From 50a36ff93a9d1c697c976a1db498bc5633f2cd7c Mon Sep 17 00:00:00 2001 From: Erich Blume Date: Sat, 6 Jun 2026 18:07:13 -0700 Subject: [PATCH] heph Authentik: grant offline_access scope (fixes spoke sync refresh-token 400) The heph CLI requests scope "openid offline_access", but the Authentik heph OAuth2 provider only mapped openid/email/profile. Without the offline_access mapping the issued refresh token is bound to the login session rather than the 30-day refresh-token window; once the session lapses, hephd's refresh_token grant returns 400 Bad Request and spoke sync silently degrades (heph sync --status -> auth_failure: true). Add the built-in offline_access scope mapping to the provider's property_mappings and document the requirement in the service reference.
