Set up Windows Radius Server.

http://www.wikidsystems.com/support/wikid-support-center/how-to/how-to-configure-ias-to-support-two-factor-authentication

I am looking at the link above.
In our environment we have 2 domain controllers. I wan to set up IAS as Radius server and set  up VPN appliance as Radius client.

I want user authentication to be validated by our domain controllers DC1 and DC2.
I wonder whether by ,just authorizing RADIUS server in AD will do the job, or I need somehow to individually add DC1 and DC2 to Radius server.

Any help will be very much appreciated.

Thanks

the link provides setting up a radius Proxy to forward authentication requests to other Radius Servers - as a security measure. Most likely you wouldn't need that.

Authorizing the Radius server in AD will read users properties for both servers, so if DC1 is down - they still can authenticate using DC2

Yes, you don't need to install the RADIUS service on a DC, but you can if you want to.  As long as the server where you install IAS/NPS is a member-server on the domain you want to authenticate users in you will be fine.

And don't install two radius servers. Apparently there are special things you have to do if you want more than one to keep them in sync.

...all you need to do is configure one server how you want it then export the AAA config using NETSH, then import into the second RADIUS server.  It's not a problem.  It's actually advisable to have more than one RADIUS for redundancy.

I think the issue I personally experienced was the lack of 3rd party trusted certs for those servers, so it was easier to just use one radius server in my environment.

You could have still used two RADIUS servers if you issued a cert to each IAS from your internal PKI.  I suspect you were using self-signed certs in your scenario?

Don't want to take over this question with my details, but basically radius2 (on dc2) was not authenticating anyone. I read about cert stuff and just killed it. radius1 is my dc1 anyway and it's a small office so if dc1 goes out I've got bigger problems.
