Sonsider a 3-tier system: Web browser, Web Server and SOAP service.
Web Server invokes a SOAP service on behalf of some Web users.
There are several issues around user authentication and server-to-server
authentication.

The question around user authentication is that how to carry user's
authentication information for the SOAP call. This is important for
the SOAP services that require users to be authenticated, and/or its result
varies for different users. Personal stock quotes could be  an
example of  such SOAP services.

To avoid service attack etc, SOAP service needs to reject calls from
untrsuted parties. So, the basic quetsion around server-to-server authentication

is that  how a SOAP services know whether it's called from a trusted server.

I'm sure that there are many other issues around security. Without understanding

such issues and appropriate solutions, it's hard for SOAP to be widely adopted.
