      That means that the remote server doesn't like that key!

      What happens when you run the following command from the command line? 

      ssh -i /export/home/secbatch/.ssh/id_rsa -o PreferredAuthentications=p
+ublickey -v sftp.bloomberg.com

      Check your $PATH in order to ensure you run the same ssh binary as the script and also that you are logged as the same user.
