WCF TransportCredentialOnly not sending username and password

Question

I have the following WCF client configuration:

<basicHttpBinding>
   <binding name="basicHttpOCCWS" closeTimeout="00:01:00" openTimeout="00:01:00"
                 receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false"
                 bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
                 maxBufferSize="100000000" maxBufferPoolSize="524288"
                 maxReceivedMessageSize="100000000" messageEncoding="Text"
                 textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true">
      <readerQuotas maxDepth="32" maxStringContentLength="8192"
                    maxArrayLength="16384" maxBytesPerRead="4096" 
                    maxNameTableCharCount="16384" />
      <security mode="TransportCredentialOnly">
         <transport clientCredentialType="Basic" />            
      </security>
   </binding>
</basicHttpBinding>

In code, I am setting the username and password as follows:

client.ClientCredentials.UserName.UserName = _cacledUserId;
client.ClientCredentials.UserName.Password = _cachedPassword;

However, the web service running on Tomcat is returning an error:

"An authentication object was not found in the security context."

When I look at the HTTP header, it is missing credential information as shown below:

POST /occ600webservice/services/OCC_WS HTTP/1.1
Content-Type: application/soap+xml; charset=utf-8; action=""
Host: 192.54.173.130:8080
Content-Length: 2223
Expect: 100-continue

Why are my credentials not being sent?

TIA.

For others who run into the same problem, wrap each call to the secured web service resource like this:

var client = new WCClient(); 

using (OperationContextScope scope = new OperationContextScope(client.InnerChannel))
{
   var httpRequestProperty = new HttpRequestMessageProperty();
   httpRequestProperty.Headers[System.Net.HttpRequestHeader.Authorization] = 
     "Basic " + 
     Convert.ToBase64String(Encoding.ASCII.GetBytes(
            client.ClientCredentials.UserName.UserName + ":" +
            client.ClientCredentials.UserName.Password));

   OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] =
               httpRequestProperty;

   client.DoSomething();
}
