Re: [Zope] user log-ins not persisting

David, I have experienced the same problem. Essentially AUTHENTICATED_USER would waver between the actual authenticated user and the Anonymous User, with no logical explanation for the change. Apparently the problem is related to the HTTP authentication protocol, and some browsers in particular cause this phenomenon. My solution was to use cookie authentication. See the Cookie Crumbler product if you would like to try this. Here is a thread that deals with this problem: http://mail.zope.org/pipermail/zope/2001-November/104827.html Nathaniel
