My Problem: I want to do an UserAuthentication against a Database. I want the Users to set up their own accounts with parameters. 1. Should I do it with the Zope User Mechanism? And if I choose this how can I implement that. 2. Or should I do it with my own User Database authentisation. And how can I do it that way? I tyed 2.) I did a login screen. There the User can input his login and pwd. Both are checked against the DB. And I know if the user is valid or not. But what do I need to do than. I tryed: <dtml-if "pwd==xpwd"> <dtml-call "REQUEST.set('AUTHENTICATED_USER.getUser()','vinox_user')"> or without the ".getUser()" but it didn't worked. And I tryed to logout the User with setting back the <dtml-call "REQUEST.set('AUTHENTICATED_USER.getUser()','Anonymous User')"> Any solutions?
