# Login

`GET /auth/login`

Initiate SSO login. Redirects to IdP.

## Query parameters

- `provider` 'oidc' | 'saml' — SSO providers accepted by ``GET /auth/login``. Typing the ``provider`` query param with this enum lets FastAPI reject unknown values with a ``422`` at the validation layer instead of the handler falling through to a generic error for an input it was never going to support.

## Response `200`

Successful Response

- unknown

## Other responses

- `400` — Authentication provider not enabled
- `404` — SSO authentication is not configured on this server
- `422` — Validation Error
