[keycloak-user] Keycloak with Okta as SAML IdP - Logout

Hi, My configuration is as follows: the web application is a confidential client connected to Keycloak. Okta is configured as SAML IdP. Everything works fine, but not for the logout part. Okta requires you NOT to use the backchannel logout. This way the logout from Okta is done, but the session and access tokens on Keycloak are not invalidated. Is it possible to have a Single Logout with this configuration? Lorenzo
