Thanks for the quick reply. I've actually done clean builds and the problem persists. I think I am missing some critical pieces here dealing with WS-SecurityPolicy for NtlmAuthentication that arise from the WCF's binding. Using either clientCredentialType="Ntlm" and clientCredentialType="Windows" does not work and CXF complains about having no assertion builder for the corresponding types.
Since then I've attempted to use the WCF Express Interop library at: http://wcf.codeplex.com/wikipage?title=WCF%20Express%20Interop%20Bindings http://wcf.codeplex.com/wikipage?title=WCF%20Express%20Interop%20Bindings and tried to use the wso2InteropBinding and metroBinding but both does not seem to work. With wso2InteropBinding and clientCreditialType="Windows" the assertion builder was looking for NtlmToken and it failed on that. Now I'm trying to see if the code at http://svn.apache.org/repos/asf/cxf/sandbox/interopfest is going to be any help but I have not yet found an example that works against Windows/NTLM authentication, which is what I'm looking for. -- View this message in context: http://cxf.547215.n5.nabble.com/NTLM-security-between-WCF-and-CXF-tp4763671p4775972.html Sent from the cxf-user mailing list archive at Nabble.com.
