How to deal with switches not sending User-Password attribute for MAC-based authentication
Hi, I'm setting up wired 802.1x authentication for Juniper and Ubiquiti switches. Each device supports supplicant-based authentication and can fall back to MAC-based authentication. When using the Juniper, if it falls back to MAC-based authentication it sends an Access-Request with User-Name and User-Password attributes that both contain the MAC address of the device connecting to the switch, such as "e6e849A201e8". However, when the Ubiquiti falls back to MAC-based auth the Access-Request it sends only contains the User-Name attribute. Since my sites-enabled/default file contains: if (User-Password) { update control { Auth-Type := rest } } in the authorize section, REST authentication is completely skipped. I then tried adding: if (&NAS-Port-Type == "Ethernet" && !User-Password) { update control { User-Password = &User-Name Auth-Type := rest } } right on top of the previous section, but then I get this: (1) if (&NAS-Port-Type == "Ethernet" && !User-Password) { (1) if (&NAS-Port-Type == "Ethernet" && !User-Password) -> TRUE (1) if (&NAS-Port-Type == "Ethernet" && !User-Password) { (1) update control { (1) User-Password = &User-Name -> 'E6E849A201E8' (1) Auth-Type := rest (1) } # update control = noop (1) } # if (&NAS-Port-Type == "Ethernet" && !User-Password) = noop (1) if (User-Password) { (1) if (User-Password) -> FALSE (1) pap: WARNING: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

(1) [rest] = invalid (1) } # authenticate = invalid (1) Failed to authenticate the user (1) Using Post-Auth-Type Reject So I changed it to this: if (&NAS-Port-Type == "Ethernet" && !User-Password) { update control { Cleartext-Password = &User-Name Auth-Type := rest } } (2) if (&NAS-Port-Type == "Ethernet" && !User-Password) { (2) if (&NAS-Port-Type == "Ethernet" && !User-Password) -> TRUE (2) if (&NAS-Port-Type == "Ethernet" && !User-Password) { (2) update control { (2) Cleartext-Password = &User-Name -> 'E6E849A201E8' (2) Auth-Type := rest (2) } # update control = noop (2) } # if (&NAS-Port-Type == "Ethernet" && !User-Password) = noop (2) if (User-Password) { (2) if (User-Password) -> FALSE (2) pap: WARNING: Auth-Type already set.

What would be the best way to deal with the lack of the User-Password attribute? Thanks, -Martin

That's a violation of the RFCs, unfortunately.
Since my sites-enabled/default file contains:
if (User-Password) { update control { Auth-Type := rest } }
in the authorize section, REST authentication is completely skipped. I then tried adding:
if (&NAS-Port-Type == "Ethernet" && !User-Password) { update control { User-Password = &User-Name
Don't do that.
Auth-Type := rest } }
right on top of the previous section, but then I get this:
Where you haven't included the Access-Request packet coming in. How can we help debug things if were don't know what we're debugging?
(1) if (&NAS-Port-Type == "Ethernet" && !User-Password) { (1) if (&NAS-Port-Type == "Ethernet" && !User-Password) -> TRUE (1) if (&NAS-Port-Type == "Ethernet" && !User-Password) { (1) update control { (1) User-Password = &User-Name -> 'E6E849A201E8' (1) Auth-Type := rest (1) } # update control = noop (1) } # if (&NAS-Port-Type == "Ethernet" && !User-Password) = noop (1) if (User-Password) { (1) if (User-Password) -> FALSE (1) pap: WARNING: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! (1) pap: WARNING: !!! Ignoring control:User-Password. Update your !!! (1) pap: WARNING: !!! configuration so that the "known good" clear text !!! (1) pap: WARNING: !!! password is in Cleartext-Password and NOT in !!! (1) pap: WARNING: !!! User-Password. !!! (1) pap: WARNING: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
That's pretty clear.
So I changed it to this:
i.e. "randomly changed things in the hope it would do something". That's not the way to debug or fix issues. The better method is to understand what's going on. And, to understand what you want.
if (&NAS-Port-Type == "Ethernet" && !User-Password) { update control { Cleartext-Password = &User-Name Auth-Type := rest } }
(2) if (&NAS-Port-Type == "Ethernet" && !User-Password) { (2) if (&NAS-Port-Type == "Ethernet" && !User-Password) -> TRUE (2) if (&NAS-Port-Type == "Ethernet" && !User-Password) { (2) update control { (2) Cleartext-Password = &User-Name -> 'E6E849A201E8' (2) Auth-Type := rest (2) } # update control = noop (2) } # if (&NAS-Port-Type == "Ethernet" && !User-Password) = noop (2) if (User-Password) { (2) if (User-Password) -> FALSE (2) pap: WARNING: Auth-Type already set.

