EAP-TTLS tunnel
by Sergio Belkin 05 Dec '07

When using EAP-TTLS the tunnel is between Access Point and client only? I mean: Is it protected data between AP and freeradius? Thanks in advance -- -- Open Kairos http://www.openkairos.com Watch More TV http://sebelk.blogspot.com Sergio Belkin -

Oracle LDAP and password
by Fabio Pedretti 05 Dec '07

05 Dec '07

I am using FreeRADIUS 1.1.7 and I want to authenticate my users against an Oracle LDAP. TTLS-PAP works fine, but I also need PEAP-MSCHAPv2, so I have to be able to read NT-LM password. I noticed that the Oracle LDAP server stores password in this format: authpassword;orclcommonpwd: {X- ORCLLMV}708090a0b0c0d0e0f000102030405060 authpassword;orclcommonpwd: {X- ORCLNTV}000102030405060708090a0b0c0d0e0f I verified that the the LM and NT hashes match those needed by FreeRADIUS but hashes are after a special header ({X- ORCLLMV} or {X- ORCLNTV}) and all in the same attribute (authpassword;orclcommonpwd). Is it possible to configure FreeRADIUS to read the hashes in these format? Thanks, Fabio

authentication by DHCP-request
by Thorsten Leiser 05 Dec '07

05 Dec '07

Hi, we're just implementing port security with freeradius 1.1.6. For our XP-Boxes we'll use the built in 802.1x-supplicant. But there are some dumb thinclients without any supplicants available. Fortunately, we're able to modify the User Class option (option 77) within the dhcp-request of these thinclients. So, we're trying to authenticate the clients by using the modified dhcp-request. Do you have an idea how we can use this modified dhcp-request to authenticate angainst our radius server? Or any other idea?

problem with attributes in access-reject
by Rob Mason 05 Dec '07

Freeradius version:1.1.8 with jradius Hi I am trying to send some attributes in an access-reject message , viz: User-Name: value 'echoed' from Access-Request Service-Type: 1 (Login-user) Reply-Message: Wrong user name or password However freeradius appears to be blocking all but Reply-Message from getting to the client. I can see these being set in the output of my jradius going towards the free radius server, however I am only seeing Reply-Message in the reply coming to the client (User-Name and Service-Type come through OK on my Access-Accept case). Attached are attrs config file and radiusd Output from jradius: ================ --- packet 2 of 2 Class: class net.jradius.packet.AccessReject Attributes: User-Name := bill Service-Type := Login-User Reply-Message := Wrong user name or password Output from Freeradius ================= modcall[authorize]: module "jradius" returns reject for request 11 modcall: leaving group authorize (returns reject) for request 11 Invalid user: [bill@AMMEON/billpass] (from client local port 1819 cli 0851234567) Delaying request 11 for 1 seconds Finished request 11 Going to the next request --- Walking the entire request list --- Waking up in 1 seconds... --- Walking the entire request list --- Waking up in 1 seconds... --- Walking the entire request list --- Sending Access-Reject of id 32 to 127.0.0.1 port 32796 Reply-Message := "Wrong user name or password" Output to client (pyrad): access denied Attributes returned by server: Reply-Message: ['Wrong user name or password'] Rgds Rob Mason This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.

Server 1 will send an "Access-Accept" packet and the switch enables the port. Then if server 1 goes down and you attempt to reauthenticate the port, the switch tries server 2. That is when it fails. When I tested this the first time, authentications to server 1 worked and to server 2 did not. When I couldn't figure it out, I turned the test machines off and left for the day. The next day I had server 1 turned off - I turned the test machines on and authentications to server 2 worked fine, but would not work on server 1 once I powered it on. The common denominator here was that authentications work against the first server it tries but not any others. That's why I postulated that there must be some sort of session resumption going on. >> Is there a way to tell FreeRadius to tear down the session >> once the user has been authenticated so that the next authentication >> will work if using a different server?

