User Authentication with FreeRadius and Active Directory - possible?

FrankoniaDKB

Hello,

I am currently testing pfSense 2.4.4 and did also install FreeRadius3.
I did some testing, but unsuccessfull.

I am not sure, if what I want to achieve is possible, or even recommended. Maybe there is also another way to do it better. I appreciate any input.

What I want:
I would like to use a RADIUS Server in my network for authentication of users in our Wireless Network.
We are running a Windows Active Directory Domain. So the best way for me, would be to authenticate the users with the AD.

In my tests, I got it to run successfully (NTRadPing), but only without CHAP.
Group membership checks also work fine.

Whith CHAP, or with a Windows-Client (WiFi Connection) it will not work.
FreeRadius complains about a non clear-text pasword.

So my questions are:

Is it possible to authenticate users with FreeRadius on pfSense with Active-Directory?
Does pfSense need to be Domain joined in some way?

Maybe there is a better way. All I want is users beeing able to use their domain user/pw to authenticate with out wifi APs. I wanted to use this on pfSense, because without it, our VLANs dont work anyways.
Thanks in advance.