Exactly.
Am I approaching the problem in a wrong way? What would be the best way to deal with the lack of the User-Password attribute?
Define "deal with". What do you want to do? What's in the packets? What is the REST API doing? "I want to do stuff" is a request we can't help with. If you want to see if the device is authorized, and only the User-Name contains the MAC address, then look up the MAC address via the REST API. Alan DeKok.
Hi Alan, Thanks for your reply. Full debug is below. I guess I wanted a way for FreeRADIUS to send a request to my REST API and make sure that it was sending the User-Password attribute as well since my REST API expects that field in order to validate it. That REST API is basically a Go micro web server that, depending on the various RADIUS attributes received in the HTTP request from FreeRADIUS, will determine if it's being asked to authenticate an Access-Request coming from the OpenVPN server on pfSense, a Raritan KVM, or a cluster of WiFi APs and then contact the appropriate backend (LDAP server or PostgreSQL server) to make a go/no-no decision. So far I was using this section to redirect auth requests to the REST API: if (User-Password) { update control { Auth-Type := rest } } But from what you're saying I may have been approaching it in the wrong way. Maybe I should stop trying to provide a User-Password attribute to the REST API when there isn't one and should just send all requests to the API server regardless and let it itself handle cases where there is a missing User-Password attribute. -Martin FreeRADIUS Version 3.0.17 Copyright (C) 1999-2017 The FreeRADIUS server project and contributors There is NO warranty; not even for MERCHANTABILITY

I'm setting up wired 802.1x authentication for Juniper and Ubiquiti switches. Each device supports supplicant-based authentication and can
fall
back to MAC-based authentication. When using the Juniper, if it falls back to MAC-based authentication it sends an Access-Request with User-Name and User-Password attributes that both contain the MAC address of the device connecting to the switch, such as "e6e849A201e8". However, when the Ubiquiti falls back to MAC-based auth the Access-Request it sends only contains the User-Name attribute.
That's a violation of the RFCs, unfortunately.
Since my sites-enabled/default file contains:
if (User-Password) { update control { Auth-Type := rest } }
in the authorize section, REST authentication is completely skipped. I then tried adding:
if (&NAS-Port-Type == "Ethernet" && !User-Password) { update control { User-Password = &User-Name
Don't do that.
Auth-Type := rest } }
right on top of the previous section, but then I get this:
Where you haven't included the Access-Request packet coming in. How can we help debug things if were don't know what we're debugging?
(1) if (&NAS-Port-Type == "Ethernet" && !User-Password) { (1) if (&NAS-Port-Type == "Ethernet" && !User-Password) -> TRUE (1) if (&NAS-Port-Type == "Ethernet" && !User-Password) { (1) update control { (1) User-Password = &User-Name -> 'E6E849A201E8' (1) Auth-Type := rest (1) } # update control = noop (1) } # if (&NAS-Port-Type == "Ethernet" && !User-Password) = noop (1) if (User-Password) { (1) if (User-Password) -> FALSE (1) pap: WARNING: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

That's pretty clear.
So I changed it to this:
i.e. "randomly changed things in the hope it would do something".
That's not the way to debug or fix issues. The better method is to understand what's going on. And, to understand what you want.
if (&NAS-Port-Type == "Ethernet" && !User-Password) { update control { Cleartext-Password = &User-Name Auth-Type := rest } }
(2) if (&NAS-Port-Type == "Ethernet" && !User-Password) { (2) if (&NAS-Port-Type == "Ethernet" && !User-Password) -> TRUE (2) if (&NAS-Port-Type == "Ethernet" && !User-Password) { (2) update control { (2) Cleartext-Password = &User-Name -> 'E6E849A201E8' (2) Auth-Type := rest (2) } # update control = noop (2) } # if (&NAS-Port-Type == "Ethernet" && !User-Password) = noop (2) if (User-Password) { (2) if (User-Password) -> FALSE (2) pap: WARNING: Auth-Type already set.

