Description
The password validator UserAttributeSimilarityValidator is currently too rigid and allows comparison of the password only to the fields of the User model, while ignoring the common case where there is also a profile attached to the user (as a separate model). My suggestion is to relax the attribute resolution so that also fields defined on related models could be accessed; for example, by traversing a dotted path as in reduce(getattr, path.split('.'), obj).
Yet a better option could be to allow plugging into the validator by means of an overridable method get_user_attribute(self, attribute_name) used instead of a direct getattr, that will allow more customisation while leaving the validation logic intact.
