4.2.2 Stay Alive Refresh – Search
A search is then made for the specific rtPerson object associated with the registered user. For example:
BaseDN: objectClass=rtPerson, SearchScope: base Object, SearchAlias: neverDerefAliases
LDAPFilter Filter: (&(objectClass=rtPerson)(cn= egruber@contoso.com)(sttl=10))
If the rtPerson is successfully found, the TTL value has been reset.
If the object is not found, then if the client still requires the Person to be registered, it recreates the entry as specified in N-Client Registration with ILS (section 4.1).
