Is there a XLAT IF(..) like expansion?

29 Mar '23

Hello again I'm trying to accomplish the following (pseudo code): In rlm_rest module config: authenticate { body = "json" data = '{ "token" : "xxxxxxx", "states": [ "x", "y" ], "resourceIds: PSEUDO_CODE>> IF(%{control:Cust-Resource-Uuid}, [ "%{control:Cust-Resource-Uuid}" ], null) <<PSEUDO_CODE , }' } I.e. when the custom attribute is set, the JSON's "resourcesIds" property should be an array containing the attribute's string content, otherwise "null". Your help is much appreciated! Cheers, Till

EAP tunnel username problem
by ST Wong (ITSC) 29 Mar '23

29 Mar '23

Hi all, We're running freeRADIUS 3.0.21 for 802.1x authentication. It works all the time. However, we note that occasionally in log entries for successful login, the username logged by default site is different from the real username,e.g. 1. Username changed to "user" while domain part remains unchanged: Wed Mar 22 17:28:20 2023 : Auth: (23249490) Login OK: [skywalker(a)mydomain.hk] (from client ctrl01 port 0 via TLS tunnel) Wed Mar 22 17:28:20 2023 : Auth: (23249491) Login OK: [user(a)mydomain.hk] (from client ctrl01 port 0 cli 67A2ED8ECBAF) 1. First character in username is stripped: Wed Mar 22 15:39:12 2023 : Auth: (23080299) Login OK: [s1234567890(a)mydomain.hk] (from client ctrl01 port 0 via TLS tunnel) Wed Mar 22 15:39:12 2023 : Auth: (23080300) Login OK: [1234567890(a)mydomain.hk] (from client ctrl01 port 0 cli 73D2ED9CABEB) I've no idea as over 99% of the logs look good. Would anyone please help? Thanks a lot. Best Rgds /st wong

Questions about FreeRadius and unsupported characters for secret...
by Tammy Dore 28 Mar '23

28 Mar '23

Hi, We have received a number of issues reported by our customers in regards to the secret authentication does not support certain characters in our software released based on FreeRadius v3.0.19. As a result of this, we had done some of our own comparison testing of a bunch of different special characters against both the v3.0.19 and the v2.2.9 releases. We found the following discrepancies, where it appears that there are bugs introduced into v3.0.19. 1. We would like to understand what explanation there is for why they are no longer supported or if a bug was introduced, so we can offer an explanation to our customers. 2. If there is a work-around, would you kindly let us know? 3. Do you know if these issues have been corrected in one of your newer releases?

LDAPS Unknown error from LDAP module
by Grosjean Cyril 27 Mar '23

27 Mar '23

Hello, I’m using Freeradius 3.2.1 and with a standard config connected to an LDAPS server, some requests (bind as admin, search/bind as user/…) are currently finishing with those kind of errors : Tue Mar 14 03:08:56 2023 : Auth: (43138) Login incorrect (ldap: Failed performing search: Unknown error): [user@domain] (from client XXX port 0 via TLS tunnel) Tue Mar 14 03:30:24 2023 : Auth: (43714) Login incorrect (ldap: Bind with uid=serviceaccount,dc=subdomain,dc=com to ldaps://server:636 <mimestream://server:636> failed: Unknown error): [user@domain] (from client XXX port 0 via TLS tunnel) I can see something like 3 to 5% of requests being made and finishing as “Unknown error”. 1/ Can you confirm that the “Unknown error” is from the LDAP response and not Freeradius ? Can we have more information about status code of the response ? I’m seeing here two occurences of “Unknown error” in the ldap module (ldap.c) but I can’t get more information, and it is hard for me to activate debug that show Radius attribute in stdout (as some of them are sensitive). 2/ Can I activate more debug on thoses errors to get the bottom of it ? Do you have any insight to help me get more information ? Here is my LDAP config : ldap { server = 'ldaps://serverldap.com' port = 636 identity = 'uid=serviceaccount,dc=subdomain,dc=com' password = ‘password' base_dn = 'dc=subdomain,dc=com' update { control: += 'radiusControlAttribute' request: += 'radiusRequestAttribute' reply: += 'radiusReplyAttribute' } user_dn = "LDAP-UserDn" user { base_dn = "ou=users,${..base_dn}" filter = "(uid=%{%{Stripped-User-Name}:-%{User-Name}})" } group { base_dn = "ou=groups,${..base_dn}" filter = '(objectClass=posixGroup)' name_attribute = cn membership_attribute = 'memberOf' cacheable_name = 'no' cacheable_db = 'no' } profile { } accounting { reference = "%{tolower:type.%{Acct-Status-Type}}" type { start { update { description := "Online at %S" } } interim-update { update { description := "Last seen at %S" } } stop { update { description := "Offline at %S" } } } } post-auth { update { description := "Authenticated at %S" } } options { chase_referrals = no rebind = yes res_timeout = 20 srv_timelimit = 3 net_timeout = 10 idle = 60 probes = 3 interval = 3 ldap_debug = 0x0000 } tls { require_cert = 'allow' tls_min_version = "1.2" } 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 retry_delay = 30 lifetime = 0 idle_timeout = 60 } } Thanks, Cyril

