Authenticate with machine account and without ntlm_auth
by Rodrigo Antunes 19 Nov '24

19 Nov '24

Hi, I'd like to authenticate a PC using it's machine account and the mschap module, without calling ntlm_auth, is this possible? I noticed that the machine send its user as "host/machinename" but I don't know how to obtain and check its password. Maybe I should check the nt-hashes in users file? Thanks

How to get FR user check items override group check items
by Abraham Jacob 18 Nov '24

18 Nov '24

I have been using FreeRADIUS 1.1 (yeah very old) on an old Debian server over the years without any issues. Thank you for wonderful software! Now, as part of the server upgrade, I tried installing version 3.2.1 in Debian 12 and I was able to configure it except for one issue. In v1.1 user attributes get priority over group items. I am using the same SQL tables from v1.1. There I am setting Session-Timeout to 3600 in the radgroupcheck table. For some select users I set Session-Timeout differently, say 7200. In v1.1, I am seeing Session-Timeout = 7200 for Access-Accept while in v3.2.1 it is 3600. I checked the server in debug mode and found following <snip> .... (0) sql: User found in radcheck table (0) sql: Conditional check items matched, merging assignment check items (0) sql: Session-Timeout := 7200 (0) sql: Crypt-Password := "$1$bd1rxwue$ab3wiY34Cjfk5QM13/vNy0" .... (0) sql: User found in the group table (0) sql: EXPAND SELECT id, groupname, attribute, Value, op FROM radgroupcheck WHERE groupname = '%{S QL-Group}' ORDER BY id (0) sql: --> SELECT id, groupname, attribute, Value, op FROM radgroupcheck WHERE groupname = 'VPN -60-Min' ORDER BY id (0) sql: Executing select query: SELECT id, groupname, attribute, Value, op FROM radgroupcheck WHERE groupname = 'VPN-60-Min' ORDER BY id (0) sql: Group "VPN-60-Min": Conditional check items matched (0) sql: Group "VPN-60-Min": Merging assignment check items (0) sql: Session-Timeout := 3600 .... (0) dailycounter: Allowing user, &control:Session-Timeout value (3600) is greater than counter value (0) (0) dailycounter: Setting &reply:Session-Timeout value to 3600 .... Sent Access-Accept Id 55 from 192.168.3.180:1812 to 192.168.3.180:39999 length 32 (0) Idle-Timeout = 600 (0) Session-Timeout = 3600 (0) Finished request </snip> So I think this is the expected behaviour in the new version. Following are the sql contents. Table radgroupreply: +----+------------+--------------+----+-------+ | id | groupname | attribute | op | value | +----+------------+--------------+----+-------+ | 9 | VPN-60-Min | Idle-Timeout | := | 600 | +----+------------+--------------+----+-------+ Table radgroupcheck: +----+------------+-----------------+----+-------+ | id | groupname | attribute | op | value | +----+------------+-----------------+----+-------+ | 2 | VPN-60-Min | Session-Timeout | := | 3600 | +----+------------+-----------------+----+-------+ Table: radcheck: +----+----------+-----------------+----+------------------------------------+ | id | username | attribute | op | value | +----+----------+-----------------+----+------------------------------------+ | 18 | vpn-user | Session-Timeout | := | 7200 | | 19 | vpn-user | Crypt-Password | := | $1$bd1rxwue$ab3wiY34Cjfk5QM13/vNy0 | +----+----------+-----------------+----+------------------------------------+ Now my question: Is there any configuration options available to get the old v1.1 behaviour? This way I don't have to set Session-Timeout for all my users, just a select few who need to be different from default. Thanks Abraham

