    certificate is required to complete client authentication

    Hi



    We have two server SSL certificates from Thawte. We set up these two SSL in
    the same server.



    Now, we want to access a web service hosted by one of our customer in their
    server. We are calling this web service from a web service deployed in our
    server. The customer web service can be accessed only through SSL. They are
    also using Thawte SSL certificate. They sent their client certificate to us
    in p7b format and we installed it in our server (since our web service which
    calls their web service is deployed in our server). When we try to call
    their web service we are getting the error 'A certificate is required to
    complete client authentication' . We use Microsoft .Net for developing our
    web service.



    We then created a sample application in another machine and tested. We
    installed the client certificate sent by our customer in this machine. But
    we again got the same error.



    We tried to access the web service from Internet Explorer. Then it shows a
    dialog box 'Client Authentication' and asking us to select a certificate.
    But there are no certificates listed for selecting

    thanks in advance

      Re: certificate is required to complete client authentication

      Have you verified that it was installed correctly, and is available on the
      user profile in question? If so, it should show up in IE.

      Have a look at mmc.exe / Certificates to make sure it is available and that
      the private key was installed.

      Further, make sure the user has access to the private key (file security).
