Sharepoint portal to ActiveX to WebClient back to Sharepoint

Question

Got this problem - not sure if it is possible.

User is logged into the sharepoint portal server.

1. The user opens a page (webpart) in SPS - an ActiveX is started
2. The ActiveX receives data from a docked barcode scanner.
3. The ActiveX creates a WebClient
4. The ActiveX set the credentials on the WebClient as used in point 1.)
5. The ActiveX uses WebClient.UploadFile(..)
6. In SPS an aspx/ascx page recieve the data (as the same user/session in point 1.)
7. Everybody is happy (its friday) - and goes for beer :)

it is the point 4. that is the problem.

Answer 1

It depends on the authentication mechanism used - if the user logs into the page with NTLM (windows integrated), then the WebClient cannot reuse the credentials. If it's kerberos-based, you have a better chance.
