Right. This is the "baroque" registration API and deprecated in Zope
3.3/the trunk (in the future, please state which Zope version you're
using...)

IComponentRegistry is implemented by site managers. So you should be
able to go the site manager of your nearest site and simply say:

  >>> sm = site.getSiteManager()
  >>> sm.registerUtility(principal_folder, IAuthenticatorPlugin,
  ...                    "cs_users")

zope.traversing.api.getSite gets you to the nearest site, for example.
