1) Does installing PCGI within the iPlanet server guarantees a full one-to-one mapping between iPlanet threads and ZServer threads?

Not at all.

I kind of expected this, but it should not be critical in this first phase.

...

2) Will I be using the REMOTE_USER REQUEST variable or the AUTHENTICATED_USER one?

Unless you can patch the server or compile a special server module, or use a better protocol such as FastCGI, you stuck with REMOTE_USER which is not ideal at all.

Yes, it is not ideal , but it could be workable for our needs (no content delegation and such). Thanks for your answer, Michel.

3) I already installed the iPlanet server and Zope on a Sun. How do i go configuring the iPlanet server in order to activate Zope?

I've not heard of anyone running Zope with iPlanet.

Hey, come on, I am sure I saw someone on this list saying that they installed Zope behind Netscape Enterprise Server, and that's the same beast.

...

Those of you who already accomplished this (and I know you're out there), please speak up!

I HIGHLY suggest you look at FastCGI.

I definitely will, but I guess it will take a little while, so I am postponing it to the second phase of the project. So, doesn't anyone have a nice, step-by-step instruction for setting up the iPlanet (Netscape) server in PCGI mode, or in any other one?
