401 1 5 - web service refusing access

[pkermeen]

Hi,
I'm having trouble getting a .net 1.1 web site calling a .net 2.0 web
service to impersonate the calling client.

I'm using
WebServiceProxy.Credentials =
System.Net.CredentialCache.DefaultCredentials

And the web sites are both using integrated windows authentication,
with Anonymous access switched off.

Both web server and web service have

<authentication mode="Windows" />
<identity impersonate="true"/>

Set in the web.config

Both sites are using App pools that use the IWAM account, who is
allowed to do impersonation.

The web service log shows:
2006-11-15 10:49:20 W3SVC1169898807 172.16.45.169 POST /Service.asmx -

401 1 5
when the call fails. The 401 5 is an ISAPI/ CGI authorisation issue i
think, so it looks like the web site is not passing the appropriate id
when challenged.

The web server is showing my id when i ask it:
_userID = context.User.Identity.Name; so it appears to be using
impersonation....

Any ideas?

Have you tried using this?
WebServiceProxy.PreAuthenticate = true;
