The built-in UserFolder has such a feature:

  When you define a user with empty password and domain restriction,
  then requests coming from this domain are associated with this
  user provided it provides the required roles.

This feature is now disabled by default but can be enabled on
an instance base (look at the code, for details: --> "AccessControl/User.py").

This will not work (easily):

  Roles are managed by the User object.
  A User object is only created after traversal finished,
  there is not yet a User object when AccessRules are executed.
