Authentication using LDAP for 802.1x
by Marco Streich 22 Jun '13

22 Jun '13

Hi all We have deployed FreeRADIUS on OS X before, but our configuration was rather ugly. What we would do is authenticate users locally, having the machine attached to our OpenDirectory server directly using the Connect Network Account Server functionality provided by OS X. I have seen this question getting asked a lot but still wasn't able to fill my gap in understanding the whole process. We're now using FreeRADIUS Version 2.1.12, for host x86_64-pc-linux-gnu As a start, I'm now trying to get a simple user authentication working. What I have done so far is defining ldap {} in the ldap module and added ldap into the authorize {} section. I also uncommented Auth-Type LDAP { ldap } in the authenticate {} section. <= Bad?! The same for the virtual inner-tunnel. When I run radtest from my laptop, the authentication is successful: $ radtest a4 whatever 192.168.1.231 18120 secret Sending Access-Request of id 18 to 192.168.1.231 port 1812 User-Name = "a4" User-Password = "whatever" NAS-IP-Address = 192.168.17.1 NAS-Port = 18120 Message-Authenticator = 0x00000000000000000000000000000000 rad_recv: Access-Accept packet from host 192.168.1.231 port 1812, id=18, length=20 When I try to authorize a supplicant connected to our switch which is configured to be the authenticator, debug shows me the following: ... rad_recv: Access-Request packet from host 192.168.99.99 port 1645, id=73, length=217 User-Name = "a4" Service-Type = Framed-User Cisco-AVPair = "service-type=Framed" Framed-MTU = 9000 Called-Station-Id = "AC-A0-16-58-EB-07" Calling-Station-Id = "00-23-32-CF-1D-A2" EAP-Message = 0x020b0007016134 Message-Authenticator = 0xa3eaf856385eef096a4a8da0a9b938c3 Cisco-AVPair = "audit-session-id=C0A863630000062C77AFDED6" NAS-Port-Type = Ethernet NAS-Port = 50007 NAS-Port-Id = "GigabitEthernet0/7" NAS-IP-Address = 192.168.99.99 # Executing section authorize from file /etc/freeradius/sites-enabled/default +- entering group authorize {...} ++[preprocess] returns ok ++[chap] returns noop ++[mschap] returns noop ++[digest] returns noop [suffix] No '@' in User-Name = "a4", looking up realm NULL [suffix] No such realm "NULL" ++[suffix] returns noop [eap] EAP packet type response id 11 length 7 [eap] No EAP Start, assuming it's an on-going EAP conversation ++[eap] returns updated ++[files] returns noop [ldap] performing user authorization for a4 [ldap] expand: %{Stripped-User-Name} -> [ldap] ... expanding second conditional [ldap] expand: %{User-Name} -> a4 [ldap] expand: (uid=%{%{Stripped-User-Name}:-%{User-Name}}) -> (uid=a4) [ldap] expand: dc=ldap,dc=hopro,dc=edu -> dc=ldap,dc=hopro,dc=edu [ldap] ldap_get_conn: Checking Id: 0 [ldap] ldap_get_conn: Got Id: 0 [ldap] attempting LDAP reconnection [ldap] (re)connect to ldap.hopro.edu:389, authentication 0 [ldap] bind as / to ldap.hopro.edu:389 [ldap] waiting for bind result ...

Hi Arran, You seem to work 24 hours a day!? Done a git pull, but I think there's some other update that's broken the make, even renaming my local FR git cache and re-downloading (./configure is w/o the securid stuff) I get : CC src/main/radmin.c gcc: error: no: No such file or directory make: *** [build/bin/local/radmin] Error 1 Hmm..

User disconnect
by Dagia Dorjsuren 20 Jun '13

20 Jun '13

Hello, Does anyone know how to solve following issue? In this case : 1. NAS (Chillispot based access point) 2. Freeradius If NAS is shutdowned, the freeradius keeps all user logins of that NAS. In this case, the users session is alive. In fact, freeradius doesn't know if NAS's status is shutdowned or running. Is there any configuration that freeradius disconnects the users automatically when NAS is shutdowned? On the other hand, I would like to terminate the user's session when NAS is shutdowned or unavailable.

Setting VLAN based on ldap attribute id
by Thomas Hermarij Maimann Andersen 20 Jun '13

Hi, I've been reading the mailing list for a few days and tried to see if there are any posts resempling mine. There are a few "almost" but noting that has got me that final step. Currently i have a radius server authenticating with ntlm to an AD. What I wan't now, is to assign a VLAN to the user based on ExtensionAttribute1, which is set to a numeric value which represents the VLAN id. E.g. 1001 I am currently messing with sites-enabled/default in the post-auth section where I try to set Tunnel-Private-Group-Id to the number they have in their attribute, but I have no clue on how to link that. Please help. -- Med venlig hilsen / With best regards Thomas Andersen Systems and Network Administrator IT University in Copenhagen Rued Langgaards Vej 7 2300 København S Phone: +45 72185249 ________________________________________________________________ **NEVER DISCLOSE YOUR PASSWORD OR SHOE SIZE - NOT EVEN TO YOUR DENTIST**

terminate eap-ttls
by adrian.p.smith＠bt.com 20 Jun '13

I have managed to setup a simple test using eapol_test as per http://www.openlogic.com/wazi/bid/188089/Authenticating-Wi-Fi-Users-with-Fr… and it all works as described except that I have to use ca.pem instead of server.pem. I think this might be because the example uses an older version of FreeRadius? What I really need to do is proxy the inner message to another Radius server which will do the authentication but I cannot get this to work. Whatever I try, I always see an EAP-Message avp heading off to the remote server. I have looked at the proxy-inner-tunnel virtual server but am unsure how to use it. Some simple steps would be appreciated. Many thanks in advance.

So the idea is that you have a column in the database that gets update every time you receive an interim-update. If the difference between NOW() and the last update is greater than the interim update interval, then the client has most likely gone offline, and the session can be marked as closed. The extended schema (it's only one more column) and updated queries are in the master branch. You can't copy and paste directly because of the configuration file format changes, but you can just copy the queries across between 3.0.0, 2.0.0 as the schema hasn't changed that much. For closing out stale sessions, as I said, you can run multiple queries (separated by semi colon), so can use accounting packets to trigger the process. Or you can just use cron, and call whatever client binary is appropriate for your database. Do whatever you think is appropriate. Personally i'd go for cron, but some people like to have the server be self maintaining. -Arran Arran Cudbard-Bell <a.cudbardb(a)freeradius.org> FreeRADIUS Development Team
