something along the line of the code below should do the trick (untested):

  from cubicweb.web.views import authentication

  class MyLoginPasswordRetriever(authentication.LoginPasswordRetriever):
    def authenticated(self, retriever, req, cnx, login, authinfo):
        """callback when return authentication information have opened a
        repository connection successfully. Take care req has no session
        attached yet, hence req.execute isn't available.
        # for the reason explained in the docstring, using req.user is not an
        # option and cnx.user() probably not a good idea
        cu = cnx.cursor()
        if cu.execute('Any G WHERE U in_group G, G name "managers", U login %(l)s',
                      {'l': login}):
          raise authentication.AuthenticationError()
  def registration_callback(vreg):
    vreg.register_and_replace(MyLoginPasswordRetriever, authentication.LoginPasswordRetriever)
