Products.CAS4PAS (buildout) and CAS4PAS (old Zope 2 projects) are
working for CAS2.

Others products are spinoff from them and I don't know which bug they fix.

I don't know anything about the guts of CAS4PAS.  If you think this is a
bug in the sessioning machinery itself, you might try swapping out an
alternate session data manager, e.g. 'faster':

 http://agendaless.com/Members/tseaver/software/faster/

If that makes the problem go away, thenn you could work on trying to
reproduce the problem in isolation.  If not, then the bug is in the
CAS4PAS code itself.

since this presents 2 questions -- I would like to ask more about the first
--

of all the CAS pluggins for zope and plone -- which one works best;-)
Actually, since we serve content both directly from Zope AND from plone, I
need one that works with 'both'... in other words, I need something that
works for zope authentication -- as well as plone. Any pointers on which
'single' prooduct package will allow that?
