Here is an example of how the Bulk Loader properties should be provided:
actionToTaskMapping=create.Create User;modify.Modify User;delete.Delete User
password=<Insert current password here>
Make sure you replace <hostname> with the appropriate value the virtual machine has assigned. The password field should already have a password include. If this value is empty or seems incorrect, an option would be to put the file in plaintext and upon first run the password will be encrypted.
