[keycloak-user] chrome on windows

Hi, Somehow, when using keycloak SAML auth on our application, chrome on windows is presenting us a basic http popup logon window. In that case, the URL looks like: We have to cancel that popup, to end up in the regular keycloak login page. The URL then becomes: Since this only happens on chrome on windows, I thought that this perhaps was a kerberos-auth going wrong. So i disabled kerberos, but it keeps happening. Using other browsers, we end up in the regular second /login-actions/ logon screen straight away. The chrome popup is also NOT useable: if we provide a valid username/password, we will NOT become authenticated, but we end up in the "WE'RE SORRY... Unexpected error when handling authentication request to identity provider." Can anyone explain this? (keycloak 2.3.0) MJ
