hi folks, we are building an application that needs more information for users than that which is made available via the acl_users db (which can only contain username, password, domains, and roles). specifically, we have created an RDBS database which tracks users via a numeric user id (and speeds lookups), all tables are related via this integer variable. we are having difficulty, though, in that, zope continues to want to build a new user entry only via acl_users. has anyone done something that will allow us to get around this. i have been searching all the various search engines and zope list archives looking for something along these lines, and i find a lot of stuff on how zope authentication "out of the box" works though nothing on how to get the authentication to work via another means. i suspect it might require some editing of the base python code, but i am hoping that this can be done from within the Products directory and not in the preconpiled code. any insights would be greatly appreciated. thanks. ciao! greg.
