Getting 401 when using client certificate with IIS 7.5
- by Jacob
I'm trying to configure a web site hosted under IIS 7.5 so that requests to a specific location require client certificate authentication. With my current setup, I still get a "401 - Unauthorized: Access is denied due to invalid credentials" when accessing the location with my client cert.
Here's the web.config fragment that sets things up:
<location path="MyWebService.asmx">
<system.webServer>
<security>
<access sslFlags="Ssl, SslNegotiateCert"/>
<authentication>
<windowsAuthentication enabled="false"/>
<anonymousAuthentication enabled="false"/>
<digestAuthentication enabled="false"/>
<basicAuthentication enabled="false"/>
<iisClientCertificateMappingAuthentication enabled="true" oneToOneCertificateMappingsEnabled="true">
<oneToOneMappings>
<add enabled="true" certificate="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"/>
</oneToOneMappings>
</iisClientCertificateMappingAuthentication>
</authentication>
</security>
</system.webServer>
</location>
The client certificate I'm using in my web browser matches what I've placed in the web.config. What am I doing wrong here?
