dndn of the entry to refresh.
ttlTime in seconds (between 1 and 31557600) that the client requests that the entry exists in the directory before being automatically removed.
   From RFC:
   The responseTtl field is the time in seconds which the server chooses
   to have as the time-to-live field for that entry.  It must not be any
   smaller than that which the client requested, and it may be larger.
   However, to allow servers to maintain a relatively accurate
   directory, and to prevent clients from abusing the dynamic
   extensions, servers are permitted to shorten a client-requested
   time-to-live value, down to a minimum of 86400 seconds (one day).
   false will be returned on error.
