[Zope] ldapuserfolder

The Ldapuserfolder is so sweet! (using it to authenticate against local AD) Only thing I need (or havent figured out) is: How can one assign roles to single users? Is it possible? I'm trying to make some sort of "hompages" where each user have access to and read/write permission to her own folder, but I am only able to assign roles to groups and not to individual users. Best regards Einar