Edit User-Name based on regex
by ANGEL LUIS MATEO MARTINEZ 27 Mar '23

27 Mar '23

Hello, I have a scenario where I need to modify User-Name, before any AAA operation, based on a regex substitution. To be precise, the users are sending a MAC as the username, in the form "00:11:22:33:44:55" and I need to transform this to "001122334455". This may be a silly question, but I haven't found how to do it. Is there any way to do it? Thank you. -- Angel L.

Re: Auth failed accounts and write to SQL database
by Steven Walters 24 Mar '23

24 Mar '23

Thanks for the information provided Matthew. I got it working. I have however a slight challenge when trying to set the Class attribute instead of updating the database, as suggested. In the Access-Accept I set the Class attribute equal to reject which works fine in the case where we have our own BNGs. The value I set is the value I receive from the BNG in the Accounting-Start message. However, where we consume network services where we don't use our own BNG, the PPPoE gets proxied to us by the access provider's RADIUS. Whatever value we set in the Class they will encode to hex, add IXX and then encode to hex again. For example, if I set Class = reject, I receive: 0x4958583078373236353661363536333734 When I do string:Class I get: IXX0x72656a656374 Using a calculator, if I convert 0x72656a656374 from hex to string I get the value reject. Using the below I am trying to extract 0x72656a656374 from IXX0x72656a656374 which I write to Tmp-String-2 and then apply string to Tmp-String-3. However I end up with Tmp-String-3 = 0x72656a656374 but would like the original value (reject) I set in the Access-Accept message. if ("%{string:Class}" =~ /(IXX)(0x[0-9a-f]{12})/) { update request { &Tmp-String-2 := "%{2}" &Tmp-String-3 := "%{string:Tmp-String-2}" } }

Questions on Free Radius with Shared Secret and special characters
by Tammy Dore 23 Mar '23

23 Mar '23

Hi, We upgraded from a previous version of Free Radius v3.0.19. Recently we have had some complains that some special characters which used to work in our previous release, no longer work. So far I have discovered that these special characters do not work: , ; ' So which known special characters are not supported? Do I need to use an escape sequence in front of the special character to make it work? I saw a blog that mentioned the correct_escapes setting in radiusd.conf can be used to correct the problem with special characters. So does setting correct_escapes = false, will that allow a secret with "testing123\," to work?

23 Mar '23

Hi All, Which FreeRADIUS attribute I can use to mark the session contains a free data consumption policy, meaning I want to set one attribute with value for the mark session for any reason like free data or expired subscriber. and also want that attribute in accounting packet. Also want to change that attribute value with CoA. Please suggest any attribute that all NAS will supports for CoA as well. Thanks Imdad
