This is a simple example event listener SDK Plugin for the Curity Identity Server.
It demonstrates how to plug in to the event listener framework (introduced in version 2.2) by registering two event listeners; one for successful and one for failed client authentication attempts. On a failed authentication the plugin uses a Bucket (introduced in version 2.4) to create a counter for the client, and will increment the counter on each authentication failure. The event listener handling successful authentication resets the same counter, so that only consecutive failed attempts are counted. After three consecutive failed attempts, the plugin logs a message on INFO level. At 10 consecutive failed attempts, the plugin logs a message on WARN level.
