check if key in self._object_class_keys

[scottcarr]

It's possible for key to be either "objectClass" or b"objectClass". Other places use this self._object_class_keys to handle this scenario.

[graingert]

just above "objectClass" is handled explicitly too, does that need to use _object_class_keys ?

        objectClasses = list(self.get("objectClass", []))
        objectClasses.sort()
        a.append(("objectClass", objectClasses))
