FreeRadius and WPA2-Enterprise machine authentication - With ActiveDirectory interconnection..

[Tim Reimers]

Thanks Max and Alan --

Can someone point me to the best and newest documentation to use in setting this up?
I see docs that refer to Freeradius 1.X and 2.X, but I'm not sure if everything in those is accurate for 3.0

thanks, Tim

As I understand it, when you configure 802.1x authentication on Windows, provided you tick the relevant box, Windows will authenticate twice, using the computer account and then the user account. Only after that does domain authentication direct to a DC kick in. It is possible to omit either stage, but I think only group policy can force use of the computer account only

I wouldn't contradict anything others have said about this one, they know their stuff more than me, but we *sort of* do this - user auth using 802.1x plus mac address auth with macs stored in AD. Most wireless controllers I've seen will support 802.1x + MAC , and do it as 2 separate authentication transactions. Some will also let you decide the order the transactions appear in. 
Mac auth isn't great on its own, but in addition to 802.1x you are authing the user/whole computer with certs and the computer with mac addresses.
Just my 2p, possibly off track or wrong practice though!

Hi everyone - 

I'm trying to design something here that I'm sure has been done before, but AFAIK, it crosses through a few different howto documents, and being new to this, I'm just not certain that I have pieced together all the relevant HOWTo docs and not missed a point at which the design won't communicate the needed information.

The plan is to authenticate wireless users AND their computers. (so that a user cannot BYOD to the secure network; only laptops joined to the domain will work)

I know that WPA2-Enterprise is what I need, to be able to have rotating keys, use Radius for authentication, etc.
I know that WPA2-Enterprise requires certificates to validate the machines

I already have a Microsoft CA server running in my AD environment, with the GPO needed to push out workstation certificate enrollment and so on, for other applications.

My question is -
Can FreeRadius (3.0.1) on centos 7
be configured to do the machine authentication using certs from the Microsoft CA server?
Meraki is the wireless infrastructure, if that helps.

Thanks, Tim
