I purchased a certificate from digicert to use for our 802.1X wireless network. I have setup a Server 2012 R2 NPS and added the cert to the server, but both my Windows and my OSX clients still display a message to accept the certificate. I have checked the cert store on the Windows Clients and the digicert root ca cert is there as it is included on all windows clients with recent updates installed.
I have tested this on OSX Lion and Windows 8.1. I am about to test it on a Windows 7 machine as well.
I needed to use a public CA certificate because we are a college campus and we have students who bring their own devices I don't have control over so I can't use Group Polices to push our MS certificate to them.
This seems like it should just work with the public CA cert. Any ideas why it isn't just trusting the certificate? I have also been trying to find some logs to determine where it denies the certificate but I don't see anything for that.
