Question

I am getting following error in my web service when using x509 Certificate to authenticate the client.

X509Certificate2 Clnt = new X509Certificate2 (HttpContext.Current.Request.ClientCertificate.Certificate);

The error is
System.Web.Services.Protocols.SoapException: Server was unable to process request. —> System.Security.Cryptography.CryptographicException: m_safeCertContext is an invalid handle.
at System.Security.Cryptography.X509Certificates.X509Certificate.get_Issuer()
at Service.HelloWorld() in c:\MyWorkSpace\SecuredWS\App_Code\Service.cs:line 40
— End of inner exception stack trace

Can any one put some light on it as why i am getting m_safeCertContext as null.
