The chrome-service noVNC exposes Viktor's live logged-in browser sessions (Instagram etc. — he'll sign in there for homelab browser to reuse). It was auth="required" = any authenticated user, and "Home Server Admins" includes emo (emil.barzin@gmail.com), so the admin group is not a sufficient gate. Add a host-specific case to the domain-wide forward-auth restriction allowing only Viktor's accounts (vbarzin@gmail.com + akadmin break-glass); everyone else, incl. emo, is denied at the noVNC. emo's AGENT already can't reach the browser (read-only RBAC blocks port-forward); this closes the human noVNC path.

# Catch-all forward-auth restriction: gate the admin-only hostnames to the
|
|
# "Home Server Admins" group. Bound to the "Domain wide catch all" application
|
|
# (binding stays UI-managed; only the expression is adopted here).
|
|
#
|
|
# Adopted into Terraform 2026-06-04 to add a carve-out: the Kubernetes Dashboard
|
|
# (k8s.viktorbarzin.me) ALSO admits the kubernetes-* RBAC groups, so
|
|
# namespace-owners (e.g. gheorghe) can reach the dashboard login page. The
|
|
# dashboard itself enforces per-namespace access via the pasted ServiceAccount
|
|
# token (stacks/rbac/modules/rbac/dashboard-sa.tf) — this policy only controls
|
|
# who reaches the page. All other admin-only hosts remain Home-Server-Admins-only.
