Hi, I have [1] a self written ClientLoginModule (reading a X.509 certificate) a [2] ServerLoginModule. The Transport is done using SecurityAssociation, on the ServerLoginModule I want to change/replace the Principal and I want the LoginContext on the client side to know about the changed principal? So, can I use the SecurityAssociation for sending data back from Server to Client? Regards, Darko View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4157665#...
