Webservices X509 with Client Certificates

Dear All,

I am developing a web application in .net that needs to serve clientes that has X509 certificates . my webapp needs to call remote webservices from another provides (government servers) that uses the x509 authentication.

I already developed and tested the page using a certfiicate store in the local system using the call below

GovernmentWebservice.ClientCredentials.ClientCertificate.SetCertificate(StoreLocation.LocalMachine, StoreName.My , X509FindType.FindBySubjectName,"MY CERTIFICATION SUBJECT NAME");

But this becomes a problem because I need to use the certificate sent by the client when he connected to my webpage (Request.ClientCertificate.Certificate). I found that the call of the remote webservice only works with certificates stored in my local machine. Anyone knows any workaround so I can use my clients certificate to call the other webservice????

Thanks,
