It takes a null terminated array of LDAPControl structures usually obtained by a call to the ldap_parse_result function. A returncode which points to the sort control result code,and an array of LDAPControl structures that list the client controls to use with the search. The function also takes an out parameter attribute and if the sort operation fails, the server may return a string that indicates the first attribute in the sortKey list that caused the failure. If this parameter is NULL, no string is returned. If a string is returned, the memory should be freed by calling the ldap_memfree function.
