Intermediate Certs in EAP-TLS - Confirmed Client-side Problem?
by Aaron Mahler 27 Jun '09

27 Jun '09

Hello! After getting my EAP-PEAP <-> LDAP configuration working this evening, I turned attention to replacing the self-signed certs with our commercial wildcard SSL certificate. This is being used successfully on multiple servers on campus (web, email, etc). It is issued by GoDaddy and does trace back to a valid root cert that I've found exists by default on my OS X systems. The same cert used on our web servers has zero problems and refers to a GoDaddy root. http://www.sbc.edu to see it firsthand. When handed to clients via Radius for 802.1x authentication, though, it's declared as untrusted during the sign-on process. I've seen a few threads on here this evening exploring this very issue (most helpfully from Dan Meyers who describes virtually my same issue). In his case, XP SP2 systems have an issue with it. I can't yet confirm that, but I'm certainly running into the issue with my OS X systems and iPhone. I did a test run on a Unbunu machine a bit ago, though, and it never griped whatsoever. I entered login credentials and it hooked right up. As mentioned above, the cert is a wildcard and identical to the one on our webservers. For comparison, I did a wireshark sniff against our webserver and one of the radius exchange. The cert exchange is identical right down to the byte count. I compared them side by side. In both cases, the full chain from cert through intermediates referring back to the root are being handed over to the client by both Apache and Freeradius. Am I safe in assuming that this is, in fact, a client side problem in the realm of 802.1x implementation and there is nothing I can do on the Freeradius side? Lastly - if there is no way I'm going to get smooth use of a cert involving an intermediate - does GeoTrust still issue root-signed certs as mentioned recently in other posts? Anyone else offer them? Note: I tried to get a free 30-day QuickSSL cert for testing from GeoTrust tonight. Both attempts failed on their end (could not complete my order at this time - no explanation as to why). We'll be serving a large enough user base here that the certificate trust warnings are going to be a HUGE support headache. I need it to be seamless for the end user. Thanks! - Aaron

Definitive Word on FreeRadius/LDAP/EAP Requirements
by Aaron Mahler 27 Jun '09

27 Jun '09

Hello! I've been going in circles - as have many (based on the posts I've read all over the web) - trying to assemble a working combination of Freeradius, Fedora Directory Server (LDAP), and a fleet of wireless access points that seem to want to do EAP. I want anyone with a record in my LDAP server to be able to authenticate via 802.1x from these AP's. The records consist of uid, givenName, sn, mail and userPassword. For starters, I was hoping to just ask a few key questions to try to clear up various contradictory comments I've seen in the zillion things I've read in the last 12 hours: - Is it, in fact, possible to combine 802.1X, EAP, Freeradius and Fedora Directory Server in this manner? - If so (and I'm guessing it is possible), can someone clarify the clear-text vs. encryption issues related to EAP and LDAP? By this, I mean: - Some have said EAP and LDAP can't be combined because LDAP requires plain text passwords here and EAP doesn't play ball in that manner - I've seen conflicting comments on whether the passwords need to be clear-text in my LDAP database or not (or at least how Fedora DS needs to handle its password encryption settings) - Again, if this combination is possible, how far off from a -default- install of the latest Freeradius would the configuration be? It's easy to start making changes to the config and lose your bearings in short order... and, of course, hundreds of lines of debug output scroll by when doing a single 802.1X login attempt. I've repeatedly been able to do radtest checks against LDAP with no problems - but I realize that isn't involving EAP. I just say this to confirm that my LDAP server and Freeradius can talk just fine. I've had no problem with a file-based account with a clear-text password working all the way through the 802.1X process from the AP using EAP. It's when I try to combine the two that things go off the rails. I'll wrap this up with a copy from the debug log of the opening request from an AP in case it helps a bit (IP address xxx'd out in my paste): rad_recv: Access-Request packet from host xxx.xxx.xxx.xxx port 32774, id=6, length=156 User-Name = "ldaptest" NAS-IP-Address = 6.48.0.186 NAS-Port = 0 Called-Station-Id = "00-18-0A-30-00-BA:SBC WiFi" Calling-Station-Id = "00-26-08-62-FD-6E" Framed-MTU = 1400 NAS-Port-Type = Wireless-802.11 Connect-Info = "CONNECT 0Mbps 802.11" EAP-Message = 0x0201000d016c64617074657374 Message-Authenticator = 0x51deb89362f5b9e1c391e88d255eeefa This is followed by the first query (authorize) to the LDAP server happening with TLS mode set to 1 (port 636 - should be a valid SSL conversation) and it binding successfully using an administrative DN. rlm_ldap: waiting for bind result ... rlm_ldap: Bind was successful The account I'm testing (ldaptest) is, for the time being, stored on the LDAP server with a clear-text password due to my questions above. In the test above, I had added: checkItem Cleartext-Password userPassword to my ldap.attrmap. Without that line, the same login test results in: rlm_ldap: performing search in ou=People,dc=sbc,dc=edu, with filter (uid=ldaptest) [ldap] looking for check items in directory... [ldap] looking for reply items in directory... WARNING: No "known good" password was found in LDAP. Are you sure that the user is configured correctly? [ldap] user ldaptest authorized to use remote access rlm_ldap: ldap_release_conn: Release Id: 0 ++[ldap] returns ok The conversation continues on through the TLS segment, offering the example SSL cert to my connecting device (an iPhone talking to the AP in this test), me approving the offered cert on the iPhone and - a moment later - an error that the login/password are wrong. If I start here - with a fresh Freeradius install, references to LDAP uncommented, and basic LDAP parameters properly configured (server, bind dn, base, etc) - could I get some clear points on how to proceed with the configuration? Thanks! - Aaron

