***************************************************************************
    Description: The backup.c sample demonstrates how to backup and restore
    attribute anmes and values for anobject.  The backup/restore APIs are 
    object based. It is the developer's responsibility to decide how to
    deicide how to store the information so it can be restored when calling
    ldap_restore_object. If any of one the attributes in the user object has 
    been encrypted  user needs to supply a password for encryption, same
    password  should be supplied for decryption. If non of the attributes are 
    encrypted an empty string ie "" needs to passed as part of the 3rd
    parameter in both the functions, backup and restore. 

    eDirectory 8.8 or newer is required.
