title: Why is it not possible to set options in IdentityServer?
body: <p>I have been tried to apply several kind of setting on Startup.cs as shown ob the given link:</p>
  <p><a href="https://identityserver4.readthedocs.io/en/latest/quickstarts/2_interactive_aspnetcore.html" rel="nofollow noreferrer">https://identityserver4.readthedocs.io/en/latest/quickstarts/2_interactive_aspnetcore.html</a></p>
  <p>But unfortunately I cannot set the base url for Authority parameter when I check on the following url:</p>
  <p>https://my-pc-id:8085/_configuration/MyApp.WebUI</p>
  <p>It seems to be weird, because if we cannot set this parameter, why there is such an option on this config?</p>
  <pre><code>using System.IdentityModel.Tokens.Jwt;
  
  // ...
  
  JwtSecurityTokenHandler.DefaultMapInboundClaims = false;
  
  services.AddAuthentication(options =&gt;
      {
          options.DefaultScheme = &quot;Cookies&quot;;
          options.DefaultChallengeScheme = &quot;oidc&quot;;
      })
      .AddCookie(&quot;Cookies&quot;)
      .AddOpenIdConnect(&quot;oidc&quot;, options =&gt;
      {
          options.Authority = &quot;my-pc-id:8085&quot;;
  
          options.ClientId = &quot;mvc&quot;;
          options.ClientSecret = &quot;secret&quot;;
          options.ResponseType = &quot;code&quot;;
  
          options.SaveTokens = true;
      });
  </code></pre>
