WCF with No security

Question

Hi all,

I've got a WCF service setup which I can consume and use as intendid... but only on the same machine. I'm looking to get this working over multiple computers and I'm not fussed about the security. However when I set (client side) the security to = none, I get a InvalidOperationException:

The service certificate is not provided for target 'http://xxx.xxx.xxx.xxx:8731/Design_Time_Addresses/WcfServiceLibrary/ManagementService/'. Specify a service certificate in ClientCredentials.

So I'm left with:

<security mode="Message">
    <message clientCredentialType="None" negotiateServiceCredential="false"
        algorithmSuite="Default" />
</security> 

But this gives me another InvalidOperationException:

The service certificate is not provided for target 'http://xxx.xxx.xxx.xxx:8731/Design_Time_Addresses/WcfServiceLibrary/ManagementService/'. Specify a service certificate in ClientCredentials.

Why would I have to provide a certificate if security was turned off?

Gives you some more info to go on!!

What's your server side and client side config?? Anything in <system.serviceModel> is of interest. What bindings are you using?

For instance: if you set the client side security to None, you have to do the same on the server side - those settings need to match!

Update:

OK, with the config, I can point certain things out:

<bindings>
   <wsDualHttpBinding>
      <binding name="WSDualHttpBinding_IManagementService" ......>
          <readerQuotas .... />
          <reliableSession ordered="true" inactivityTimeout="00:10:00" />
          <security mode="Message">
              <message clientCredentialType="Windows" 
                       negotiateServiceCredential="true"
                       algorithmSuite="Default" />
          </security>
       </binding>
    </wsDualHttpBinding>
</bindings>

Questions:

• do you really need wsDualHttpBinding? Is that an informed choice?

• if you don't want any security, you need to use:

  <security mode="None" />
  

• you need to have this <bindings> section on both client AND server, and you need to reference that binding configuration from your endpoints:

  <endpoint 
       address ="" 
       binding="wsDualHttpBinding" 
       bindingConfiguration="WSDualHttpBinding_IManagementService"
       contract="Server.WcfServiceLibrary.ICheckoutService">
    <identity>
      <dns value="localhost"/>
    </identity>
  </endpoint>
