[Zope-dev] Security Management

Hi all, I have a question on the security system of zope. First i have a folder called foo in the root with acl_users and a doc called foo_doc: root/ bar_doc foo/ acl_users/ joe foo_doc If Anonymous users could'nt view the foo_doc. This means only logged in users like joe could wie the foo_doc. Now my question is: When joe is logged in in foo to view the foo_doc, and after that he view bar_doc he is authenticated as Anonymous in the bar_doc REQUEST (right??). But is there a way to find out that the current REQUEST comes from joe and joe has no user object in the root acl_users. I played with getSecurityManager, but it doesn't work Can anybody help please as
