Description

I have implemented Axis2 web service using Rampart module for username/password authentication. Direct request to the service implementation looks like (header is generated by Rampart, based on WS Security Policy using Password Digest):

<?xml version='1.0' encoding='UTF-8'?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
	<soapenv:Header>
		<wsse:Security
			xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"
			soapenv:mustUnderstand="1">
			<wsse:UsernameToken
				xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"
				wsu:Id="UsernameToken-29057219">
				<wsse:Username>libuser</wsse:Username>
				<wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest">zjSmm202AHSBk2N6gW0bzYjJq8U=
				</wsse:Password>
				<wsse:Nonce>i+46ifpbSz1OHWRL57W0yg==
				</wsse:Nonce>
				<wsu:Created>2009-05-30T12:15:15.703Z
				</wsu:Created>
			</wsse:UsernameToken>
		</wsse:Security>
	</soapenv:Header>
	<soapenv:Body>
		<ns1:NewOperation xmlns:ns1="http://www.example.org/Axis2/">
			<in>TEST</in>
		</ns1:NewOperation>
	</soapenv:Body>
</soapenv:Envelope>

If authentication fails AxisFault is thrown which produces this response to the client (it works correctly):

<?xml version='1.0' encoding='UTF-8'?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
	<soapenv:Body>
		<soapenv:Fault
			xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
			<faultcode>wsse:InvalidSecurity</faultcode>
			<faultstring>The security token could not be authenticated or authorized</faultstring>
			<detail />
		</soapenv:Fault>
	</soapenv:Body>
</soapenv:Envelope>

If I easily add this service to the ServiceMix, fault is not propagated to the client, because ServiceMix throws this exception (servicemix-cxf-bc doesn't work as a proxy only and stops returning response to the client because of exception):

I tried almost all version of servicemix-cxf-bc components (2008.1, 2009.1, last source) with no success.
