[Zope] User Authentication

Hi, soon I have my examination and I must program a product and I will program it with Zope. And for my product I need a User Authentication, I can use the acl-user folder but I must have the e-mail address of the registered user and with the acl-user folder I don´t get the e-mail addresses! Is there an another way? I won´t use CMF I need only the Authentication with E-Mail Address. Thank you for the Answers! :) Regards Steven
