Could someone help explain the new feature to allow auth providers to provide a custom URL? I tried to read through the code but didn’t really understand what was happening. Any insight would be great — thanks!

I believe it’s used in the SAML auth provider if that’s any help to you:

Should we clarify in the settings copy if this is for saml only @eviltrout?

It’s not a site setting though, that’s an internal field that plugin authors can use to set a custom URL.

As to how to use it, any plugin that creates an `omniauth.provider` can supply a `:custom_url` if they like like in the SAML example above.
