Working on a WCF service with transport security using client certificates for credentials, I came across this error today:

“The SSL settings for the service ‘SslRequireCert’ does not match those of the IIS ‘Ssl’.”

Having figured out what the issue is, now the message is obvious but before I had the solution, google search lead me nowhere. I finally figured it that IIS’s default setting for handling client side certificate is to ignore them. Once I changed it from “Ignore” to “Accept”, the service started working.

As a recap here is the simplified configuration of the service:

<serviceHostingEnvironment aspNetCompatibilityEnabled=”true”/>
<service name=”MyServiceName” behaviorConfiguration=”ServiceBehavior”>
<endpoint address=”” binding=”basicHttpBinding” bindingConfiguration=”AuthenticatedSoap11Binding” contract=”IMyServiceContract” />
<binding name=”AuthenticatedSoap11Binding” transferMode=”Buffered”>
<security mode=”Transport”>
<transport clientCredentialType=”Certificate” />

Here is a screenshot of the Setting in IIS:
