Bùi Hà, a Canonical staff member based in Japan, has written an introduction to Juju’s account system and a tutorial on how to change passwords:
Juju has an internal user framework, which supports sharing of controllers and models. Using Juju user feature, a sysadmin could separated users for controllers as in multiple clouds deployment or for users as in multiple systems deployment. Each juju user can have its own permissions at application, model, or controller layer. This separation of responsibilities allow multiple users to manage multiple infrastructures with a clear border of responsibilities.
The post includes quite a few sections, including:
- recovering the admin password
- accessing Juju’s internal database directly
- changing passwords
