Our Jenkins basically parses the commit e-mail, i.e. [username@domain] and only uses [username] for the jenkins user. But our e-mails are [firstname.lastname@domain]. The problem is Jenkins doesn’t allow creating users with dots, so our users have underscores. So the builds are not mapped to the user in Jenkins. But you can see a build history then for users with the pattern [firstname.lastname], which actually don’t exist. How could this be resolved to map them to our underscore pattern [firstname_lastname] since Jenkins doesn’t allow dots for the username?
