I'm trying to use the User Authentication API module. My goal is to add some post-processing after successful Drupal 7 login that posts JSON to an external web service. This would be work very similar to the Webform Remote Post module, but for the login page.
My problem is that even though the module is installed fine, and things look good on the page which displays detected plugins, nothing seems to fire at login. What do I need to add to see this plugin framework interact with a user login event?
This screenshot shows I have all the pieces in place.
