I have a plone site that serves on http://my.domain.com:8080/intranet.
Based on the plone docs I have a rewrite rule so to translate that ugliness to http://my.domain.com I have cas enabled on the plone site for authentication and it works fine.
Several pages at the root level are available to public unfortunately. So to protect these pages via cas, I have installed the mod_auth_cas in apache.
Now the pages that were previously public are protected by cas, but if I try to go to the root site http://my.domain.com/ I get a redirect loop that keeps generating tickets and goes between cas and my.domain.com trying to validate.
here is my apache conf:
<VirtualHost *> ServerName my.domain.com
<Proxy *> Order deny,allow
Allow from all
