ldap_exop_refresh — Refresh extended operation helper
Performs a Refresh extended operation and returns the data.
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.
