These identity-specific details serve as a connective pathway, enabling the host collaborator to apply its trust policy to convert incoming affirmations into a web application compatible format. Subsequently, these assertions assist the application in making authorization determinations.

public void ConfigureServices(IServiceCollection services)

{

    services.AddAuthentication(sharedOptions =>

    {

        sharedOptions.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;

        sharedOptions.DefaultChallengeScheme = OpenIdConnectDefaults.AuthenticationScheme;

    })

    .AddAzureAd(options => Configuration.Bind("AzureAd", options))

    .AddCookie();

    services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

}

The aforementioned code selection introduces the PDUS authentication for an ASP.NET Core-based program.

The foundation of the PDUS structure was laid on a sturdy security architecture that draws on established protocols like WS-Federation, WS-Trust, SAML and integrates contemporary ones such as OAuth 2.0 and OpenID Connect.
