Hi,
This problem seems to exist on a specific server. All other servers are working ok.
Background: The website is basically Forms Auth but there's an asmx that manually requires Basic Auth.
I have two C# client.
1. When invoking using SOAP (asmx client proxy) with basic auth credentials - all is well.
2. When invoking using WebClient or WebRequest with the same basic auth credentials, I get 401.5.
3. The folders have "Everyone" set to them.
When setting up iis trace, I see a very weird behavior. The request arrives with the correct Basic auth header. But further down the trace I see the following:
GENERAL_REQUEST_HEADERS
Headers="Connection: Keep-Alive
Content-Length: 68
Content-Type: application/json
Authorization: Kerberos
Expect: 100-continue
Host: 1.2.3.4
The Kerberos seems very weird. It is as if the request headers changed throughout the process, and perhaps that explains the 401.5.
Again, I would like to stress out that on other servers there's no problem with both clients. The only difference I can think of is that the problematic server is a DC. But if that is a problem then why is the SOAP client working well?
Any ideas?
