Loop continues Now explicitly throws HttpForbiddenException with descriptive message when SSO headers are present but user doesn't exist. The catch block also re-throws HttpForbiddenException to ensure it propagates properly and doesn't fall through. This prevents the loop without implementing auto-provisioning. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- apps/backend/src/services/auth/auth.middleware.ts | 12 ++++++++++-- 1 file changed, 10 insertions(+), 2 deletions(-) diff --git a/apps/backend/src/services/auth/auth.middleware.ts b/apps/backend/src/services/auth/auth.middleware.ts index 9e26c0198..ad1843b91 100644 --- a/apps/backend/src/services/auth/auth.middleware.ts +++ b/apps/backend/src/services/auth/auth.middleware.ts @@ -156,15 +156,23 @@ export class AuthMiddleware implements NestMiddleware { return next(); } else { + // User authenticated by Authelia but doesn't exist in Postiz + // Return error instead of falling through to prevent redirect loop if (process.env.NODE_ENV !== 'production') { - console.log('[SSO] User not found or not activated, continuing to normal auth'); + console.error('[SSO] User authenticated by Authelia but not found in Postiz:', lookupEmail); } + throw new HttpForbiddenException('Your SSO account is not authorized for Postiz.

Removed the custom error message parameter from the throw statement. The exception will still properly break the redirect loop by: 1. Returning 401 status 2. Clearing auth cookies via exception filter 3.
