A Redmine plugin to make admin users become super user before they can actually employ admin powers.
This adds a ‘Become superuser’ link to the accout menu, if current user is an admin. The user must click this link and enter his password on the page shown next to actually become superuser. When superuser permissions are no longer required, the user may click ‘Giveup superuser’ link.
Superuser sessions expire automatically in 15 minutes (configurable.)
