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

Microsoft ODBC bug
by Dom Latter 05 Dec '19

05 Dec '19

Hi all, I have been experimenting with Microsoft SQL Server as a replacement for our current mysql servers [1]. I installed Microsoft's own "ODBC Driver 17 for SQL Server" and have tested against both SQL Server running on the same Linux machine as Freeradius itself, and SQL Server running on a Windows machine. In both cases I found the same (what appears to be a) bug, which I will describe below for the benefit of the archives, even though it is (probably) not a problem with freeradius. Because people hitting this are very likely to be searching with terms including "freeradius". Also there is a chance that it is somehow specific to the interaction with freeradius. Because it is hard to imagine even Microsoft releasing something with such a glaring fault. I'll also give a work-around. I think I will now try iodbc instead - anybody here used it? Right, the bug. Here's my custom attribute: ATTRIBUTE My-Int 3004 integer Here's part of the post-auth section in the "outer" site: update control { My-Int := "%{sql:SELECT 9999 }" My-Int := "%{sql:SELECT 10000 }" My-Int := "%{sql:SELECT '10000' }" Here's debug output: EXPAND %{sql:SELECT 9999 } --> 9999 My-Int := 9999 Executing select query: SELECT 10000 rlm_sql_unixodbc: 22003 [Microsoft][ODBC Driver 17 for SQL Server]Numeric value out of range ERROR: Error fetching row ERROR: Unknown error ERROR: SQL query failed: <INVALID> EXPAND %{sql:SELECT 10000 } --> My-Int := 0 Executing select query: SELECT '10000' EXPAND %{sql:SELECT '10000' } --> 10000 My-Int := 10000 As you can see, if an integer is more than four digits long, the driver throws an error. But if you return the number as a string, it works fine. I'd love to see the source code for this... [1] Everything else is SQL Server and our current integration between the two databases is rather clunky; a homogeneous environment makes sense, whatever I personally think of Microsoft <grin>.

Freeradius crashes with SIGABRT

Hi, our radius proxy crashes regularily since we switched from version 2 to 3. First we ran freeradius version 3.0.15 (package from Suse Linux Enterprise 12.4), then version 3.0.17 and 3.0.18 (compiled with rpmbuild) with no difference.

Radiusd hangs on redis cluster failover (sometimes)
by Milan Nikolic 26 Nov '19

26 Nov '19

Hello, I have an issue with FreeRADIUS 4.0.x and Redis cluster. When I shut down one of the nodes (all have freeradius and use redis cluster), redis recovers and cluster state is OK but it seems freeradius doesn't refresh cluster topology, and when I send a packet to one of the working nodes it is trying to send command to node that is down and then just hangs and doesn't return response. I cannot stop radiusd after that (i.e. ctrl+c doesn't work) and it must be killed. The last line in log is this, and nothing is printed after that: Debug : (7) rediswho - [16] >>> Sending command(s) to 192.168.1.8:7004 (fr_redis_cluster_state_init) Btw. I changed the message in cluster.c just to confirm which function is called (there are two same Sending command(s) msg in that file), it is this line https://github.com/FreeRADIUS/freeradius-server/blob/master/src/lib/redis/c… . So 192.168.1.8 is the node that I shut down to test high availability, and I send packet after redis is recovered. This doesn't happen when I shut down the other node, I can see in log how radius refreshes cluster topology and everything just continues to work. Before every test, I always make sure cluster state is ok and master/slaves are in balance on all nodes. Attached is a log file I get with `radiusd -X` on the node that fails and hangs after it tries to contact node that is down. Thanks, Milan

Can't get FreeRADIUS to work with a Samba DC (MSCHAP)
by Oleg Blyahher 06 Nov '19

06 Nov '19

Hi all, I understand my issue is not unique. I have a Samba DC running samba 4.6.7 on Ubuntu 16.04. I'm now trying to set up FreeRADIUS 3 (3.0.16) with SMB 4.7.6 on Ubuntu 18.04 to authenticate against the Samba DC. Running "radtest aduser password localhost:18120 0 testing123" works. Running "radtest -t mschap aduser password localhost:18120 0 testing123" does not work. I have added this into the smb.conf on both servers: ntlm auth = yes I have been basically following these tutorials: * https://blog.svedr.in/posts/freeradius-peapv0+mschapv2-howto/ * http://deployingradius.com/documents/configuration/active_directory.html * https://wiki.samba.org/index.php/Authenticating_Freeradius_against_Active_D… I would also like to add a comment on the fact that I cannot restart smbd on the DC if I put the following line (nothing in the Samba log nor syslog): ntlm auth = mschapv2-and-ntlmv2-only I have also tried to set up a Microsoft Radius server (join it to the same domain), but got the same results ("wrong password"), so I actually suspect there might be something wrong with the Samba DC. Unfortunately, I couldn't find so much information on how the DC should be.

