I am having the exact same problem that thammoud described. I had the messaging system use my security realm but once I return from the JMS call, the getPrincipal().getName() returns the user specified by the unauthenticatedIdentity. Has anyone else ran into this issue and if so, were you able to resolve it? Thanks. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4252952#...
