If you combine OIDC with local accounts or if your OIDC provider is an
external company (Facebook, GitHub, …) it makes sense for HedgeDoc to
show a additional login modal so users know that they will leave the
page.
However, if OAuth2/OIDC is a deployment's primary sign-in method and a
local OIDC provider is being used, users expect the common SSO method
being used, and he "Choose method" modal is a redundant extra click.
Essentially, you may have to click login thrice:
- Click login -> modal opens
- Click Login with provider -> provider login opens
- Log in (unless you are logged in already)
This simple patch adds an auto-login configuration, which makes the Sign
In button link straight to the provider's OAuth2 flow, improving the UX
of tHedgeDoc's login.
