Hello,
I'm triyng to use my domain controller (win2008 r2 standard)  as radius server with my AP Cisco ap541n.

On my DC  I configured NPS, but it doesn't work. Microsoft told me that I need a "third part certificate" on my server. Is it true? Where can I buy it?

Thanks for your support

you do not need a 3rd party certificate on your Radius. Do you have an internal PKI solution ?

You might want to put a certificate on you NPS server to make sure clients authenticate to the correct NPS sever and not a fake server (man-in-the-middle attack)
If it doesn't work - look in Security logs and look for failures ---

That is a spot on step by step blog.

Just remember to uncheck the "less secure authentication methods" in NPS server

You should have a certificate for NPS server, but without - just use EAP-MsChap

NAP - CAn also do health check on clients and enforce policies, like if you have outdated AV, they can put you in VLAN 12 which only have access to AV update servers, and when AV is updated you're moved to VLAN 10 which is corporate network

Hello to everybody,
I'm having some issues about CA.

Before migrating to Win2008 I used IAS on Win2003 without certificate. My colleague was able to connect automatically when logged in the domain, and inserting domain user and password using a pc not in the domain.


Do you have a guide for implement a Radius server on a domain controller without using CA???

Is it dangerous in your opinion??

Tnx in advance for your support.
