[Zope] Authentication with IIS

[Ava]

Hello,

This question has been asked several times already, and the answer is always
the same:

Q: How to to interface Zope with IIS
A: turn off challenge/response authentication and turn on basic
authentication for Zope to handle authentication

*BUT* I want IIS to handle authentication, and give Zope the user's name
through REMOTE_USER.
It seems not to be possible. Has anyone managed to do that?

Here, everyone who is logged on the NT Domain is already authenticated when
they browse the intranet. But I don't know how to get this information from
Zope.

*Please* give me any clue concerning this.
<PROMISE>
If someone can point me in the right direction, I can even start to write
some code because my boss is not willing to use basic authentication.
</PROMISE>
