Get the "security" tutorial working on JBossAS-5.0 GA

Right now, the security tutorial fails to access the secure EJB with the following exception:

There has been a change in JBoss-5 in the way a standalone client can propagate user credentials to the EJB hosted on the server. The changes have been mentioned in this forum thread http://www.jboss.com/index.html?module=bb&op=viewtopic&t=144021. However, that does not seem to be working with JBoss-5.0 GA.

This issue is for identifying the root cause and fixing the same.
