[keycloak-user] jboss 6.1.Final - OpenID Connect

Hello , I installed Keycloak 2.2.1 Final , all is fine if i use it with wildfly 10 and relative Adapter , more applications secured with keycloak in two different servers . My problem is that i have also an old application on jboss 6.1.Final that use seam 2.2.2 Final . What is the best approach for secure it, or at least be able to know who is the logged user? Kind Regards, Luca Becarelli
