    positive-time-to-live is the number of seconds after which a cached entry is removed from the cache. This defaults to 3600 seconds (i. e. one hour).
    whereas -
    negative-time-to-live - If an entry is not found by the Name Service, it is added to the cache and marked as "not existent". This option sets the number of seconds after which such a not existent entry is removed from the cache. This defaults to 20 seconds for the password and host caches and to 60 seconds for the group cache.
