We are attempting to write a plugin that performs an action when a user attempts to login that will complete before the authentication finishes. On Jira there is a 'BeforeUserAuthenticate' event which suits this need but there doesn't seem to be an equivalent event for Confluence. This means we have to instead use the LoginEvents which only occur after authentication succeeds or fails. Is there anything Confluence has that works in the same way as Jira and if not could a BeforeUserAuthenticate event be added?
