This is a fork of IdentityServer4 that is meant to keep existing software that depends on IdentityServer4 updated with the latest .NET framework version.

For a state of the art implementation, updates and innovations please use Duende IdentityServer.

Our goal is to keep any core changes to IdentityServer4 to a minimal so compatibility is maximized. Below you can find some of those changes in order to decide if they could affect your project:

• Api Resource Scopes can be used as Api Scopes: when validating a authorize request, IdentityServer4 validates scopes based on existing Api Resources and Api Scopes. We have updated this code to match requested scopes with Api Resource Scopes as well.

IdentityServer is a free, open source OpenID Connect and OAuth 2.0 framework for ASP.NET Core. Founded and maintained by Dominick Baier and Brock Allen, IdentityServer4 incorporates all the protocol implementations and extensibility points needed to integrate token-based authentication, single-sign-on and API access control in your applications. IdentityServer4 is officially certified by the OpenID Foundation and thus spec-compliant and interoperable. It is part of the .NET Foundation, and operates under their code of conduct. It is licensed under Apache 2 (an OSI approved license).
