Problems calling Secured EJB remotely from a Standalone client in EAP 6

Issue

• The EJB is configured with @SecurityDomain and the @RolesAllowed Annotation.
• When the Username/PAssword is provided programmatically using the InitialContext the authentication is not working but when it is the same is included into the jboss-ejb-client.properties the authentication is successful.
• When the EJB Secured method is invoked, the $local Principal is seen in the Server Console and logs, but the authentication does not happen.
• On invoking the Secured EJB method with @RolesAllowed, the Security Credentials do not seem to propagate but gives the name as anonymous as the Principal Caller in the Server console.
• On trying to invoke the Bean, the following exception is encountered:

 javax.ejb.EJBAccessException: JBAS014502: Invocation on method: public abstract <method_name> of bean: <Bean_name> is not allowed

• Geting following ERROR in JBoss. What does this following ERROR mean?

10:49:53,426 ERROR [org.jboss.as.ejb3.invocation] (Thread-265) JBAS014134: EJB Invocation failed on component TestPojoPersistence for method public example.UserClass example.TestPojoPersistence.get(java.lang.String,example.TestBean,example.TestUser) throws java.lang.Exception: javax.ejb.EJBAccessException: JBAS014502: Invocation on method: public example.UserClass example.TestPojoPersistence.get(java.lang.String,example.TestBean,example.TestUser) throws java.lang.Exception of bean: TestPojoPersistence is not allowed
