How to receive the password of the user from a userFolder?
IMO, your best bet is to capture them as you add user objects. Someone else here may have a better answer. Plone has a password retrieval facility, might want to dig into the source and see how it's done there.
The password is stored on a user object as the attribute '__' (that's a double underscore.) Obviously this is not useful to you if you're encrypting passwords. And it must be accessed through file-system code, since it starts with (and is) a double-underscore. There is no standard way to set passwords, btw. Some UserFolders will work if you set __, others require use of some other method. --jcc -- "My point and period will be throughly wrought, Or well or ill, as this day's battle's fought."
