HTTPS/SSL Error: Listener was denied access to service wm.server.soap:envelope

I have a web service (provided on IS) that works on a non-encrypted port, but I am trying to restrict access to it by requiring clients to present certificates. The client is not receiving a response and I am seeing the following in the server.log file:

2010-10-21 09:47:55 EDT [ISC.0039.0001D] POST /soap/default

Any ideas on what I need to do to get past this error?

Thanks in advance,
Chris

The issue was resolved by adding the wm.server.soap:envelope service to the list of allowed services for the SSL port.
