  That wasn't the problem.  "Invalid request authenticator" means that the shared secret is wrong.  If you had set "request_message_authenticator = yes", then the message would have been "invalid message authenticator", or maybe "missing message authenticator"

  What I suspect happened is that you were editing clients.conf, and then *not* restarting the server.  After changing "require_message_authenticator = no" and restarting the server, it picked up the new secret.
