Introduction

This is not the quickest possible install but rather a step by step water proof install.

You should end with an empty plone site on which you can log-in using CAS

Requirements

This procedure is based on a linux/Unix environment but is easyly reproductible on win2k
This install was done with these versions and suppose you know the basics of zope installation and ZMI

• python-2.4.3 with SSL support (to allow https acces to cas server)
  to check ssl support type
• python
• import socket
• hasattr(socket, "ssl") => should be true
  
• zope-2.9.6
• plone-2.5.2-1
• cas4pas-1.0.0-1 + patch provided on this site
• plonecaslogin-2.5.0
  

The procedure was successfull with other mix of versions of zope and plone 2.5.x < 2.5.2

Install Plone on a fresh instance

After installing zope and creating an instance

• Stop Zope
• install the Plone products in the folder $ZOPE_INSTANCE/Products
  you should end with something like :
  /var/www/zope/yourinstance/Products/Archetypes
  /var/www/zope/yourinstance/Products/...
  /var/www/zope/yourinstance/Products/CMFPlone
  
• Start zope and check the event log for missing python libraries
  /var/www/zope/yourinstance/log/event.log
• Check also the ZMI for Broken products in
  /Control_Panel/Products/

Create a Plone site

Now from the ZMI add a "Plone site" from the root folder
Let's call it yourplone, we'll use the default settings
Base Profile: Plone site

Now we should have a functional Plone site writable with your admin user.

Install CAS4PAS + patch

Now download the official cas4pas-1.0.0-1 product and the patch provided on this site

• stop Zope
• install cas4pas into
  /var/www/zope/yourinstance/Products/CAS4PAS  (case does matter, and remove version number from the folder name too)
• apply the patch :
  cd /var/www/zope/yourinstance/Products/CAS4PAS/
  gunzip -c  /tmp/CAS4PAS-1.0.0-cas2.patch.gz | patch -p1
  
• start Zope again
• Check like previously the eventlog and from ZMI the CAS4PAS Product

Install PloneCASLogin for Zope

download ploneCASLogin

• stop Zope
• install PloneCASLogin into
  /var/www/zope/yourinstance/Products/PloneCASLogin/  (case does matter, and remove version number from the folder name too)
• start zope
• Do the same checks as previously from eventlog and ZMI

Install PloneCASLogin for Plone

Log-in as admin on your plone site (not on ZMI) which may be accessible from
http://your_server:8080/yourplone/

• go into site-configuration -> Add / suppress Products
• Install PloneCASLogin
• In case of problem, be sure to install the missing python libraries (and ssl python support) and restart Zope before retrying this step.

Now you should have a CAS-login environment set up automatically

Configure your CAS URL's

Last but not least, you have to set up your CAS login/logout/service URL's

• go to ZMI into
  http://your_server/yourplonesite/acl_users/plonecaslogin/
  Note: plonecaslogin has been created by PloneCASLogin Install
• use the "propertiers" tab
• now fill with the correct URL's

If everything went well (usually it does ;-) ), you can now use CAS login
