[Openswan Users] Yet Another EC2 Config Debug

It seems as though things are getting close, but I'm stumped by this
apparent disconnect between the .conf and .secrets files.

First, the error messages when I try to start up the connection:

Sep  8 19:51:18 pluto[3535]: "ec2check" #1: Can't authenticate: no preshared
key found for `<EC2 ELASTIC IP>' and `<CLIENT GATEWAY>'.
Sep  8 19:51:18 pluto[3535]: "ec2check" #1: no acceptable Oakley Transform
Sep  8 19:51:18 pluto[3535]: "ec2check" #1: sending notification

The necessary lines in the .conf:

        left=<EC2 LOCAL IP>
        leftid=<EC2 ELASTIC IP>
        right=<CLIENT GATEWAY>
        rightsubnet=<CLIENT ED>/24

And the line in the .secrets:

Anything wrong with these setups?