(2) authenticate { (2) rest: ERROR: You set 'Auth-Type = REST' for a request that does not contain a User-Password attribute!
Exactly.
Am I approaching the problem in a wrong way? What would be the best way to deal with the lack of the User-Password attribute?
Define "deal with". What do you want to do? What's in the packets? What is the REST API doing?
"I want to do stuff" is a request we can't help with.
If you want to see if the device is authorized, and only the User-Name contains the MAC address, then look up the MAC address via the REST API.

Actually, my idea to "just let the REST API handle" is pretty ridiculous since right now I can't even get FreeRADIUS to send to REST if I don't have a User-Password attribute: rest: ERROR: You set 'Auth-Type = REST' for a request that does not contain a User-Password attribute! So I guess my request is this: is it possible to get FreeRADIUS to forward requests to the REST module even if the request does not contain a User-Password attribute? If so, how? Thanks, -Martin
hi, well, if you know that only a particular client is doing this, then have a check for that client and if its not got a User-Password set, then set one. then your current call then follows which would work as theres a User-Password as expected etc. alan On Fri, 24 Jan 2020 at 19:02, Martin Gignac <martin.gignac@gmail.com> wrote:

That's what I initially thought of doing by putting (which Alan DeKok later said I shouldn't do): if (&NAS-Port-Type == "Ethernet" && !User-Password) { update control { User-Password = &User-Name Auth-Type := rest } } in the autorize section but I then received this error in the logs: (1) if (&NAS-Port-Type == "Ethernet" && !User-Password) { (1) if (&NAS-Port-Type == "Ethernet" && !User-Password) -> TRUE (1) if (&NAS-Port-Type == "Ethernet" && !User-Password) { (1) update control { (1) User-Password = &User-Name -> 'E6E849A201E8' (1) Auth-Type := rest (1) } # update control = noop (1) } # if (&NAS-Port-Type == "Ethernet" && !User-Password) = noop (1) if (User-Password) { (1) if (User-Password) -> FALSE (1) pap: WARNING: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! (1) pap: WARNING: !!! Ignoring control:User-Password. Update your !!! (1) pap: WARNING: !!! configuration so that the "known good" clear text !!! (1) pap: WARNING: !!! password is in Cleartext-Password and NOT in !!! (1) pap: WARNING: !!! User-Password. !!! (1) pap: WARNING: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! (1) pap: WARNING: No "known good" password found for the user. Not setting Auth-Type (1) pap: WARNING: Authentication will fail unless a "known good" password is available (1) [pap] = noop so I guess I cannot set the User-Password attribute myself. And it appears that the REST module will not fire if I do not have a User-Password attribute set to begin with. Were you proposing something else than what I've tried? Regards, -Martin

You're using the REST module for authentication. There's no need to do that. You can use the REST module for doing *any* REST query.
So I guess my request is this: is it possible to get FreeRADIUS to forward requests to the REST module even if the request does not contain a User-Password attribute? If so, how?
Add a User-Password attribute. The issue is that you're adding it to the "control" list. This is wrong. Add it to the "request" list, so that it's added to the incoming packet. It should then work. Alan DeKok.

Thank you very much for this hint Alan; changing from "control" to "request" was indeed all that was needed for the User-Password attribute to be added and for the REST module to be called. Everything now works. Thank you for your patience, -Martin
hi, would suggest using the unlang man page to read the various list entries such as request (what comes in from NAS and what you need to adjust), control (to instruct the server) and reply (what goes back) alan On Sat, 25 Jan 2020 at 02:47, Martin Gignac <martin.gignac@gmail.com> wrote:

Thanks for the tip Alan B. I did read the unlang man page yesterday, but clearly my understanding of the various lists was flawed. I'm also re-reading https://wiki.freeradius.org/guide/Concepts and it's becoming clear I didn't fully grasp it upon first read. I'm also reading your FreeRADIUS flow document (https://community.ja.net/system/files/257/FreeRADIUS-flow.docx) and that's making realize some stuff. Things are starting to make more sense now. -Martin -Martin On Sat, Jan 25, 2020 at 1:03 PM Alan Buxey <alan.buxey@gmail.com> wrote:
