Keycloak SSO — single sign-on, self-service, and federation for all workspace services
Sync users from Keycloak to workspace database, then provision their mailboxes
Mailboxes also auto-provision in the background every 5 minutes via the
hv-provisioner sidecar — click here only if you need it
immediately (e.g. a new user just signed in and you want them to land
directly in their inbox).
