CallerPrincipal when calling one sessionbean from another

Question

Hi all,
I have a little problem when calling one sessionbean from another sessionbean. The problem is, that in the method, which is called, is used SessionContext's getCallerPrincipal().getName(). This works great from client, but from other sessionbeans getCallerPrincipal() retuns an "ANONYMOUS" principal. How can I set the correct principal (the principal from the first sessionbean)?
Thank you
My env: Glassfish 2.1.1, Netbeans 6.8, Eclipselink 2.0.0, Java 1.6.0.18
My code:
@Stateless
public class ABean implements ASessionRemote{
@Resource
SessionContext ctx;
@Override
public void aMethod(){
String name = ctx.getCallerPrincipal().getName(); // the name is ANONYMOUS, when the call is done from other sessionbean
@Stateless
public class BBean implements BSessionRemote{
@Resource
SessionContext ctx;
@EJB
private ASessionRemote aSessionBean;
@Override
public void bMethod(){
aSessionBean.aMethod();
}

"This works great from client"
What do you mean by this, i.e what sort of client are you using (stand alone app, servlet) ?
what shows up if you printout the caller principal in the calling bean ?
are the two ejbs in the same ear ?
what security meta-information are you using in ejb-jar.xml and sun-ejb-jar.xml, if any ?
