Our test suite has test(s) for container configurations and security domain defined in container configs (jboss.xml). I am surprised that you have this issue. Try with AS5.1.0. I am not saying that your issue is solved. You can first try to create a sample ejb project (ejbs) and reproduce the failure. After that, you can create a jira issue in JBAS and attach the sample project to the jira for a faster resolution.
