Several dead ends (TOTP/WebAuthn setup after an anonymous visit bounces
through login and lands on "/") trace back to Brand.default_application
being unset, which falls back to /if/user/ - blocked for type=external
Matrix accounts. Set it to the matrix Application. Only changes the bare
"/" fallback; explicit URLs like /if/admin/ are unaffected.
2FA is intentionally optional (not_configured_action=skip on the login
flow's validate stage). Users who opt in use the built-in single-stage
default-authenticator-totp-setup / -webauthn-setup flows directly, since
/if/user/ is blocked for type=external Matrix accounts. Both flows had
nothing after the setup stage, so completing enrollment fell back to
that same blocked dashboard. Appended the shared redirect stage.
matrix-recovery existed but had zero stage bindings, and the real login
flow (default-authentication-flow, MAS's authentication_flow) never
linked to it, so users had no working "forgot password" path. Reused
the same default-recovery-* stages the built-in default-recovery-flow
already uses successfully, added our redirect stage at the end, and
set default-authentication-identification.recovery_flow accordingly.
After the login stage, the flow had no destination, so it fell back to
authentik's own /if/user/ interface - which refuses type=external users
(the correct type for Matrix-only accounts), showing "Die Oberflaeche
kann nur von internen Nutzern geoeffnet werden". Added a static redirect
to https://axion1337.chat as the final stage.
The prompt stage had 16 unrelated system policies bound (OOBE, user
settings, recovery, etc.), likely from a "select all" slip while
configuring it manually. They crash when evaluated in an anonymous
enrollment context (AnonymousUser has no group_attributes, etc.),
surfacing as opaque errors after form submit. Cleared live and via
the blueprint so re-application doesn't reintroduce them.
The matrix-invitation flow only had Invite+Prompt stage bindings, both
at order=0 (undefined order), missing the Write/Password/Login stages
entirely — invited users were never written to the DB. Applied the fix
live in-cluster (mirroring the working matrix-enrollment stage chain),
and captured it as an Authentik Blueprint (ConfigMap, mounted via
blueprints.configMaps) so the flow state is reproducible via GitOps
instead of manual admin-UI clicks.
