M Hickford	191a74d622	Record OAuth client type at registration (#21316) ... The OAuth spec [defines two types of client](https://datatracker.ietf.org/doc/html/rfc6749#section-2.1), confidential and public. Previously Gitea assumed all clients to be confidential. > OAuth defines two client types, based on their ability to authenticate securely with the authorization server (i.e., ability to > maintain the confidentiality of their client credentials): > > confidential > Clients capable of maintaining the confidentiality of their credentials (e.g., client implemented on a secure server with > restricted access to the client credentials), or capable of secure client authentication using other means. > > **public > Clients incapable of maintaining the confidentiality of their credentials (e.g., clients executing on the device used by the resource owner, such as an installed native application or a web browser-based application), and incapable of secure client authentication via any other means.** > > The client type designation is based on the authorization server's definition of secure authentication and its acceptable exposure levels of client credentials. The authorization server SHOULD NOT make assumptions about the client type. https://datatracker.ietf.org/doc/html/rfc8252#section-8.4 > Authorization servers MUST record the client type in the client registration details in order to identify and process requests accordingly. Require PKCE for public clients: https://datatracker.ietf.org/doc/html/rfc8252#section-8.1 > Authorization servers SHOULD reject authorization requests from native apps that don't use PKCE by returning an error message Fixes #21299 Co-authored-by: wxiaoguang <wxiaoguang@gmail.com> Co-authored-by: Lunny Xiao <xiaolunwen@gmail.com>	2 years ago

Johnny Oskarsson	a07e67d9cc	Minimal OpenID Connect implementation (#14139) ... This is "minimal" in the sense that only the Authorization Code Flow from OpenID Connect Core is implemented. No discovery, no configuration endpoint, and no user scope management. OpenID Connect is an extension to the (already implemented) OAuth 2.0 protocol, and essentially an `id_token` JWT is added to the access token endpoint response when using the Authorization Code Flow. I also added support for the "nonce" field since it is required to be used in the id_token if the client decides to include it in its initial request. In order to enable this extension an OAuth 2.0 scope containing "openid" is needed. Other OAuth 2.0 requests should not be impacted by this change. This minimal implementation is enough to enable single sign-on (SSO) for other sites, e.g. by using something like `mod_auth_openidc` to only allow access to a CI server if a user has logged into Gitea.
