3.2 Timers

The ILS Server maintains an entryTTL attribute. This attribute has a value that is a TTL marker for dynamic objects. An LDAP search request for the attribute "sttl" (name mapped) in the form "sttl=<value>" resets the timer to the given value. If the timer goes to zero, the dynamic entry MAY be removed from the database by the server. Client applications need to perform occasional refreshes of the attribute value to ensure that the server maintains the dynamic objects.

An ILS client maintains a timer that mirrors the value sent to the ILS Server. The client MUST refresh the TTL value of dynamic objects. If, on a refresh search, it fails to find a dynamic object, the client MUST register the dynamic object.
