Ensure 'establishTrustInClient' is set to 'required' within the CSIv2 Authentication Layer
Descripción
The CSIv2 Authentication policy configures security at the Authentication layer when accessing EJB applications using RMI/IIOP. Audit: reads server.xml, configDropins/defaults/*.xml, configDropins/overrides/*.xml and files pulled in with <include> for every Liberty server found under WLP_USER_DIR, /opt/ibm/wlp/usr, /opt/IBM/WebSphere/Liberty/usr, /opt/ol/wlp/usr, /usr/local/wlp/usr or /config; it ignores XML comments and fails if no server.xml is readable. establishTrustInClient on the CSIv2 <authenticationLayer> must be Required. Passes when no <authenticationLayer> element is configured (feature not in use). An unset attribute is accepted because the Liberty default is compliant.
