How to integrate Keycloak SSO and SLO with AKHQ using OIDC?

[hooriehghahremani]

I am trying to integrate Keycloak with AKHQ, using the OIDC (OpenID Connect) protocol for Single Sign-On (SSO) and Single Logout (SLO). I have successfully implemented SSO with the identity provider, but I am facing an issue with SLO.

My expectation is that when I log out from Keycloak, I should be logged out from all clients, and vice versa,but this is not happened and i can not understand why.

Here are the configuration setting for these services:

Akhq config:

        micronaut:
          security:
            enabled: true
            endpoints:
             logout:
              enabled: true
              path: http://keycloak/realms/myrealm/protocol/openid-connect/logout
              get-allowed: true
            redirect:
             logout: http://keycloak/realms/myrealm/protocol/openid-connect/logout
             login-success: "/ui"
            oauth2:
              enabled: true
              logout-uri: http://keycloak/realms/myrealm/protocol/openid-connect/logout
              redirect-uri: http://keycloak/realms/myrealm/protocol/openid-connect/logout
              callback-uri: "http://akhq/oauth/callback/keycloak"
              clients:
                keycloak:
                  client-id: "akhq"
                  client-secret: "*****"
                  openid:
                    issuer: "http://keycloak/realms/myrealm"
                    end-session:
                      enabled: true
                      url: http://keycloak/realms/myrealm/protocol/openid-connect/logout

Keycloak setting:

Client ID: http://akhq
