NPS Client / Server Certificate Authentication Issue
Posted on 2013-06-23
I've got a tricky issue with NPS (i believe) that is causing my wireless clients to display a warning when connecting to my wireless network. A brief overview of the setup is as follows.
2 X Server 2008 Domain Controllers
1 X Certificate Authority Server
1 X NPS Server with XYZ connection policy
HP Procurve MSM Controller with various AP's all configured in NPS
We had an issue a few months back whereby under NPS
> Network Policies > "Wireless Policy" > Constraints > Authentication Methods
> Microsoft Smart Card of other Certificate"
...The certificate would be issued to a wildcard certificate. When i changed it back to a local CA issued certificate, clients could authenticate again.
This had only happened once to date so i ignored it...til now.
The same thing has happened again, so i changed it back.
Now, when i connect on a client however, i'm getting the error
"The Server XYZSERVER is not configured as a valid NPS server to connect to for this profile"
I can still connect, but i have too many users on this network that will complain about the extra step. I'm confident i can answer any questions you ask me, i know i mightn't have explained myself enough. I've attached a screen shot to see if there is anything immediate that might be causing the issue
Thanks guys and gals.
