Fixed Impersonation vs Current login user

[Roan Schuurman]

I have a ASp.NET application which performs a http request to another
web site on the same server but different virtual directory. when i
set impersonate = true and a fixed account, the http request is done
with that account. when leave the account blank (current login user)
then the request fails because he has no account. integrated
authentication is on, on both virtual directories.
please some help!

regards,

You have a double-hop authentication issue I think.

With IWA, IIS doesn't have the user's username/password - only a token,
which isn't sufficient to construct a new HTTP request passing credentials.

I think you'll need to configure delegation. Here are some links:

Thanks for your reaction Ken!
Unfortunatly a already had configured everything for delegation but
forgot to mention it. so it still doesn't work.
I also do think it is "double hop" issue, because when i change to
Basic authentication it will work. I don't know how to fix the double
hop issue.
is you have suggestions, please let me know because i am stuck.
