title: Identity Server 4 and auto redirect on sign out
body: <p>Playing around with a demo project from PluralSight, I am trying to have the IDP redirect back to the server app on sign out.</p>
  <p>The <strong>PostLogOutRedirectUris</strong> is defined in the config for the Client at the IDP level, but it doesn't seem to have any effect.</p>
  <pre><code>public static IEnumerable&lt;Client&gt; Clients =&gt;
      new Client[]
      { 
          new Client
          {
              ClientId = &quot;bethanyspieshophr&quot;,
              ClientName = &quot;Bethany's Pie Shop HRM&quot;,
              AllowOfflineAccess = true,
              AccessTokenLifetime = 120,
              RequireConsent = false,
              RequirePkce = true,
              AllowedGrantTypes = GrantTypes.Code,
              ClientSecrets = { 
                  new Secret(&quot;108B7B4F-BEFC-4DD2-82E1-7F025F0F75D0&quot;.Sha256()) },
              RedirectUris = { &quot;https://localhost:44301/signin-oidc&quot; },
              PostLogoutRedirectUris = { &quot;https://localhost:44301/signout-oidc&quot; },
              AllowedScopes = { &quot;openid&quot;, &quot;profile&quot;, &quot;email&quot;, &quot;bethanyspieshophrapi&quot; }
          }             
      };
  </code></pre>
  <p>If I manually at runtime set the LoggedOutViewModel it works as expected.</p>
