+    When running the publisher in ``handle_errors=False``-mode, which
+    happens for instance when running Grok in a WSGI pipeline with a
+    debugger middleware enabled, we don't want IUnauthorized errors to
+    be reraised during publishing.
+
+    We can indicate this by providing an adapter, that adapts
+    exceptions of this type (`IUnauthorized`) to
+    `zope.publisher.interfaces.IReRaiseException` and returning
+    ``False`` when being called.
