[Zope] installation of zope 2.6.

I have the following problems: I have installed Zope 2.6 which is on Linux Suse 8.2 with the installation tool of Linux. With python zpasswd.py inituser I have set users (this was done when I was logged in as root). When I give in the browser: http://localhost:8080/manage I get the login page for Zope, but when I login the it outputs the failure that I have no authorisation (when I was logged as user who I have created before). Can you help me, please? wbr Ali
