[keycloak-user] Disable Sticky Sessions?

Hi, I am using keycloak as a broker where the user in a browser can choose which identity provider to use for authentication and this works just fine. We have also set up a "headless flow" where an application using the kc_idp_hint can preselect a special identity provider which can authenticate the user (with a special authenticator) without user interaction. This used to work fine, but with Keycloak 3.2.x this breaks, since now Keycloak requires cookies to be enabled. As far as I can tell this is because the AUTH_SESSION_ID cookie used for "Sticky sessions" is now a hard requirement. Is there a way to disable this hard requirement on cookies? I know that enabling cookies will fix this for the application, but my problem is that there is multiple implementation of this application, and I don't control any of them. Best regards, Tomas
