Yes. Yes and steep.

Zope has its own authentication/session management built in. You will see this when you set up your first Zope and go to manage something. There are a few products out there that let you create better login/user management as well as some that you can connect to SQL databases or LDAP. A new product in the works it the PTK (Portal Tool Kit) that will have a lot of this built into it. My suggestion: Start poking around Zope.org, read up on the stuff there and download and install Zope. That will give you a better idea of what you are dealing with.
