From df55f9b189174767296e562389948e5250f1df73 Mon Sep 17 00:00:00 2001 From: Noah Snelson Date: Thu, 20 Jul 2023 01:02:45 -0700 Subject: [PATCH] Add a link to OpenID Issuer URL in WebFinger response (#26000) This change adds an entry to the `links` field of the `/.well-known/webfinger` response. The new entry points to the `appURL` as an OpenID issuer. This is consistent with the output of `/.well-known/openid-configuration`, which also uses the value of `appURL`. This change is required for Tailscale SSO to work, as it uses the OpenID Issuer URL when querying the Tailscale user email during signup/login ([docs](https://tailscale.com/kb/1240/sso-custom-oidc/#webfinger-setup)). --- routers/web/webfinger.go | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/routers/web/webfinger.go b/routers/web/webfinger.go index 0966b04951..faa35b8d2f 100644 --- a/routers/web/webfinger.go +++ b/routers/web/webfinger.go @@ -106,6 +106,10 @@ func WebfingerQuery(ctx *context.Context) { Type: "application/activity+json", Href: appURL.String() + "api/v1/activitypub/user-id/" + fmt.Sprint(u.ID), }, + { + Rel: "http://openid.net/specs/connect/1.0/issuer", + Href: appURL.String(), + }, } ctx.Resp.Header().Add("Access-Control-Allow-Origin", "*")
