OpenID Connect 1.0 Provider

We have decided to implement OAuth 2.0 and OpenID Connect 1.0 as a beta feature. While it's relatively stable there may inevitably be the occasional breaking change as we carefully implement each aspect of the relevant specifications. It's suggested to use a bit more caution with this feature than most features, we do however greatly appreciate your feedback. OpenID Connect 1.0 and it's related endpoints are not enabled by default unless you explicitly configure the OpenID Connect 1.0 Provider Configuration and OpenID Connect 1.0 Registered Clients sections.

As OpenID Connect 1.0 is fairly complex (the OpenID Connect 1.0 Provider role especially so) it's intentional that it is both a beta and that the implemented features are part of a thoughtful roadmap. Items that are not immediately obvious as required (i.e. bug fixes or spec features), will likely be discussed in team meetings or on GitHub issues before being added to the list. We want to implement this feature in a very thoughtful way in order to avoid security issues.

OpenID Certified™

General Availability

{{< roadmap-status >}}

This stage will signify official stability guarantees surrounding this implemented feature.

Miscellaneous

This stage lists features which individually do not fit into a specific stage and may or may not be implemented.

Multi-Issuer Configuration

{{< callout context="danger" title="Important Notes" icon="outline/alert-octagon" >}} This will be a planned breaking-change as per our Versioning Policy. {{< /callout >}}

The initial design of our OpenID Connect 1.0 implementation was before Multi-Domain Protection was considered. It's important for the future of Authelia that we carefully consider the implications of this and force users to configure a issuer per domain they wish to serve OpenID Connect 1.0 from and each of these are completely separate logical units.
