Authentication problems depending on connection type
Hello- I am using FreeRadius to proxy connections to an OTP server for a WiFi solution. It looks users up in LDAP and if they exist proxy’s the password in clear text to the Radius server. I am testing on a Cisco WLC and using a Meraki device in production. Not ideal for identical testing I know its buts all I have. They are pointing to the same radius/ldap server. I have things working as long as I am using the Meraki “splash page” to have users authenticate against. I just keep the network open and they connect to the network to authenticate. The problem is the login page comes up but is not consistent. I would rather have my users authenticate with the OTP when joining the network via the OS. With MAC’s this takes a custom profile. In order to do that I have to send the passwords in the clear so I am using PAP-TTLS in the configuration utility to create the profile. If I use the splash page on the open network on the Meraki the access-request looks like this (with a User-Password field): Sending Access-Request Id 211 from 0.0.0.0:39633 to 94.143.115.73:1812 Acct-Session-Id = '569705352865660562' Called-Station-Id = '00-18-0A-32-AF-AA:company Devs' Calling-Station-Id = '14-10-9F-E1-B0-D3' Framed-IP-Address = 10.197.125.204 NAS-Identifier = 'Cisco Meraki cloud RADIUS client' NAS-IP-Address = 108.161.147.80 NAS-Port = 0 NAS-Port-Id = 'Wireless-802.11' NAS-Port-Type = Wireless-802.11 Service-Type = Login-User User-Name = 'haydn' User-Password = 'r4ffev' Event-Timestamp = 'Oct 22 2014 22:23:15 UTC' Message-Authenticator := 0x00 Proxy-State = 0x32 Waking up in 0.1 seconds. When I do it on the WLC with the OS network level connection I get this: Sending Access-Request Id 123 from 0.0.0.0:58776 to 94.143.115.73:1812 User-Name = 'alexgregory' Chargeable-User-Identity = 0x00 Location-Capable = Civix-Location Calling-Station-Id = '78-31-c1-be-89-a8' Called-Station-Id = 'd4-a0-2a-15-7f-00:C2_8021x' NAS-Port = 4 Cisco-AVPair = 'audit-session-id=0a210082000009be54483291' NAS-IP-Address = 10.33.0.130 NAS-Identifier = 'isewlc' Airespace-Wlan-Id = 6 Service-Type = Framed-User Framed-MTU = 1300 NAS-Port-Type = Wireless-802.11 EAP-Message = 0x0201001001616c6578677265676f7279 Message-Authenticator = 0x40c1f142e786e20cf3836cfe05549f35 Event-Timestamp = 'Oct 22 2014 22:41:38 UTC' Proxy-State = 0x3137 Waking up in 0.3 seconds. My question is am I using the same radius config sections when I connect via the OS dialog? What could cause the change on how things are forwarded from the FreeRadius server? It looks like it does EAP which I do not want it to do. (full config and authentication below) Thanks, Alex root@radius:/etc/init.d# /usr/local/sbin/radiusd -X radiusd: FreeRADIUS Version 3.0.4, for host x86_64-unknown-linux-gnu, built on Sep 25 2014 at

So you want to use EAP.

My question is am I using the same radius config sections when I connect via the OS dialog?
Yes.
What could cause the change on how things are forwarded from the FreeRadius server?
The end system sends different information to the NAS. The NAS sends different information to the RADIUS server. I think you're confused about how things work, and what you want the server to do. You probably need to start over. In short, authenticated WiFi uses EAP. You can't change this. Alan DeKok.
Thank you, Alan. I am learning the protocols. A little more each day. I was under the impression that, with EAP, it encapsulates the password in the EAP transmission. If I can only do EAP, then that means it can never send it in the clear. Which means, if I want to send the radius server the password in the clear (since its OTP) what I am doing can’t be done. Is this correct? Thanks, Alex

No. EAP-TTLS uses EAP, TLS for security, and sends a PAP password inside of the TLS tunnel. So the password is in the clear. Alan DeKok.

Alex, When you receive an EAP access request, FreeRADIUS will pass the request on to the 'inner-tunnel' server (defined in /etc/raddb/sites-available/inner-tunnel). If you have an OTP server, you can then proxy the inner tunnel request to the OTP server. Of course, you then lose any of the protection that EAP-TTLS provides, but then again, if you're using PAP only, all bets are off anyway.

Thank you, Stefan. This sounds like what I want to do. Since I am using OTP, passwords sent in clear text are ok (and required by the upstream OTP radius server). I hade the proxy setup, but it sounds like I need to figure out how to proxy just the inner tunnel request. I will check the inner-tunnel config even deeper and see what I can come up with. If you have any tip’s I am open. ;) Thanks, Alex
