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

 

JBoss web app configuration in standalone.xml ======================================================

 

<subsystem xmlns="urn:jboss:domain:keycloak:1.1">

            <secure-deployment name="cbn-war-17.0.0.16-SNAPSHOT.war">

                <realm>master</realm>

                <resource>CBN</resource>

                <public-client>true</public-client>

                <realm-public-key>(key from keycloak)</realm-public-key>

                <auth-server-url>http://gig-msnet-dev.ajga.com:8080/auth</auth-server-url>

                <ssl-required>EXTERNAL</ssl-required>

            </secure-deployment>

        </subsystem>
