rlm_ldap: Successful login with empty password
by Simon N 06 May '24

06 May '24

Hello everyone, I am currently testing version 4. I am using the latest commit (3b422574). I noticed that if the LDAP module is configured with an Active Directory, a user can successfully log in with an empty password. I think that this behaviour is not correct or? It also works with the Radius protocol instead of Tacacs and with Alpha version 4. First I perform the login with the correct password and then with an empty password.

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.

tunneled_reply vs outer.session-state
by Jack Carter 21 Apr '24

21 Apr '24

Hi there, I have a configuration which operates successfully with ‘use_tunneled_reply” set to yes. I am trying to remove the depreciated use_tunneled_reply in place of updating the outer.session-state but can’t seem to get it working.

Add TLS version to logs with linelog
by dominic.stalder＠unibe.ch 17 Apr '24

17 Apr '24

Hi everyone This is my very first contact with the FreeRadius users mailing list, so please feel free to point me into the right direction about the interaction with this mailing list. Happy to learn how to use it correctly / efficiently. What I am trying to do and why I am trying to do it: I am also very new to FreeRadius per se and I am in the middle of a server lifecycle. Our actual production servers run on version 3.0.12 and the new ones have version 3.0.26 installed. As we are an University with a lot of BYOD clients, we still support TLS 1.0 and TLS 1.1 and want to get rid of TLS 1.0 and TLS 1.1 in the near future. To know about the consequences, I would like to get a rough number of how many clients still using those old TLS versions. I know I can enable / increase the debug level in /etc/freeradius/3.0/radiusd.conf to see the TLS version used for all authentications, BUT this will fill up our logging partition pretty quick. *** What you expect the server to do: I would like to have a way to log the client TLS version used in /var/log/authz.log via the linelog module. At the moment, the linelog configuration (/etc/freeradius/3.0/mods-available/linelog) looks like this: linelog 802.1x_authz_log { filename = ${logdir}/authz.log reference = "sp.%{%{reply:Packet-Type}:-format}" sp { Access-Accept = "%t : AuthZ: (%I) Access-Accept: [%{%{reply:User-Name}:-%{User-Name}}] TLS=%{%{TLS-Client-Version}:-NULL} SSID=%{%{request:Called-Station-SSID}:-NULL} Calling-Station-Id=%{%{request:Calling-Station-Id}:-Unknown} Called-Station-Id=%{%{request:Called-Station-Id}:-Unknown} Filter-ID=%{%{reply:Filter-Id}:-NULL} VLAN=%{%{reply:Tunnel-Private-Group-Id}:-NULL} Class=%{%{reply:Class}:-NULL} (from client %{Client-Shortname} port %{%{request:Nas-Port}:-0} cli %{%{request:Calling-Station-Id}:-Unknown})" } } The post-auth configuration in /etc/freeradius/3.0/sites-available/default looks like this: post-auth { update { &reply: += &session-state: } if (EAP-Message) { 802.1x_authz_log } Is there a way to print out the TLS version in the AuthZ part and if yes, how? freeradius -X: id-radiustest1:~# freeradius -X FreeRADIUS Version 3.0.26 Copyright (C) 1999-2021 The FreeRADIUS server project and contributors There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE You may redistribute copies of FreeRADIUS under the terms of the GNU General Public License For more information about these matters, see the file named COPYRIGHT Starting - reading configuration files ... including dictionary file /usr/share/freeradius/dictionary including dictionary file /usr/share/freeradius/dictionary.dhcp including dictionary file /usr/share/freeradius/dictionary.vqp including dictionary file /etc/freeradius/3.0/dictionary including configuration file /etc/freeradius/3.0/radiusd.conf including configuration file /etc/freeradius/3.0/proxy.conf including configuration file /etc/freeradius/3.0/clients.conf including files in directory /etc/freeradius/3.0/mods-enabled/ including configuration file /etc/freeradius/3.0/mods-enabled/preprocess including configuration file /etc/freeradius/3.0/mods-enabled/expr including configuration file /etc/freeradius/3.0/mods-enabled/sradutmp including configuration file /etc/freeradius/3.0/mods-enabled/dynamic_clients including configuration file /etc/freeradius/3.0/mods-enabled/always including configuration file /etc/freeradius/3.0/mods-enabled/linelog including configuration file /etc/freeradius/3.0/mods-enabled/files including configuration file /etc/freeradius/3.0/mods-enabled/cache_eap including configuration file /etc/freeradius/3.0/mods-enabled/eap including configuration file /etc/freeradius/3.0/mods-enabled/attr_filter including configuration file /etc/freeradius/3.0/mods-enabled/realm including configuration file /etc/freeradius/3.0/mods-enabled/detail including configuration file /etc/freeradius/3.0/mods-enabled/unpack including configuration file /etc/freeradius/3.0/mods-enabled/detail.log including files in directory /etc/freeradius/3.0/policy.d/ including configuration file /etc/freeradius/3.0/policy.d/operator-name including configuration file /etc/freeradius/3.0/policy.d/debug including configuration file /etc/freeradius/3.0/policy.d/filter including configuration file /etc/freeradius/3.0/policy.d/accounting including configuration file /etc/freeradius/3.0/policy.d/canonicalization including configuration file /etc/freeradius/3.0/policy.d/rfc7542 including configuration file /etc/freeradius/3.0/policy.d/cui including configuration file /etc/freeradius/3.0/policy.d/eap including configuration file /etc/freeradius/3.0/policy.d/control including files in directory /etc/freeradius/3.0/sites-enabled/ including configuration file /etc/freeradius/3.0/sites-enabled/default including configuration file /etc/freeradius/3.0/sites-enabled/proxy-inner-tunnel including configuration file /etc/freeradius/3.0/sites-enabled/control-socket main { security { user = "freerad" group = "freerad" allow_core_dumps = no } name = "freeradius" prefix = "/usr" localstatedir = "/var" logdir = "/var/log/freeradius" run_dir = "/var/run/freeradius" } main { name = "freeradius" prefix = "/usr" localstatedir = "/var" sbindir = "/usr/sbin" logdir = "/var/log/freeradius" run_dir = "/var/run/freeradius" libdir = "/usr/lib/freeradius" radacctdir = "/var/log/freeradius/radacct" hostname_lookups = no max_request_time = 30 cleanup_delay = 5 max_requests = 16384 postauth_client_lost = no pidfile = "/var/run/freeradius/freeradius.pid" checkrad = "/usr/sbin/checkrad" debug_level = 0 proxy_requests = yes log { stripped_names = no auth = yes auth_badpass = no auth_goodpass = no colourise = yes msg_denied = "You are already logged in - access denied" } resources { } security { max_attributes = 200 reject_delay = 1.000000 status_server = yes } } radiusd: #### Loading Realms and Home Servers #### proxy server { retry_delay = 5 retry_count = 3 default_fallback = no dead_time = 120 wake_all_if_all_dead = no } ... radiusd: #### Loading Clients #### ...

