Memory Concerns

The entries passed to the search entry callback function do not need to be freed. If you need to access an entry after returning from the callback function, call slapi_entry_dup() to make a copy.

The referral URLs passed to the referral entry callback function do not need to be freed. If you need to access a referral string after returning from the callback function, call slapi_ch_strdup() to make a copy.

You do not need to call slapi_free_search_results_internal() after calling slapi_search_internal_callback_pb().
