Changelog Entry

Description

Add a new OAUTH_LOGOUT_URI environment variable that allows specifying a full custom logout URI for OAuth providers that do not support the standard OIDC end_session_endpoint discovery (e.g. AWS Cognito).

Closes #19182

Added

OAUTH_LOGOUT_URI PersistentConfig in config.py — accepts a full custom logout URL via environment variable
Early return in the /signout handler: when OAUTH_LOGOUT_URI is set and an OAuth session exists, redirect to it directly instead of attempting OIDC discovery

Changed

Startup warning now also checks OAUTH_LOGOUT_URI — the "logout will not work" warning is suppressed when either OPENID_PROVIDER_URL or OAUTH_LOGOUT_URI is configured

Fixed

OAuth logout for providers like AWS Cognito that use a custom logout endpoint with different parameters (e.g. client_id + logout_uri) instead of the standard OIDC end_session_endpoint with id_token_hint

Additional Information

AWS Cognito requires a logout URL like https://<domain>/logout?client_id=<id>&logout_uri=<uri> — this cannot be discovered via OIDC metadata
The new variable is fully opt-in: when unset (default ""), the existing OIDC discovery flow is used unchanged
