Logout with OIDC not working

[BramMeerten]

Describe the bug I configured OIDC following the datahub guide and I disabled JAAS. I used keycloak as an identity provider. Login works fine. When I try to logout I'm redirected to https://<my-datahub>/login*, but I'm nog logged out with my identity provider. So when I go back to datahub I'm automatically logged in again and can't switch accounts.

*This is also weird because I get a username/password form (+ sso button), but I have disabled JAAS and can't login with username/password.

To Reproduce Steps to reproduce the behavior:

1. Configure OIDC
2. Click on logout
3. Go back to datahub homepage
4. You are no longer logged in

Expected behavior I'm also logged out with my identity provider so I can switch accounts.

Additional context I suspect this pull request (play framework upgrade) has introduced the problem: https://github.com/datahub-project/datahub/pull/6626/files#diff-7cbee1cea8c44e4aa618564185bfcffbb23b1dd42e83c2c8bb3f381cc9b77cf5

The CentralLogoutController calls the setCentralLogout(true) method of its parent (LogoutController). This should make sure your also logged out with your identity provider. But on line 39 the logout method of LogoutController is no longer called. It seems it just clears the session and redirects to /login

public class CentralLogoutController extends LogoutController {
    // ...
    @Inject
    public CentralLogoutController(Config config) {
        _isOidcEnabled = config.hasPath("auth.oidc.enabled") && config.getBoolean("auth.oidc.enabled");
        setDefaultUrl(DEFAULT_BASE_URL_PATH);
        setLogoutUrlPattern(DEFAULT_BASE_URL_PATH + ".*");
        setLocalLogout(true);
        setCentralLogout(true);
    }

    // ...

-  public Result executeLogout() throws ExecutionException, InterruptedException {
+  public Result executeLogout(Http.Request request) {
        if (_isOidcEnabled) {
            try {
-              return logout().toCompletableFuture().get().withNewSession();
+              return Results.redirect(DEFAULT_BASE_URL_PATH)
+                    .removingFromSession(request);
// ...

There is at least one other user experiencing this issue according to the slack thread:

I have same issue. The session does not end with logout. It is still logged in.

This is still an issue, and also confirmed by other people in the the slack thread.

Tested on 0.10.4

[BramMeerten]

The pull request did not fix the issue for me, has anyone tried it?

By debugging I can see that it's in the right direction: The central logout logic is triggered (in DefaultLogoutLogic::perform) but it doesn't do anything if no UserProfile is found in the session or request.

For some reason the UserProfile can't be found in the request/session. We can see that it gets set, but in the following requests it's no longer set.

Maybe the this issue is related, but I enabled the PlayCacheSessionStore and it still didn't work.

@FirKys this PR worked for you? Do you have some special settings regarding sessions/cookies/...?

Still experiencing this issue - can we please re-open this? Thanks.

@LucaDorinAnton - Can you confirm that the logout url is configured in your oidc provider? It should point to the login page <hostname>/login? If the logout url is set to any other location, the oidc login flow will be triggered and log you back in.

[LucaDorinAnton]

@david-leifker Just to confirm, do you mean backchannel_logout_uri ?

https://openid.net/specs/openid-connect-backchannel-1_0.html#BCRegistration

[david-leifker]

From okta, the configuration is post_logout_redirect_uri. The underlying logout when oidc is enabled is using the pac4j library which is following configuration from the idp. I believe post_logout_redirect_uri is also the name of the query parameter in the flow and is part of the docs here: https://openid.net/specs/openid-connect-rpinitiated-1_0.html#RPLogout

@LucaDorinAnton

[BramMeerten]

@david-leifker , Shouldn't the post_logout_direct_uri be set by datahub (Relying Party) and not the Oidc Provider? Because the Relying Party should indicate where it wants to be redirected after the logout. In my Oidc Provider (Keycloak), I have configured the client to allow any redirect url.

It's been a while since I tried to debug this issue, so I don't remember very well. But I think datahub only clears the session, and doesn't call the logout endpoint of the Oidc Provider at all (See my original post and this comment).

[LucaDorinAnton]

Similarly to @BramMeerten, we're also using KeyCloak and we allow any redirect URI. I tried inspecting the network traffic and I haven't seen DataHub attempting to use the post_logout_direct_uri parameter.

[georgeleeru]

I'm having this same issue in v0.13.3. I'm taken back to the landing page after I click the /logOut url. I can however logout in two steps - by accessing the "end_session_endpoint" url in my .well-known configuration and then the datahub /logOut url.
