Credentials across multiple web service boundaries

[Bil Simser [MVP]]

Hi guys,

I wanted to ask some experts here on a problem someone presented to me.

Given a client that's calling a web service (using default credentials) the
web service gets invoked fine with the users credentials. However they need
to call a second web service from the first one. When it hits the second web
service, the web service (even though configured correctly) always reports
as IUSR (or sometime IWAM, or whatever the anonymous accounts are).

Is there a problem trying to do something like this? Is there something
anyone can point me at to try out or a workaround? Thanks.
