def add_to_cache(self, dn, marker):
        """
        Add the entry to the app cache. It will be automatically removed after ``timeout`` seconds.
        If an entry for ``dn`` (with any marker) already exists, it will be overwritten.
        Keep in mind that removal will then provoke a "Removal from app
        cache failed: ... mapped to ... " log message!
        If an entry for ``dn`` with the same marker exists, the eviction timeout will *not*
        be extended if it is added again.
        This function respects the ``case_insensitive`` option.
