Hi, I'm currently doing exactly the same thing :)
(user management with z3c.form, and the class for my users derives from 
zope.app.authentication.principalfolder.InternalPrincipal )

I'm not sure this is a good idea to have "password_confirm" in the interface, 
because it would mean that your user has two passwords (from an interface 
point-of-view). The password confirmation should just be part of the form 
validation. Maybe you have to manually add a field in the form (I'm just going 
to try that).
If you really want to have both password in the interface, you have to implement 
both attribute, and the password_confirm can just be a property whose 'get' 
retrieves the password and whose 'set' just checks that the value (that should 
actually be a hash) is the same as the 'password'.
