I am facing a similar problem; Per the instructions in the http://wiki.jboss.org/wiki/Wiki.jsp?page=UsingCustomPrincpalsWith, I set up the login module that extends from UsernamePasswordLoginModule, configured it in the login-config.xml (with the principalClass option set to point to my custom principal). request.getUserPrincipal returns my custom principal but ejbContext.getUserPrincipal returns a SimplePrincipal. What am I missing? Any help will be greatly appreciated. side note: I am debugging into the JBoss source code but I am having to use the 4.2.1 source code because I am unable to locate the security source in the 5.0.0-beta3 or beta4 source code (for jbosssx.jar) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4134187#...
