Cannot log into my RADIUS protected wireless connection. Here's the LOG contents

As soon as someone tries to connect to my network, this appears in the log:

Tue May  3 15:58:40 2011 : Error: TLS Alert read:fatal:unknown CA 
Tue May  3 15:58:40 2011 : Error:     TLS_accept:failed in SSLv3 read client certificate A

Tue May  3 15:58:40 2011 : Error: rlm_eap_tls: SSL_read failed inside of TLS (-1), TLS session fails.
Tue May  3 15:58:40 2011 : Auth: Login incorrect: [steve/<no User-Password attribute>] (from client test port 18 cli 0ceee6b55136)

After Googling a bit this seems to be a problem with certificates on the client side, correct?

I'm using FreeRadius.NET hosted on Windows 7 and I'm trying to connect to the wireless network via a Windows 7 client.

After running the application in debug mode and trying again, I get this error. Pardon the screenshot, I cannot copy text in Windows command line.

Am I correct in this assumption that the certificate is the cause of the error? I'm 100% sure that there is a user named steve:

//In users.conf
steve User-Password == "testing"

The server is failing on the client certificate portion of authentication. Here's a how-to from FreeRADIUS on how to set up EAP-TLS, or alternatively you can set it to not require a client cert by setting it for a different EAP mechanism in eap.conf.
