinera-User-Email-ID 110 string ATTRIBUTE Infinera-User-Email-Notification 111 integer ATTRIBUTE Infinera-User-Email-Alarm-Type 112 integer ATTRIBUTE Infinera-User-Email-Filter-Name 113 string ATTRIBUTE Infinera-User-Email-AdminDomain 114 string # For Misc Session Attributes 17 - 32 ATTRIBUTE Infinera-User-SessionTimeout 17 integer ATTRIBUTE Infinera-User-LockedOut 19 integer ATTRIBUTE Infinera-User-CanUseResSession 20 integer #For Mgmt Type based privileges 33 - 40 ATTRIBUTE Infinera-User-MgmtType-EMS 33 integer ATTRIBUTE Infinera-User-MgmtType-GNM 34 integer ATTRIBUTE Infinera-User-MgmtType-TL1 35 integer ATTRIBUTE Infinera-User-MgmtType-CLI 36 integer ATTRIBUTE Infinera-User-MgmtType-NETCONF 37 integer #reserved attributes 240 - 255 #240 - 248 for reserved strings ATTRIBUTE Infinera-Rsvd-Str-Attribute1 240 string ATTRIBUTE Infinera-Rsvd-Str-Attribute2 241 string #249 - 255 for reserved strings ATTRIBUTE Infinera-Rsvd-Int-Attribute1 249 integer ATTRIBUTE Infinera-Rsvd-Int-Attribute2 250 integer #Values for corresponding attributes. #SA,NA,NE,PR,TT Values VALUE Infinera-User-Priv-SA SA-NONPRIVILEGED 0 VALUE Infinera-User-Priv-SA SA-PRIVILEGED 1 VALUE Infinera-User-Priv-NA NA-NONPRIVILEGED 0 VALUE Infinera-User-Priv-NA NA-PRIVILEGED 1 VALUE Infinera-User-Priv-NE NE-NONPRIVILEGED 0 VALUE Infinera-User-Priv-NE NE-PRIVILEGED 1 VALUE Infinera-User-Priv-PR PR-NONPRIVILEGED 0 VALUE Infinera-User-Priv-PR PR-PRIVILEGED 1 VALUE Infinera-User-Priv-TT TT-NONPRIVILEGED 0 VALUE Infinera-User-Priv-TT TT-PRIVILEGED 1 VALUE Infinera-User-Priv-MA MA-NONPRIVILEGED 0 VALUE Infinera-User-Priv-MA MA-PRIVILEGED 1 VALUE Infinera-User-Priv-RA RA-NONPRIVILEGED 0 VALUE Infinera-User-Priv-RA RA-PRIVILEGED 1 VALUE Infinera-User-Allowed-Timezone-Config TIMEZONE-CONFIG-ALLOW 1 VALUE Infinera-User-Allowed-Timezone-Config TIMEZONE-CONFIG-NOT-ALLOW 0 VALUE Infinera-User-Email-Notification EMAIL-NOTIFICATION-ENABLE 1 VALUE Infinera-User-Email-Notification EMAIL-NOTIFICATION-DISABLE 0 VALUE Infinera-User-Email-Alarm-Type EMAIL-ALARM-TYPE-ALL 0 VALUE Infinera-User-Email-Alarm-Type EMAIL-ALARM-TYPE-NEW 1 VALUE Infinera-User-Email-Alarm-Type EMAIL-ALARM-TYPE-CLEAR 2 #Misc Attributes's values setting VALUE Infinera-User-CanUseResSession CANNOT-USE-RES-SESSION 0 VALUE Infinera-User-CanUseResSession CAN-USE-RES-SESSION 1 #Mgmt Type Values VALUE Infinera-User-MgmtType-EMS MGMTTYPE-EMS-DISALLOWED 0 VALUE Infinera-User-MgmtType-EMS MGMTTYPE-EMS-ALLOWED 1 VALUE Infinera-User-MgmtType-TL1 MGMTTYPE-TL1-DISALLOWED 0 VALUE Infinera-User-MgmtType-TL1 MGMTTYPE-TL1-ALLOWED 1 VALUE Infinera-User-MgmtType-GNM MGMTTYPE-GNM-DISALLOWED 0 VALUE Infinera-User-MgmtType-GNM MGMTTYPE-GNM-ALLOWED 1 VALUE Infinera-User-MgmtType-GNM MGMTTYPE-CLI-DISALLOWED 0 VALUE Infinera-User-MgmtType-GNM MGMTTYPE-CLI-ALLOWED 1 VALUE Infinera-User-MgmtType-GNM MGMTTYPE-NETCONF-DISALLOWED 0 VALUE Infinera-User-MgmtType-GNM MGMTTYPE-NETCONF-ALLOWED 1 VALUE Infinera-Rsvd-Int-Attribute1 INFINERA 1 END-VENDOR Infinera

