title: Sign out clients only in IdentityServer4
body: <p>Is there a way to execute a single-sign-out <strong>for clients only</strong> using IdentityServer4? I have no problem executing single-sign-out for clients and IdentityServer using the <code>endsession</code> endpoint. What I would like to do, however, is provide a way to force all clients to re-authenticate upon next request (to get fresh claims) but not force the user to re-enter credentials.</p>
  
  <p>The use case is for the user to edit profile information which is stored in claims. For example, their name. When the user submits a change to this information, all other clients need to be made aware that the claims they currently have are no longer valid. This can be achieved by signing the user out completely, but then the user must re-enter their id and password.</p>
  
  <p>Looking at the flow, I guess what I'm trying to do is execute the internal <code>EndSessionCallbackEndpoint</code> directly, without removing the authentication cookie for IdentityServer itself.</p>
