In a try to do some automatic cleanup of licenses, I'm investigating the api's on JIRA, Bitbucket and Confluence to find out when a user was last authenticated to an application.
I managed to pull the info from JIRA over the crowd api, and from bitbucket over it's rest api, but on confluence I can't seem to find this information exposed anywhere.
The confluence user information doesn't provide it, and JIRA crowd doesn't tell me when someone authenticated through the integration.