Post-Autz New-TLS-Connection
by nabble＠felix.world 29 Apr '24

29 Apr '24

Hi, In the 3.2.x branch, with the `Autz-Type New-TLS-Connection` it is possible to log the certificate details of the client trying to connect and check some additional things. Is there also a Post-Autz or something similar to log the certificate details if the client certificate has been rejected? I’m not able to find something in the documentation so the answer may be `no` but in case I’ve missed something would be great to point me to the docs. BR, Lineconnect

ldap xlat syntax
by Christopher Nighswonger 27 Apr '24

27 Apr '24

G'day, Background: Debian GNU/Linux 11 (bullseye) FreeRADIUS Version 3.0.21 Samba Version 4.16.11-Debian (AD) Freeradius does user authentication against the Samba AD backend using ntlm_auth/mschapv2 and this works flawlessly. Problem: I'm looking at the doc for ldap xlat syntax: https://wiki.freeradius.org/modules/Rlm_ldap#ldap-xlat The following ldapsearch query works and returns a list of sAMAccountNames which are members of the 'staff' group. ldapsearch -D "cn=Administrator,cn=Users,dc=foo,dc=bar,dc=com" -w super_secret! -h "localhost" -b "cn=Users,dc=foo,dc=bar,dc=com" -s sub "(&(objectclass=user)(memberOf=CN=staff,CN=Users,DC=foo,DC=bar,DC=com))" sAMAccountName I am trying to replicate this in an ldap xlate inside the post-auth section like so: update reply { Reply-Message += "AD-Group: %{ldap:ldap:///cn=Users,dc=foo,dc=bar,dc=com?(&(objectclass=user)(memberOf=CN=staff,CN=Users,DC=foo,DC=bar,DC=com))?sAMAccountName}", } However, freeradius complains: (12) update reply { (12) ERROR: Parsing LDAP URL failed (12) EXPAND AD-Group: %{ldap:ldap:///cn=Users,dc=foo,dc=bar,dc=com?(&(objectclass=user)(memberOf=CN=staff,CN=Users,DC=foo,DC=bar,DC=com))?sAMAccountName} (12) --> AD-Group: (12) Reply-Message += AD-Group: Questions: 1. Is this sort of query possible using ldap xlat? 2. If so, am I missing something obvious? 3. Is there a way to test/debug ldap xlat expressions which is more efficient/simple than embedding them in the config and testing? Thanks, Chris

Ability to disable SSL certificate checking for LDAPS (636)?
by Chris Wopat 26 Apr '24

26 Apr '24

We're rebuilding some radius servers from Centos 7 to Ubuntu 22, due to the Centos 8 debacle. Both are 3.0.x. We ported our config over, which uses LDAPS:// on 636 on a Microsoft Windows 2022 AD server. We do not want to use TLS on 389. Something seems different behaviourally between the servers, the new Ubuntu server (FreeRADIUS 3.0.26) appears to be attempting to validate the certificate much more heavily. This must be an AD thing, but we get this stuff about "DomainDnsZones" and "ForestDnsZones" when we attempt to authenticate, and it hence fails. The bind is successful and omitted below: ======================================== TLS: hostname (ForestDnsZones.ad.MYDOMAIN.net) does not match common name in certificate (ad.MYDOMAIN.net) TLS: can't connect: (unknown error code). Unable to chase referral "ldaps://ForestDnsZones.ad.MYDOMAIN.net/DC=ForestDnsZones,DC=ad,DC=MYDOMAIN,…" (-1: Can't contact LDAP server) TLS: hostname (DomainDnsZones.ad.MYDOMAIN.net) does not match common name in certificate (ad.MYDOMAIN.net) TLS: can't connect: (unknown error code). Unable to chase referral "ldaps://DomainDnsZones.ad.MYDOMAIN.net/DC=DomainDnsZones,DC=ad,DC=MYDOMAIN,…" (-1: Can't contact LDAP server) ======================================== While debugging I saw somewhere that Centos OpenSSL may be compiled or configured differently than Ubuntu, and perhaps that's why. >From our ldap conf: server = "ldaps://ad.MYDOMAIN.net" port = 636 identity = "CN=freeradius,OU=Applications,DC=ad,DC=MYDOMAIN,DC=net" password = <> base_dn = "DC=ad,DC=MYDOMAIN,DC=net" options { chase_referrals = yes #chase_referrals = no } tls { ca_file = ${certdir}/DigiCertGlobalRootG2.crt.pem start_tls = no } Seeing if any options exist outside of regenerating/re-issueing / re-installing this cerficate, adding "DomainDnsZones" and "ForestDnsZones" to it? I can't find any docs for this, but is there any type of "don't validate" flag? I've set chase_referrals to no, and it still won't work (but it doesn't give the above error). Cheers Chris

