JBoss.orgCommunity Documentation
To enable the propagation of identity across the Chat webapp, you are required to enable the SSO valve on the Tomcat-based Application server.
For the Jboss server, edit jboss/server/default/deploy/jboss-web.deployer/server.xml.
For the Tomcat server, edit tomcat/conf/server.xml.
The valve should already be there, you just need to uncomment it if it is not already done.
<Valve className="org.apache.catalina.authenticator.SingleSignOn"/>
In case of the cluster deployment, you may want to use ClusteredSingleSignOn instead.
<Valve className="org.jboss.web.tomcat.service.sso.ClusteredSingleSignOn"/>
