WCF custom certificate validation with BasicHttpBinding
- by Sprklnh2o
I have a WCF application hosted on IIS 6 that needs to
Have 2-way SSL authentication
Validate client certificate content with some client host information
Validate client certificate is issued by the valid subCA.
I was able to do 1) successfully. I am trying to achieve 2) and 3) by following this - basically creating a class that inherits X509CertificateValidator and overriding the Validate method with my own validation implementation(step 2 and 3). I followed the MSDN instructions exactly however, it seem that the Validate method is not being called. I purposely throw a SecurityAccessDeniedException in the overidden Validate method and no exception is thrown when I tried to access the service via my browser. I can still access my website with any client certificate.
I also read this thread but it didn't really help. Any help would be greatly appreciated!
Here's my configuration:
<system.serviceModel>
<services>
<service behaviorConfiguration="SimpleServiceBehavior"
name="SampleNameSpace.SampleClass">
<endpoint address=""
binding="basicHttpBinding"
bindingConfiguration="NewBinding0"
contract="SampleNameSpace.ISampleClass" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="SimpleServiceBehavior">
<serviceMetadata httpsGetEnabled="true" policyVersion="Default" />
<serviceCredentials>
<clientCertificate>
<authentication certificateValidationMode="Custom" customCertificateValidatorType="SampleNameSpace.MyX509CertificateValidator, SampleAssembly"/>
</clientCertificate>
</serviceCredentials>
</behavior>
</serviceBehaviors>
</behaviors>
<bindings>
<basicHttpBinding>
<binding name="NewBinding0">
<security mode="Transport">
<transport clientCredentialType="Certificate" />
</security>
</binding>
</basicHttpBinding>
</bindings>
