[Zope] exUserFolder and Properties of Users

Hi, I started to use exUserFolder for my site and got a problem with the Properties of Users. I use ZoDB auth Source and ZoDBProperties Source. My question is how to access the Realname and email and phone numbers I can type in the "Add User" form? I already looked a bit through the python code, but did not find something that helped me.
