[Zope] Zope and php authorization

[Chris Herrnberger]

Greetings 

Im at a disadvantage here as Im new to zope programming. What I would like to 
accomplish is to integrate in one zope site three existing php applications 
and one zope app that Im just completing. I dont need to have the php tree in 
zope but I do need to have the main site page secured via a logon prompt and 
have the same cookie or session authorize the user for access to the existing 
php applications. I have spend a day reading notes on zope.org on how to 
authenticate users in zope but there seems little relevance to existing 
applications (php or other). 

Can anyone point me to the appropriate references or perhaps possibly comment 
on the best methods to accomplish this integration/authorization exercise.

Best and many thanks
