cas + EJB + websphere

[m.garuti at quix.it]

hi,

I'm using cas server 3.2 and cas client 3.1.1.
I have deployed all on websphere 6.1 and installed a test EAR 
application with a Servet that call an EJB.
The web application is under CAS Filter.

I see the correct remote user inside the servler but inside ejb, the 
principal is always null 
(javax.ejb.SessionContext.getCallerPrincipal().getName())

Does anybody tried this configuration under websphere?
Is prossible to propagate principal from web-container to EJB-container 
when using CAS Client filter?

thanks in advance
paco
