<div>Marek, I tried to manually call keycloak login url with prompt=none but it didn't redirect back to my redirect_uri, instead it stayed at the login page.</div>
<div>Below is an example of the login url i'm calling.</div>
<div><br>
</div>
<div>http://keycloak-domain.com.br/auth/realms/accounts/protocol/openid-connect/auth?redirect_uri=http://my-application.com.br/app-web/&response_mode=fragment&response_type=code&client_id=app-web&<b>prompt=none</b></div>
<div><br>
</div>
<div>I need an URL to call to know if the user is logged in or not without being redirected to the login page.</div>
<div>I need this because KeycloakSecurityContext is not available at not restricted URLs.</div>

<div class="moz-cite-prefix">I think your possibilities are either:<br>
- Use different client for keycloak.js (public client) and different client for your confidential servlet application<br>
- Don't use keycloak.js at all, but instead do some HTTP Filter to deal with "autologin" . You will manually try to redirect to keycloak with "prompt=none" . If user is not logged, keycloak will redirect back to the callback redirect_uri, where you recognize
if there is "code" or "error" parameter and based on that, you know if user is logged or not. If user is logged, you can redirect to secured URL to properly trigger authentication process (maybe you can optimize this step by reuse the "code", which you already
have and directly open the secured URI with it, but I am not 100% sure if it works with considering that you also need correct "state" etc.) Otherwise, you can set some state or something, to recognize that autologin has been already unsuccessfully tried.<br>
<br>
Maybe you can create JIRA to request support "autologin" for other types of clients then public keycloak.js clients.<br>

<p>Hi,</p>
<p> I wonder if it's possible to just check the SSO state with a confidential client. My use case is the following one:</p>
<p>- I have a website which uses a confidential client to login with Keycloak.</p>
<p>- I want to add autologin to this website.</p>
<p>- So I use the javascript adapter with the following option object for the init method: { onLoad: 'check-sso' }. The javascript adapter is built without the secret key in its constructor (obviously if I put the secret key in there, there's no point to use
a confidential client at all).<br>
</p>
<p>But Keycloak fails with a "type=CODE_TO_TOKEN_ERROR, error=invalid_client_credentials" error.<br>
</p>
<p>So I don't know how feasible or secure is to just check that the Keycloak session inside the cookie of the user's browser is still valid. In my case, the browser doesn't need to get the user info, access token, etc, because what I'll do is redirect the user
to the Keycloak login page with the confidential client afterwards is the operation is successful. Since the Keycloak session is valid, Keycloak should redirect back with the authentication code without asking credentials to the user.<br>
</p>
<p>Additional note: the CORS header isn't added to 400 responses in Keycloak, so it was a bit confusing looking at the JS console in the browser, because it complained about CORS but it was just Keycloak giving the 400 response without the allow-origin header.<br>
</p>
Thanks.<br>
