[rules-users] Login Names for drools-5.0-guvnor installed on Tomcat 6

My question is related to Login Names for drools-5.0-guvnor installed on Tomcat 6. A Guvnor tutorial offers an example for JBoss AS on how to provide user name/password. Can you provide a similar example for the Tomcat 6 case? How to config 2-3 names for the admin role? I hope that the question is easy for someone who is already working in this environment. Thank you so much for your help, Jeff
