Enabling Propagation of Security Credentials for an EJB 3.1 lite Bean in EAP 6 from a Servlet

Issue

• Require to propagate Security Credential from a Servlet to the corresponding called EJB 3.1 lite.
• The jboss-web.xml file is configured as follows:

<?xml version="1.0" encoding="UTF-8"?>
<jboss-web>
    <context-root>/some_context</context-root>
    <servlet>
        <servlet-name>The_SERVLET_NAME</servlet-name>
        <run-as-principal>SOME_PRINCIPAL</run-as-principal>
    </servlet>
    <security-domain>java:/jaas/<SOME_DOMAIN></security-domain>      
</jboss-web>

• Within the Servlet, when the EJB Method is invoked, it does not return the caller principal as the one that is called from or as it is expected.
• All methods in the EJB should use the same Security Principal as they are invoked by the Client.
