Usage

This provider can be the most useful in conjunction with Identity Server 4 to create the "Federation Gateway" to allow the users be authenticated against the local Active Directory via Active Directory Fedefation Services. ADFS 3.0 has limited implementation of OAuth2 protocol. With the Identity Server we can create the token provider service with support of OpenId Connect 1.0 protocol.

  {
    options.AdfsUrl = "https://fs.example.com";
    options.AdfsAudience = "idsrv-aud";
    options.ClientId = "idsrv";