Question on client retransmit behavior
by Brian Julin 25 Apr '24

25 Apr '24

So an EAP 802.1x supplicant can do one of the following if it receives no response from the NAS: 1) Restart EAP from the top. 2) Retransmit packets from the ongoing EAP session. 3) Just wait and maybe the NAS retransmits for it. 4) (Hopefully not) have a really old proxy in the chain that does retransmits for the NAS/client. If anyone has had the time to go down this rabbithole, is there any uniformity of client behavior here? That's really all I want to know... just trying to figure out if turning off NAS-initiiated retransmits is a wise move. But, if you'd like to hear a scary story, pull up a chair, I am glad to oblige: Lately we've had quite a few eduroam guest clients show up sending to lame servers that do not respond. Also, lately, supplicants have seem to have been getting quite aggressive at re-launching frequent authentication attempts after failures. But what good zombie doesn't enjoy bumping repeatedly against the door? Our NAS units serve these clients and our home users on the same SSID (we do fortunately have an additional non-"eduroam" one as well, where one can seek refuge, but many of our users are... adventurous) The NAS units have no idea that these two groups of users are different. So... in the wee hours of the night... ...when not many people are around to provide good authentications, ...when a lame eduroam guest client manages to authenticate three times (cue withered hand lifting a cast iron door knocker, spooky music, three loud knocks) ...the NAS declares our proxy dead. It then rolls over to another proxy, and declares it dead as well, if it happens again. Despite all that is evident to the naked eye, this NAS does not believe in zombies. So... it won't retry any of the dead servers until a generous timeout goes by. Oh yeah, and no Status-Server support. (cue suspensful music) the serial proxy killer is on the loose. Once all proxies are dead, no client can authenticate for quite a few minutes (cue tumbleweed) Our front-end proxy is a FreeRADIUS server. This then proxies to... a haunted old house owned by a mysterious vendor. Which... retransmits proxied requests. Yes. That old. There appears (sigh) to be no way to turn this behavior off. It also has a maximum 5 second timeout between retransmits, and though it will respond to Status-Server requests, it will not send them to upstream proxies. You can imagine the mess that makes (cue pixelized gore) On the other side... well we're special we have backend servers... but this could happen to anyone, since all eduroam requests go to the same TLRS system. You may be able to protect your own users, but you are not able to keep your guests safe from one another. If just one zombie gets into the guest house, all your friends may find themselves... well... So we have been trying to kill the zombies on the back-end... but 5 seconds, minus 1 for the reject-delay, minus 1 for the DMZ proxy reject delay... 3 seconds is perhaps a bit tight for a 7-way handshake zig-zagging across the globe as it trickles through the federation servers. Now we're resorting to slaughtering zombies on the front end before they manage to get to the haunted house on clearpass lane. Ooops. Did I just name names? So sorry. Forget I said that. This of course messes up our logs, since only the NAS and the front end server see the rejection. Not that the logs were in great condition to start out, since it appears plenty of clients are now configured to just drop their EAP conversation if they are rejected in the inner tunnel, before issuing the outer tunnel challenge to get an outer tunnel Access-Reject. And finally, the haunted house... it logs all such occurences simply as just "timeout"s, unless you drill down to see whether the timeout was client or server side. But what's a little salt in the headwound, after all. Anyway, thank you for patronizing our hanted-house ride. Remember to collect your belongings as you leave the carts and... try to get a good night's sleep.
