[Zope] Using WebServerAuth

[Shane Voss]

I am trying to bring up-to-date an existing Zope set up running on an obsolete 
version of Zope.  I am trying to get WebServerAuth to work for me as it seems 
to be the obvious replacement for the home-grown system in place on the 
exiting server.

So far, I have been unable to make it appear in the Products list.

I changed my  buildout.cfg  and the Product now appears in the  eggs  folder 
of my Zope installation, but not in the ZMI Control Panel

I found (and set) in zope.conf:  enable-product-installation on
So I know that a number of other products are bring installed.

I tried adding a suitable link in the Instance Products directory.
That resulted in  "module not found"  errors leading me to install additional 
Products (PluggableAuthService and CMFCore) and to link those in to the 
Products directory too.

I have now reached impasse with  CMFCore complaining:

    from zope.globalrequest import getRequest
       ImportError: No module named globalrequest

I have found and installed (with buildout) the  zope.globalrequest  egg, but I 
can't work out how to bodge any links to make things work.

So...

Can anyone tell me how to install this Product ?
(All this is being done with  Zope2-2.13.18 )
