Client Certificate and Code Access Security

Discussion in 'ASP .Net Web Services' started by Jürgen Laude, Jan 13, 2005.

  1. Hi,

    I am implementing a IIS deployed client (Windows Forms) that accesses a web
    service on the same server. I want to use client certificates for
    authentication.
    My problem is, when I call the web service with CAS "Internet" permissions,
    I'm receiving a SecurityException in a thread that seems to create the
    connection. The user selects the certificate with a OpenFileDialog configured
    for working with "Internet" permissions. I can verify the loading of the
    certificate and assigning it to the web service proxy works without problems.
    Running the same with "Full Trust" works perfect, but my customers require
    "Internet" permissions only.
    What do I need to do to work arround that? If not, why is using a client
    certificate that the user manually selects a security risk (it is no problem
    for Internet Explorer to do that)?

    Thank you in advance,

    Jürgen