Using the rest module
by Francis Augusto Medeiros-Logeay 17 Nov '24

17 Nov '24

Hi, I’m fairly new to Freeradius, and today I took the time to read the documentation and to search what’s a best practice to implement some polling-based (blocking) authentication with FreeRADIUS towards a rest api server. I tried with Python first, but since I’m having trouble with concurrency, so I’m exploring other alternatives. The rest module seems like a fit, but I didn’t find much about other possibilities rather than interpreting the response code and having a json as a response that match existing attributes. In my case, I need simply to evaluate a value of a nested json key that doesn’t really match any existing attributes. Is there a way to do it? For example: { ‘detail’ : { ‘ result’ : { ‘value’ :’true’}}} I need to authenticate that user based on the value of ‘value’. Is the rest module a good tool for this? I saw that there is a json module that might be used with the rest, but it doesn’t seem to be available for the version I am using (3.0.21 on RHEL 9). I have three api calls, to three different url’s, so I figured out how to create multiple instances of the rest module, which is great. It’s just the response logic that I’m failing to understand. Could anyone point me to the right direction? Best, Francis

Using the authenticate function on rlm_python
by Francis Augusto Medeiros-Logeay 16 Nov '24

16 Nov '24

Hi there, I am trying to write a python script to be used by the python module of Freeradius. My main goal is to send an Access-Challenge to the user so that he would reply to that challenge. On perl, usually this «Response-Packet-Type» is configured on RAD_CHECK. But how do we send this in Python? I tried this: def authenticate(p): print("*** authenticate ***") print("") radiusd.radlog(radiusd.L_INFO, "*** log call in authenticate ***") print("") print(p) print(radiusd.config) print("") reply = ( ('Reply-Message', 'Hello from rlm_python'), ('State', 'test'), ('Response-Packet-Type', 'Access-Challenge') ) # config = ( ('Response-Packet-Type' , 'Acccess-Challenge'), ) config = ( ('Cleartext-Password' , '123'), ) return (radiusd.RLM_MODULE_HANDLED, reply,None) But without any success. Any clues of what to do here? Best, Francis -- Francis Augusto Medeiros-Logeay Oslo, Norway

Re: Add TLS version to logs with linelog in FreeRADIUS 3.2.4
by Dominic Stalder 15 Nov '24

15 Nov '24

Hi guys * another try, after failing to reach the mailing list for this topic with my email address * Coming back to this topic of TLS logging in FreeRADIUS 3.2.4, are there any news on this topic? I recently updated to FreeRADIUS 3.2.6, but TLS version is still missing. In the debug output (freeradius -X) I was missing the follwing attributes since 2.3.4: (10) update { (10) &reply::Framed-MTU += &session-state:Framed-MTU[*] -> 1014 ... (10) &reply::TLS-Session-Cipher-Suite += &session-state:TLS-Session-Cipher-Suite[*] -> 'ECDHE-RSA-AES256-GCM-SHA384' (10) &reply::TLS-Session-Version += &session-state:TLS-Session-Version[*] -> 'TLS 1.2' Thanks and regards Dominic

Reject certificate in use
by Rodrigo Prieto 13 Nov '24

13 Nov '24

Hello, I need to configure that if a client's certificate is in use, it cannot be used by another. I was looking at some examples on the web but it didn't work for me. If you can guide me, I appreciate it. Thank you.

logging auth failures with inner identity
by James Potter 12 Nov '24

12 Nov '24

Hi list, I'm working on setting up FreeRad logging and I'm stuck on how to capture the EAP inner identity when an authentication fails. * I can capture auth requests coming in (in authorize section of outer site) * I can capture auth successes and failures (in outer site:post-auth) * I can capture successful auths in the EAP:TLS inner site But - when an EAP-TLS auth fails (eg on cert expired, not trusted, revoked) then it appears that the inner site is not called at all. I've put relevant log lines in TLS-inner:post-auth (and authenticate and authorize) but it appears that none of these are called. Any idea how I can access the inner username (in the case of TLS I'm after the SAN UPN of the client certificate) in a failed auth attempt? Thanks, Jim Potter Jisc Config snippets FWIW: server home { authorize { log_auth_req eap } post-auth { log_auth_accept Post-Auth-Type REJECT { log_auth_reject } } } eap { tls { virtual_server = eap-inner } } server eap-inner { authorize { log_inner } authenticate { log_inner } post-auth { log_inner Post-Auth-Type REJECT { log_inner } } }
