Hi,

The main point of Keycloak is to provide SSO for browser based apps. BASIC authentication is currently supported just for REST endpoints, so no authentication popup. And it's generally not recommended. So if you have opportunity to redesign and avoid BASIC authentication and authentication popup, that would be the preferred way IMO.

Otherwise if you really need BASIC authentication with the popup, then it will be better to avoid use Keycloak adapter at all in your WAR. Instead you can likely use Tomcat JAAS realm and configure the Keycloak JAAS login module (probably DirectAccessGrantsLoginModule) - https://keycloak.gitbooks.io/securing-client-applications-guide/content/topics/oidc/java/jaas.html

Not sure why you want authentication popup?

Hi there,

I have a war application deployed to tomcat that is currently secured with BASIC authentication through tomcat's realm. When I try to access secured page, the authentication popup appears.

I would like to switch to keycloak securitu but I'm not sure if it is possible to configure keycloak to force this authentication popup.

I tried setting it up but when I try to access the secured page, instead of authentication popup I am redirected to keycloak page "Client is not allowed to initiate browser login with given response_type. Standard flow is disabled for the client."

I've followed the instructions from https://github.com/keycloak/keycloak/tree/master/examples/basic-auth and http://keycloak.github.io/docs/userguide/keycloak-server/html/ch08.html#tomcat-adapter.

Is it possible to setup tomcat and keycloak so that the authentication popup would be forced to appear?

Thanks
