WSIT/Metro doesn't understand Security SOAP header

Question

I'm using WSIT/Metro to create a simple web-service. I'm getting the following error on the server when a client tries to connect with a simple username/passowrd authentication scheme:

2010.03.31. 19:10:33 com.sun.xml.ws.protocol.soap.MUTube getMisUnderstoodHeaders
INFO: Element not understood={http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd}Security

I have no idea how to make WSIT understand the Security block.

The request I get from the client:

<?xml version="1.0" encoding="http://www.w3.org/2003/05/soap-envelope" standalone="no"?>
<soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope"&gt;

            </wsse:UsernameToken>
        </wsse:Security>

        <wsa:Action>urn:hasCallPolling</wsa:Action>
    </soapenv:Header>
    <soapenv:Body />
</soapenv:Envelope>
