IIS authenticated SOAP Webservice

How can I authenticate to a web service hosted in IIS that is secured with Integrated Windows Authentication?

Do I use HTTP headers to add username and pwd?

I am trying to call this web se开发者_JAVA百科rvice from UNIX in C.

I'm rather a newbie to IIS myself, and I'm just starting to dance around this topic, but I saw your note and thought it was crazy that no one has answered in so long!

I believe that the typical way that windows authenticates is Kerberos. You may have to go through some gyrations to get the Windows Kerberos server to get you a ticket that you could put in the SOAP header. That is at least the direction in which I would start researching... but it could heavily depend on your Windows domain configuration. At the very least, you'll probably need to do quite a bit of poking into Windows Domain configurations and concepts.
