I thought about it, but at the moment I thought about what is the
point of having the confidential client if the public one is needed,
I discarded that option. Since the autologin affects the same
website, there's no point to have two clients attacking the same
resource. The public client is the weakest link of the chain, so
having a secret key doesn't add anything to security; only for
accountability, maybe.<br>

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>

Oh well, it's a website made in PHP, not a servlet, but the same
idea can be applied. But I had to discard that option too due to
technical reasons: I'm not exactly in control of the whole website,
since I'm adding the autologin to a project I didn't work on in the
past, which isn't as well engineered for extensibility as Keycloak
:).<br>

Maybe you can create JIRA to request support "autologin" for
other types of clients then public keycloak.js clients.<br>

Thanks, Marek. I'll think about it. It's very likely that I'll open
a JIRA issue to discuss this further.<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>
