Can you secure .Net WS with OTDS as Authentication Server

Still looking into how to do this, I am using .NET Core 3.1 REST web service and i want to secure it using OTDS as the authentication server, rather than create my own username and password system.
Has anybody else tried doing this?

@FredAlainIA

I have managed to resolve this myself using built in standard OAuth middleware that is avaiable for .net core. My example code below is for .net core 3.1 so please bear that in mind.

All i did was modify the startup.cs to turn on authentication and point to my OTDS server.
You need to setup Content Server OAuth Client as well in /otds-admin.
In the example below the name used is 'SOMENAME' ... this needs to be the name of what you have setup.
To set the password go to partitions and find the member of the oauth clients and reset the password to what ever you want.

Last, i am only bothered about the user being authenticated ... i am not bothered about who they are or what roles they may or may not have so the token info url may or may not work too but it looks right according to their api documentation.

public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}

    public IConfiguration Configuration { get; } 

    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddControllers();

        services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_3_0);

    //START - ADD SECURITY
        JwtSecurityTokenHandler.DefaultMapInboundClaims = false;

        services.AddAuthentication(options =>
        {
            options.DefaultScheme = "Cookies";
            options.DefaultChallengeScheme = "OTDS";
        })
            .AddCookie("Cookies")
            .AddOAuth("OTDS", options =>
            {
                options.AuthorizationEndpoint = "http://CONTENTSERVERADDRESS:8002/otdsws/login";
                options.TokenEndpoint = "http://CONTENTSERVERADDRESS:8002/otdsws/login";
                options.UserInformationEndpoint = "http://CONTENTSERVERADDRESS:8002/otdsws/v1/authentication/oauth/tokeninfo";

                options.ClientId = "SOMENAME";
                options.ClientSecret = "***********";

                options.CallbackPath = "/";

                options.Scope.Add("resource:Content+Server");

            });

 //END - ADD SECURITY

    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IWebHostEnvironment env, ILoggerFactory loggerFactory, ISerialiser jsonHelper)
    {
        loggerFactory.AddLog4Net();

        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }

        ILogger logger = loggerFactory.CreateLogger("UnhandledException");

        app.ConfigureExceptionHandler(logger, jsonHelper);

        app.UseRouting();

        //START - ADD SECURITY
        app.UseAuthentication();
        app.UseAuthorization();
        //END - ADD SECURITY

        app.UseEndpoints(endpoints =>
        {
            //endpoints.MapControllers();

            //START - ADD SECURITY
            endpoints.MapControllers().RequireAuthorization();
            //END - ADD SECURITY
        });

    }