Was a shot in the dark based on some googling I had done awhile back.

That's how I've been testing it and it's not working, see above description. If I run the servers in debug mode (radiusd -X) the output starts to get different at line 420 of the middle of the conversation. The working server waits 6 seconds and then continues processing the next Access-Request packet: (Note that these servers are in a test environment, so there are no additional access-request packets reaching the servers, just the packets from the testing machine) Finished request 0 Going to the next request --- Walking the entire request list --- Waking up in 6 seconds... rad_recv: Access-Request packet from host 172.22.30.170:1812, id=29, length=171 NAS-IP-Address = 172.22.30.170 NAS-Port = 50016 NAS-Port-Type = Ethernet ...... while the non-working server cleans up the request, then receives an Access-Request packet: Sending Access-Challenge of id 37 to 172.22.30.170 port 1812 EAP-Message = 0x011300061920 Message-Authenticator = 0x00000000000000000000000000000000 State = 0x466470a3816b19a56b24e71b7dff8089 Finished request 0 Going to the next request --- Walking the entire request list --- Waking up in 6 seconds... --- Walking the entire request list --- Cleaning up request 0 ID 37 with timestamp 47556860 Nothing to do. Sleeping until we see a request. rad_recv: Access-Request packet from host 172.22.30.170:1812, id=38, length=171 NAS-IP-Address = 172.22.30.170 NAS-Port = 50016 NAS-Port-Type = Ethernet ..... I can send the debugs in their entirety if you would like but thought I'd keep them off the list for now. What else could be going on here? Thanks for looking at this, if I can send you anything else please let me know.

Configuring LDAP for query ONLY...
by Eric Martell 03 Dec '07

03 Dec '07

I am little bit confused as how to configure radiusd.conf in the authorize and/or authenticate section. So password is going to act like ldap attribute. We are going to pass, username and ldap attribute (home phone #) as input for each user. The way it is configured now is in the modules, ldap { server = "10.11.12.2" identity = "cn=Manager,dc=eng,dc=com" password = answer2 basedn = "dc=eng,dc=com" filter = "(&(uid=%{Stripped-User-Name:-%{User-Name}})(phone=1231313128))" // just for testing ldap_connections_number = 5 timeout = 4 timelimit = 3 net_timeout = 1 } authorize { .. .. .. ldap ... } authenticate { Auth-Type LDAP { ldap } } In the logs it says: rlm_ldap: - authorize rlm_ldap: performing user authorization for test1 radius_xlat: '(&(uid=test1)(phone=1231313128))' radius_xlat: 'dc=eng,dc=com' rlm_ldap: ldap_get_conn: Checking Id: 0 rlm_ldap: ldap_get_conn: Got Id: 0 rlm_ldap: attempting LDAP reconnection rlm_ldap: bind as cn=Manager,dc=eng,dc=com/answer2 rlm_ldap: waiting for bind result ... rlm_ldap: Bind was successful rlm_ldap: performing search in dc=eng,dc=com, with filter (&(uid=test1)(phone=1231313128)) rlm_ldap: looking for check items in directory... rlm_ldap: looking for reply items in directory... rlm_ldap: user test1 authorized to use remote access this is good.... But in the authenticate section rlm_ldap: - authenticate rlm_ldap: login attempt by "test1" with password "1231313128" rlm_ldap: user DN: id=1967816, dc=eng,dc=com rlm_ldap: bind as id=1967816, dc=eng,dc=com/1231313128 rlm_ldap: waiting for bind result ... rlm_ldap: id=1967816, dc=eng,dc=com bind to 10.11.12.2:389 failed Inappropriate authentication rlm_ldap: ldap_connect() failed Not sure why it is trying to bind as id=1967816, dc=eng,dc=com/1231313128 The only thing I want to do it, just authorize the ldap and pass the user through. Please let me know if I am missing something. Thanks so much. Regards, Erik. ____________________________________________________________________________________ Be a better sports nut!
