No, not there. I thought that the exception happens in

    def post_callback(self, ldap, dn, entry, *keys, **options):
        try:
            self.obj.add_aci(entry)
        except Exception:
           ...

Ah, sorry, I think I mislead you with this advise. You probably could use the
same except clause as already used:

            except errors.NotFound:
                raise errors.ValidationError(
                    name='ipapermlocation',
                    error=_('Entry %s does not exist') % location)
