freeradius with multiple ldap servers
by Sambuddho Chakravarty 07 Jul '08

07 Jul '08

Hello All Will creating multiple instances of the /etc/raddb/modules/ldap1 and /etc/raddb/modules/ldap2 each with different LDAP server addresses and database information work for having a user authenticate against either of the two LDAP servers. By that I mean that say our user 'try' tries to authenticate and sends the radius server an authentication request message, then, by having two files /etc/raddb/modules/ldap1 and /etc/raddb/modules/ldap2 cause the server to connect to both the servers and check for authentication ? If no then can anyone please suggest what is the way for doing this ? Thanks Sambuddho

Radius + EAP-TLS + LDAP
by Paweł Klisiewicz 07 Jul '08

07 Jul '08

Hello! Is it possible to setup EAP-TLS based authentication without using third part CA for signing certificates ? so basically, keep users Public key's (not certificates) in LDAP and make radius to retrieve them from there and authenticate users in this way using just pair of public and private key ? I hope I express clearly what I mean. I am newbie in radius, I did not find any similar topic. best regards Pawel

preproxy_users doesn't filter attributes
by Michael da Silva Pereira 07 Jul '08

07 Jul '08

Hi All, I am wondering if anybody has done this, I'm sure it's actually very easy to do, But I'm just not able to get it done :( I need to filter requests coming from my NAS going to my radius server being forwarded to a clients radius server. Now I am able to modify and update attributes, even add using preproxy_users. but how on earth do I drop the attribute completely? Currently in preproxy_users: DEFAULT Realm == "testrealm.com" NAS-IP-Address := 196.3.121.32, User-Name =* ANY, User-Password =* ANY Other server still recieves: 3GPP2-Correlation-Id Calling-Station-Id Framed-Protocol User-Name User-Password Service-Type NAS-IP-Address NAS-Identifier Proxy-State User-Password Client-IP-Address Kind regards, Michael da silva Pereira

by nf-vale 07 Jul '08

07 Jul '08

Hi all, In my deploy, freeradius is retrieving clients info from sql nas table, but this table does not have a "virtual _server" column, and need to use virtual servers. Is it possible to get "virtual_server" info from sql nas table, instead of clients.conf file. If yes, what do I need to do? Thx, Nelson Vale

RE: freeradius-proxy + PAP works, PEAP and the rest doesn´t
by uni＠christiankraus.de 06 Jul '08

06 Jul '08

Hi, so, I did some new runs. There are no more DH error within the radiusd -X output, but as you already pointed out, the freeradius is acting as proxy. Here is my hardware setup just for clarification: 1. setup: WLAN access router => Aruba WLAN concentrators => IAS/Radius => external RADIUS server What worked: - Login through Web Redirect homepage + PAP + external servers - Login through 802.1X/MSCHAPv2/PEAP for users on the IAS/RADIUS But I couldn´t get external RADIUS server get connected to the IAS/RADIUS with given local login credentials Therefore I tried FreeRadius, which leads to the 2. setup: WLAN access router => Aruba WLAN concentrators => FreeRadius (which proxies to) => Win2003 with IAS/Radius // external RADIUS server I´m still waiting for an answer whether there´s now a succesful request from external server to my local on, What is working: - Login through 802.1X/MSCHAPv2/PEAP for users on the IAS/RADIUS, which are now procied succesfully through the FreeRadius What is not working: - Login through Web Redirect homepage + PAP + external servers So, first get that problem solved: - PAP through IAS/RADIUS to external servers was working - PAP through the FreeRADIUS server to external servers isn´t working So, how to fix this? thanks and a happy weekend

I'm a little stumped as to how to proceed with this (other than going back to 2.0.4), and it's late on a Friday afternoon so I'm going home to think :-) Thanks, John. -- --------------------------------------------------------------- John Horne, University of Plymouth, UK Tel: +44 (0)1752 587287 E-mail: John.Horne(a)plymouth.ac.uk Fax: +44 (0)1752 587001