RE: OCSP Response Signed by other CA
by Mike DiBella 31 Oct '19

31 Oct '19

In testing my OCSP responder configuration I've found that the following openssl command: openssl ocsp -issuer client_cer_root.cer -cert client.cer -VAfile ocsp_signer.cer -url http://ocsp.responder.net/ocsp returns: Response verify OK client.cer: good This Update: Oct 31 11:43:47 2019 GMT Next Update: Nov 2 00:03:47 2019 GMT I see that there is a client keyword in the verify section of the eap configuration file. I'm wondering if I can I substitute this command for the default openssl verify command prototyped in the file? In my testing, it looks like openssl returns exit 0 for both verified and responder errors, so I'm wondering how freeradius parses the result of the command. From: Mike DiBella Sent: Wednesday, October 30, 2019 3:08 PM To: 'freeradius-users(a)lists.freeradius.org' <freeradius-users(a)lists.freeradius.org> Subject: OCSP Response Signed by other CA I'm attempting to add OCSP certificate verification to EAP, but my responder hosts multiple CAs and signs the responses with a cert common to all. I think freeradius is assuming that the signer of the OCSP response will be the same as the signer of the client certificate, and I can't see an option to override this behavior. I've already tried concatenating the OCSP signer to the client trust certificate file, but freeradius still fails validation with "Error: rlm_eap: SSL error error:27069070:OCSP routines:OCSP_basic_verify:root ca not trusted". Any ideas?

802.1x / EAP Assistance
by J Kephart 31 Oct '19

31 Oct '19

Good morning! We are attempting to implement 802.1x/EAP for the first time, ad we're having some trouble diagnosing what's going on in the various stages of the communications between the NAS and FR. We don't have any experience with it, so it's rather confusing. We're using FR 2.2.8, with the test certs provided. We can see that there is communication, but all attempts to authenticate a device are failing. I've included what I believe to be the relevant portion of the debug output, and I do see several error conditions. The first says that the realm LOCAL is not defined, but in looking at the config, it looks as though it is. There's also a report that there's a missing Cleartext-Password, but that is also defined in the database, so we're at a loss as to the cause of the failure. If someone can point us in the right direction, I'd truly appreciate it! rad_recv: Access-Request packet from host 146.115.19.180 port 50987, id=97, length=394 Acct-Session-Id = "5DB9E1F5-76DF7502" User-Name = "jerry" NAS-IP-Address = 192.168.185.30 NAS-Identifier = "90-3A-72-15-25-1D" NAS-Port = 1 Called-Station-Id = "90-3A-72-15-25-1D:CVGNE_W1" Calling-Station-Id = "D4-53-83-F3-C0-17" Service-Type = Framed-User Chargeable-User-Identity = "" NAS-Port-Type = Wireless-802.11 Connect-Info = "CONNECT 802.11a/n/ac" EAP-Message = 0x0208005f1900170303005400000000000000022f4cd34458205cfb0d339d2a9f6dda68b5f7a4ffbd985bbfb9ef4094114e5a1856df8479ea3c4ddc7f293487a00396643c97c4b24f51d67a7c7cc34e9bbbc1c156adc07977d4e095d6fddaa5 State = 0x957bdc849273c5bfd96a2d7f79095e2d Ruckus-SSID = "CVGNE_W1" Ruckus-Attr-14 = 0x903a7215251d Ruckus-Attr-9 = 0x000001c3 Ruckus-SCG-CBlade-IP = 3232282885 Ruckus-Attr-134 = 0x44656661756c74205a6f6e65 Ruckus-Attr-135 = 0x4356474e455f5731 Message-Authenticator = 0xad0239941dd1cf346629d1f1b23805b6 Event-Timestamp = "Oct 30 2019 15:18:14 EDT" Proxy-State = 0x3636 # Executing section authorize from file /etc/raddb/sites-enabled/default +group authorize { ++[preprocess] = ok ++update request { sql_xlat expand: select zone_migration_enabled from sites where id='%{NAS-Identifier}' -> select zone_migration_enabled from sites where id='90-3A-72-15-25-1D' rlm_sql (sql_instance2): Reserving sql socket id: 2 SQL query did not return any results rlm_sql (sql_instance2): Released sql socket id: 2 expand: %{sql_instance2: select zone_migration_enabled from sites where id='%{NAS-Identifier}'} -> ... expanding second conditional expand: %{%{sql_instance2: select zone_migration_enabled from sites where id='%{NAS-Identifier}'}:-0} -> 0 ++} # update request = noop ++? if (("%{Called-Station-Id}" =~ /^00-50-E8-/ || "%{Called-Station-Id}" =~ /^20-4C-03-/ )&& Tmp-String-2 == '1') expand: %{Called-Station-Id} -> 90-3A-72-15-25-1D:CVGNE_W1 ??
