FreeRadius PAP authentication for Non-EAPOL clients on Avaya 5500 switch.
Hello, We have been running our radius servers for some time now and they work just fine authenticating our wireless users against our LDAP tree etc. Now my management has asked me to spend some time setting up radius authentication for wired outleds in the office, and for the workstations I got it working rather quickly using EAP-TLS and certificates signed by the same CA that signed the radius certificate. But I also need to accommodate telephones and printers and they don't do EAP themselves. To work around this, the switches we use have an option to configure the switch in such a way that it creates a radius access request based on the MAC address of the client, it's own IP address and the port the client is connected to. You then have to add this information to the users file of the radius server and you should be able to authenticate the device and open the port. This sounds like a simple setup, just add some users with plaintext passwords and start the authentication process. But the problem is that this fails, and it looks like the switch is sending 2 exactly the same authentication requests short after another, and the first one succeeds, but the second one fails. I also see this when I ping the host, I receive one reply and after that the port is closed again. Could someone tell me if I have something wrong in my config? Thanks a lot.

That’s a stupid idea. But I’m not surprised. Vendors are often bad at RADIUS.

No. The User-Names are different. Reading the debug log carefully is important. Also, you should fix your LDAP infrastructure. The server is getting redirected to 3-4 different LDAP servers. That’s slow and inefficient.
I also see this when I ping the host, I receive one reply and after that the port is closed again.
Could someone tell me if I have something wrong in my config?
You need to add the second User-Name to the users file. The first one ends with “20”. The second with “22”. Alan DeKok.
The day after I posted this message I indeed found out that I had read over the MAC address a hundred times without noticing the difference.

a) make the devices do 802.1X b) make the port not do 802.1X c) give up. Pick one.

Ok.. it’s not redirects, but multiple group comparisons (or something similar). v3 should be able to be more efficient than that. Alan DeKok.
Ah, ok. That makes more sence. I match some groups to set specific settings. At the end of all the matches I want to set a default reject. Is the following in the users file correct: DEFAULT Auth-Type := Reject Jan Hugo On 03/01/2015 10:37 PM, Alan DeKok wrote:

There isn't one. The issue with using the MAC as a credential is that the credentials for getting on to your network is *literally* stuck to the side of the device for everyone to read (and can be sniffed in seconds using a tap). It's worse than having open ports, as you end up believing that because you have dot1x on all edge ports you have better security, and also costs you time and money to administer. Put anything that can't do dot1x in an isolated part of the network and use something like PVLAN.

I know the issues with MAC authentication. The solution Avaya gives us is the best thing we have at the moment for these devices. At least it locks a MAC address to a specific port on the switch and any other port you try the MAC address on will block. And for our company is not very big we think that the changes of anyone hijacking a MAC address on the fixed network in one of the work area's is very small. And the problem is on the agenda, so anything new we buy in the future will not have this problem. Jan Hugo On 03/01/2015 10:37 PM, Adam Bishop wrote:

or work in an enterprise environment and realise you cant just do things like that ;-)
Precisely. Real networks - like real security - are full of compromise, ideally based on an evaluation of cost-benefit. Manually patching thousands of 802.1x-incapable devices to separate switches, and manually maintaining the VLANs on those ports, is not a sensible decision for most organisations. The huge overhead this places on adds/moves/changes, the need to purchase and maintain infrastructure, the cognitive costs involved in dealing with separate infrastructure... the list goes on. In an ideal world, we'd all be using 802.1x on the wired side, it would be immune from a layer2 MITM attack, and it would be using a sensible EAP method, which could provision and update credentials in-band. In the real world, hardly any printers or SCADA devices do 802.1x, wired-side 802.1x can be trivially MITM without MACSEC, and the EAP method all suck. So, people look at the situation and make the quite reasonable decision to just use MAC "auth" and be done with it. And you know what? It works pretty well for extended periods of time, and they conclude - quite correctly - that the additional cost of wired 802.1x provides little additional benefit. It's not like we're all doing authenticated DHCP - so we're all doing "mac auth" in some form....

I’m inclined to make FreeRADIUS just start doing authenticated DHCP by default. i.e. if you do 802.1X and then DHCP, the server will add authentication options to the packet. That’s the simplest way to get these things deployed. Alan DeKok.

I didn't think any clients supported authenticated DHCP? Has this changed?

No. But perhaps public shaming would be useful. If FR puts the authentication option in, then people will start talking about it. And realize just how easy it is to do. Alan DeKok.
