freeradius / eap-tls / Android 13

@johnpoz Well then, if basic constrains is already included... :/

@furom but possible android 13 is looking for it elsewhere? Not really an android guy, but you should be able to check on your tablet if it trusts this CA, you should see it in your user section of trusted CAs - like the 2 I have installed.

I have a few different CAs, one for home that I create certs for stuff like my nas, my printer, my pfsense gui, my switches gui's etc..

I also have another one for openvpn, and then the one I created for freerad use.

If you don't see it there - then yeah its highly unlikely that it would trust the cert your freerad server presents, etc.

But its possible wifi stuff using its own settings? Like said not an android guy, notice it doesn't show my homeca as possible ca for my wireless?

So for wireless you might have to install the CA under the wireless settings, but I would think if you have it installed and shown under your user for the system that using the use system certs should work.

I tried using "system" in wifi and didn't work - I have to select the CA I installed using wifi

It is possible of course. It has never been this troublesome ever before, that is for sure...

I will try the separate radserver once more. I just realized I did not install its server cert etc as also is needed...

I'd rather not go the acme way, I don't want nor need the domain... Sad it must be a requirement, it is so close (and will probably just work) but still so far away... :)

This has nothing to do with it.. Your device needs to trust the CA that you sign the freerad server cert you are using in the freerad setup.

And the freerad server needs to trust the client cert the client presents.. Be that freerad running on pfsense or not would have have nothing to do with your client trusting the CA, or presenting the correct cert that the freerad server will accept.

If you can not get the CA installed on your tablet, or be able to set not to validate it - its not going to work. I believe later versions of android removed that option, which people are complaining about since they are having a hard time getting the CA actually installed as well..

I am not having this issue, as you can see I can install CAs under the wifi setting.. But if you miss a step your going to have a bad day.. Your freerad server should have the same CA, and a server cert you created. Your client needs to trust the CA and present a cert also signed by the CA.

Make sure you have fqdn set for the CN..

You are right of course... I'm just sad I can't get this to work... And by the looks of it, by design, so not likely to suddenly start working in a later version... :(

johnpoz

@furom Or your just missing a step? Or forgetting to set fqdn? I wish I had a android 13 to test with.. I hope my son's is running newer version on his phone - if he doesn't come over on monday for bbq, next time he comes over I will be sure to test.

Maybe take a few days off from this.. Just use wpa3 personal for now.

@furom Something like this might be a short-term solution...
https://forum.xda-developers.com/t/samsung-galaxy-tab-a8-2021-sm-x200-android-12-android-13-treble-flash-guide.4497299/
to downgrade to v12... but really don't want to mess with it already...

And even then, I would want to use Samsung official software, which I doubt is made available...

Yeah, WPA3 is working at least, I must be happy with that... And you have gone to lengths to try, I really appreciate that!

I am still intrigued by the Jenkins error though... Why would freeradius/pfSense or openssl try to read anything from such path, that isn't even on the system? Makes no sense either...

furom

@furom Well... couldn't leave it be... :) So I disabled scrubbing in pfSense and bumped fragment_size in freeRadius to 1500, and well, it's still not working, but different song, not sure if better though

This is all of it though, and tablet shows no error, just hangs a few seconds until it times out. What "No EAP session matching state" means... A thread talking about the same error it was high server load, not the case here though; freeradius is running in a VM with almost idle CPU's and lots of memory - it should not complain about that part at least

Hey, I have a free radius server that support eap tls 1.3.
I send an eap tls authentication using Windows 11 and see by wireshark that packet are really eap tls 1.3.
but then when i do it using MacOS / iphone / android that support eap tls 1.3 by default (as wrote in apple and android forums) i see an Client hello of 1.2 without the extension of support version and the authentication is by eap tls 1.2.
Anyone saw this issue/ know if they are really support authentication of eap tls 1.3 ? I use same certificates for all of the clients and install them.
Thanks, Nir.
