Hello, I'm using Jboss 5 CR 2 and I have some problems with authentification using Jaas. I explained my problem here : http://www.jboss.com/index.html?module=bb&op=viewtopic&t=137149 To summary : I have EJB deployed, a client-side Jaas authentification and context propagation to the Jboss ClientLoginModule. On the server side, I retrieve the EJB Context and get the caller name. A first user is log in and perform operations on the EJB. It log out, and another user log in and perform some operations on the EJB too, but I get the old user name from the EJB Context. Did I miss something? Thanks in advance. Regards, -- Thomas Gueze
