[Zope] Zope with IIS using NT security, remote user mode

Hello all: I am wondering if anyone can point me to information about setting up Zope to run in remote user mode. I am trying to get Zope to work with IIS and use NT security. I have followed the documentation but haven't been successful. The only thing I can think of is remote user mode. I am not sure exactly what that is or how to properly set it up. Any help or pointers would be greatly appreciated. Thanks! Michael
