  • Patent number: 8015195
    Abstract: The present invention provides a system and a computer-implemented method for modifying an entry name in a directory database. The method comprises the steps of: modifying, in response to a request for modifying operation of entry names, entry mapping information in accordance with the modification that is requested for modifying operation of entry names, wherein each piece of entry mapping information is used for indicating the correspondence relation between pre-modification entry name information and post-modification entry name information; asynchronously performing modifying operation of a corresponding entry name in accordance with respective pieces of entry mapping information when a predetermined condition for updating the directory database is met.
