[Zope] cas for zope and plone

I am interesting in integrating cas into my zope and plone sites. I am assuming that cas authentication works fine when zope is proxied behind apache. I thought I better verify that it did though before going to much farther. Is cas for zope working? Does it work when zope is proxied by apache? Are there additional issues for getting cas to work with plone? -- David Bear phone: 602-496-0424 fax: 602-496-0955 College of Public Programs/ASU University Center Rm 622 411 N Central Phoenix, AZ 85007-0685 "Beware the IP portfolio, everyone will be suspect of trespassing"