failed memcached server handling
by Eric Lin 16 Apr '24

16 Apr '24

Hi Everyone, I am testing Freeradius v3.2.3 with cache module. the driver "rlm_cache_memcached". We plan to build a freeradius cluster with distributed memcached to cache user login status. During the test, I notice if memcached is offline, freeradius will either reject all new auth request or failed to start. The libmemcached document website is offline (http://docs.libmemcached.org) and I tried to search related information on google, but no luck. Does anyone know how to make rlm_cache_memcached to handle failed memcached server? the cache module config is cache { driver = "rlm_cache_memcached" memcached { # Memcached configuration options, as documented here: # http://docs.libmemcached.org/libmemcached_configuration.htmlmemcached options = "--SERVER=10.4.4.5 --SERVER=10.4.4.6 --SERVER=10.4.4.7" pool { start = ${thread[pool].start_servers} min = ${thread[pool].min_spare_servers} max = ${thread[pool].max_servers} spare = ${thread[pool].max_spare_servers} uses = 0 lifetime = 0 idle_timeout = 60 } } key = "%{sha256:%{User-Name}}/%{sha256:%{User-Password}}" ttl = 150 update { # <list>:<attribute> <op> <value> # Cache all instances of Reply-Message in the reply list &reply:Reply-Message += &reply:Reply-Message[*] # Add our own to show when the cache was last updated &reply:Reply-Message += "Cache last updated at %t" } } also, the option --REMOVE_FAILED_SERVERS is not supported Regards, Eric
