WCF - Getting CommunicationException - wcf

Question

I have a WCF service that is providing Authentication/Authorization for a different WCF service.
Here is a sample method:
public int AddCustomerStopInfo(CustomerStop stop)
{
var request = new AddCustomerStopInfoRequest(stop);
var service = new ChannelFactory<IAccountManagementChannel>("WSHttpBinding_IAccountManagement").CreateChannel();
try
{
var response = service.AddCustomerStopInfo(request);
service.Close();
return response.AddCustomerStopInfoResult;
}
catch (CommunicationException e)
{
service.Abort();
throw;
}
}
On the service.AddCustomerStopInfo() method call, an exception is thrown. The message reads:
Secure channel cannot be opened because security negotiation with the
remote endpoint has failed. This may be due to absent or incorrectly
specified EndpointIdentity in the EndpointAddress used to create the
channel. Please verify the EndpointIdentity specified or implied by
the EndpointAddress correctly identifies the remote endpoint.
The server binding for the service looks like:
<bindings>
<wsHttpBinding>
<binding name="WSHttpBinding_IAccountManagement" closeTimeout="00:01:00"
openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard"
maxBufferPoolSize="524288" maxReceivedMessageSize="100065536"
messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true"
allowCookies="false">
<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
maxBytesPerRead="4096" maxNameTableCharCount="16384" />
<reliableSession ordered="true" inactivityTimeout="00:10:00"
enabled="false" />
<security mode="None" />
</binding>
...
<services>
<service behaviorConfiguration="ABCD.Service.Service1Behavior"
name="ABCD.Service.AccountManagement">
<endpoint address="" behaviorConfiguration="ValidationBehavior"
binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IAccountManagement"
name="WSHttpBinding_IAccountManagement" contract="ABCD.Service.IAccountManagement">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="mex" behaviorConfiguration="" binding="mexHttpBinding"
contract="IMetadataExchange" />
</service>
And the client side:
<client>
<endpoint address="[site location]/AccountManagement.svc"
binding="wsHttpBinding"
contract="IAccountManagement" name="WSHttpBinding_IAccountManagement">
</endpoint>
</client>
Both services are on the same server. I don't understand why I am getting this error if the other service has <security mode="None"> ?

As you are trying to use a secure binding via wsHttpBinding you will need to connect to the server via https and use debug code to allow a permissive connection to your test server.
This is because you'll only have a self signed certificate and https is really strict when it comes to security certificates.
