Stefan Markmann cf5d34acf6 revert: "fix: skip provider button auth only redirect (#3309)" (#3314) ... This reverts commit 9c61c49ec2. The original fix broke nginx deployments using `auth_request`. When `/oauth2/auth` returns 302, nginx's `auth_request` module treats this as an internal error: [error] auth request unexpected status: 302 while sending to client nginx then returns **500 Internal Server Error** to the browser. > If the subrequest returns a 2xx response code, the access is allowed. If it returns 401 or 403, > the access is denied with the corresponding error code. Any other response code returned by the > subrequest is considered an error. https://nginx.org/en/docs/http/ngx_http_auth_request_module.html The nginx `auth_request` module has strict semantics (non-negotiable): | Subrequest status | nginx behavior | |---|---| | 2xx | Allow request | | 401 / 403 | Deny → trigger `error_page` | | **Any other status** | **Internal error → 500** | The `/oauth2/auth` endpoint is used as a **policy oracle** (yes/no decision), not as a browser-facing endpoint. It cannot return redirects. Any nginx deployment with: - `skip-provider-button=true` - Using `auth_request` directive Will receive 500 errors instead of the expected authentication flow. The correct fix for #334 is a **documentation update**, not a code change: ```nginx error_page 401 = @oauth2_signin; location @oauth2_signin { return 302 /oauth2/sign_in?rd=$scheme://$host$request_uri; } ``` This keeps `/oauth2/auth` as a pure 401/2xx oracle and lets nginx perform the proper 302 redirect to the browser. - Original Issue: #334 - Regression introduced in PR: #3309 Signed-off-by: Stefan Markmann <stefan@markmann.net> Signed-off-by: Jan Larwig <jan@larwig.com> Co-authored-by: Jan Larwig <jan@larwig.com>		2026-01-18 00:36:08 +01:00
