FreeRadius CA Validation Broken 2.4.5
-
@jimp yes I added email to the certificate. I switched back to psk auth for wifi after failing to get the .p12 file to recognize on android and ios. I just wanted to document the issue here as I know most people won't be able to get eap-tls to work on mobile devices anymore, especially with CA validation.

Why is that - because they removed the email that you can just add via SAN? Confused.. The email address has zero to do with eap-tls working..
Are you saying the client can not import the .p12 file? I can for sure fire up a 2.4.5 snapshot and create a CA, create a cert to see if can import it into my iphone.
Leaving email empty in freeradius settings does not work either.
So your saying freerad still looking for this - does not accept it when SAN and that is why you can not setup freerad in 2.4.5 for eap-tls
-
Sorry for being bit confusing.
I have 2 different issues.
Main issue is that I cannot import .p12 on my ios 12.0.1 or Android 9 October update. Windows or Chromebook has no issues.
Second issue is not being able to do CA validation and that is due to email address being no longer supported in the GUI. But freeradius requires email for validation, I guess that is freeradius issue.
Edit: Can a CA have email address via SAN? As far as I can see only email for certs can be added via SAN. If that is the case freeradius is not checking email field properly.If you are going to test on iOS you need to first download the private key and cert and generate .p12 with a password.
-
Yeah I know how to do it ios ;) Been running eap-tls with freerad running on pfsense for a few years..
Have to fire up copy of pfsense on latest snap to give this a go..
edit: ok vm is booting latest 2.4.5 snap.. Will install the freerad package and see what happens.
Ok so when installed freerad it put in its own CA and server cert.. I just created a new one.. And free let me just leave the stuff not using blank.. And didn't throw any errors
-
so far dude not having any issues. Just installed cert signed by CA in my phone without any problems - nothing has any emails on it.
-
That's good that you got it to work. I am going to try again.
-
I won't be able to test it until get home.. But can install the cert, and freerad didn't complain about the CA with only putting in the CN.. Left all the other fields blank.
What openssl cmd you using to add the password?
-
openssl pkcs12 -export -certfile Radius+CA.crt -in sg.crt -inkey sg.key -out sg.p12 -
@johnpoz just tested cert again, this time i didn't enter fqdn/hostname and it worked! I just wish CA validation worked.
-
Have no idea why you say it doesn't are you saying freerad throws error when you enable it - or that you can not auth?? I can not actually test until get home... But freerad doesn't have any problem with me turning on the CA and just putting in its CN.
-
It does not auth, it throws an error that the CA attributes don't match and then prints the attributes it is checking against and the attributes it sees.
-
When does it throw that error - when client actually tries and auths.

maybe empty email should not be treated as admin@mycompany.com

Yeah where did that come from?? is freerad doing that? Pfsense? Just woke up - have not had time to test yet.. Got to change my wireless to point to the new radius server, etc.
edit: Ok yeah this seems to be something with the freerad package.. .Its pulling info that is not there

When I removed freeradius and then CA and all the certs and re-installed it, it auto generated a CA and server cert. Not 100% sure but looks a lot like info in those default certs.
-
yeah I thought I had posted the default certs... Is in the config.. Posted above - but that info doesn't match what is in the default cert created either.
Looking to see now if you man edit the conf if can be a work around.. The package needs to be adjusted to not check for stuff that is not being used.
-
Ok.. If you edit the conf directly and restart freerad it works.

Going to need to file a bug report on the freerad package.. Not sure who maintains that - but maybe @jimp can help.
Thanks for bringing this up - might have gone unnoticed.. Prob not a lot of people setting up eap-tls ;) With new certs.. I prob would fo updated and still be using my certs and ca from before... Which have all that info in there because it use to be required by the gui.. Since the certs good for like 10 years could of gone awhile before changed ;)
edit: I wonder if that gets loaded in by default on package load.. And just doesn't get overwritten when fields are left blank?
-
I think that the values are hardcoded in. I tried entering email and then removing the email with same results.
Do you want me to make a bug report or do you want to do it?
-
There might already be a report of this? Have not had time to check yet. Also be nice if @jimp could chime in on his thoughts on this.. Not sure if he is the specific developer for freerad package - but for sure his insight would be very useful.
But sure go for submitting report - reference this thread for sure.. I also want to take a look at the code for the freerad package.. Might be able to spot where the problem is - that is always helpful in the report. etc.
