Hi !

I need to create my own authentication module to
handle both the Form authentication and the Windows
authentication (Users without the proper windows
credentials will be redirected to a logon page and
will have to enter some alternate credentials using
a login/password validated by a form-like authentication
mechanism).

So far I have been able to create the form authentication
part without too much troubles, but the windows
authentication part is a little more tricky.

Basically what I miss is the user token found in the
request to create a WindowsIdentity object. I know that
the Windows authentication module provided by microsoft
does that by accessing an internal HttpWorkerRequest
object and getting the user token by calling
HttpWorkerRequest.GetUserToken(). Unfortunately I can
access the internal HttpWorkerRequest object.

Any idea on how to get it?

Arnaud :O)

PS: I have a working version of my work at
http://pichery.dyndns.org/aspnet using the provided
Windows authentication mechanism and overloading it
with the form authentication mechanism. But I need to
wrap the whole into a IHttpModule and thus using the
provided Windows authentication mechanism is not an option.