Distinguish RADIUS requests from NAS device
by Andrew Hall 26 Jun '09

26 Jun '09

Hi there. We have a network device using FreeRADIUS 1.x for authentication. This RADIUS server in turn queries an LDAP server. We wish to distinguish between "admin" and "login" requests but are struggling to differentiate between the two. At the moment we identify the device by its NAS address but cannot distinguish which type of login request is being made - so cannot then choose which LDAP groups to query. Our only solution so far is to run separate instances of RADIUS and direct the network device to each instance per the request type it receives. Can anyone this of another way to distinguish the requests ? Thanks very much.

Unlang authentication help
by Scott Angus 26 Jun '09

26 Jun '09

hello, I'm trying to use unlang to limit LDAP user's access to different network devices. Here is what I have so far in the site-enable/default: Auth-Type LDAP { ldap if(NAS-IP-Address == 10.1.1.1 && LDAP-Group == 'RouterAdmin') { ok } else { reject } } Right now that works if your LDAP radiusGroupName = RouterAdmin and you are trying to connect to 10.1.1.1 but i would like to add NAS-IP-Addresses and associate them with a radiusGroupName. This is were I'm having trouble. It would be nice it I could just reference a file for the IP's like: RouterAdminList = /usr/local/etc/raddbd/devices/RouterAdmin if(NAS-IP-Address == %{RouterAdminList} && LDAP-Group == 'RouterAdmin') { And have multiple lines.: if(NAS-IP-Address == %{RouterAdminList} && LDAP-Group == 'RouterAdmin') OR if(NAS-IP-Address == %{SwitchAdminList} && LDAP-Group == 'SwitchAdmin') OR if(NAS-IP-Address == %{WifiAdminList} && LDAP-Group == 'WifiAdmin') { ok } else { reject } } How would i do that? And how would list the IP address in the files? Thanks for your help, Scott

RE: EAP-TTLS (PAP) with Win2K3 domain not working
by Petar Marinkovic 26 Jun '09

Thing is that, colleague has a software, developed by his company, I cannot disclose which one, that can test eap-gtc,and that works. And the thing is, when he tries to connect to freeradius server I set up, he cannot auth with domain username and pw. He can auth with EAP-TLS, EAP-TTLS with PAP, EAP-mschapv1 and EAP-mschapv2 and the only thing left to try is EAP-GTC. So my question is, what need's to be done on server side to make that happen? This is server output [eap] No EAP Start, assuming it's an on-going EAP conversation ++[eap] returns updated ++[files] returns noop ++[expiration] returns noop ++[logintime] returns noop ++[pap] returns noop ++? if (!control:Auth-Type) ?

Hi Ivan, All of this is for testing purposes. So, I just need all of those methods to work, if it can't work with domain, then cleartext password will be fine. Can you give me some more info about seting up TTLS-GTC, testing is being done on Windows XP. Also, for EAP-TTLS with chap, enabling user is enough, right?

Huawei WiMax ASN-GW & FreeRadius as AAA
by Paul Carter-Brown 26 Jun '09

26 Jun '09

Hi, I am looking to utilise FreeRadius as the AAA infrastructure behind a Huawei WASN-Gateway on a bleeding edge WiMax network we have implemented for low cost VOIP in Africa. I was wondering if anyone on the forum has experience with Freeradius on WiMax and would be able to help us achieve this on a paid-for basis? Work would be remote via VPN into our infrastructure, or you could join us in Uganda! Let me know if anyone could help with this, or even just point me in the right direction. Unfortunately we don't have capacity in our current team to do this and are looking for someone to jumpstart the effort. Thanks so much Paul CIO Smile Communications www.smilecoms.com

EAP-TTLS (PAP) with Win2K3 domain not working

First, thanks Alan for your help, I managed to make it work with AD. Now I want to try to test to make EAP-TTLS with PAP to authenticate users in domain. I saw this link http://lists.freeradius.org/mailman/htdig/freeradius-users/2008-March/msg00… So I added following lines to modules section of radiusd.conf exec ntlm_auth_pap { wait = yes input_pairs = request shell_escape = yes output = none program = "/path/to/ntlm_auth --username=%{User-Name} --domain=EXCHANGE --password=%{User-Password}" } and I edited /etc/freeradius/sites-available/default file and /etc/freeradius/sites-enabled/default, section authenticate to Auth-Type PAP { ntlm_auth_pap } But when user tries to connect, I get following error: [ttls] Authenticate [ttls] processing EAP-TLS [ttls] eaptls_verify returned 7 [ttls] Done initial handshake [ttls] eaptls_process returned 7 [ttls] Session established.
