Hello,
I am trying to set up SPNEGO authentication through Keycloak. I have installed Keycloak on a windows server, configured a client as shown below and set up the realm in jboss. But I consistently receive the error message GSSException: Defective token detected (Mechanism level: GSSHeader did not find the right tag). I am using IE 11, and the url for the web app is https://gig-jboss-dev.ajga.com:8443/CBN
