Hello: Problem: I have created 2 secure web applications (war files) which share the same authorization roles. I am trying to implement single-signon with jboss-3.2.0_tomcat-4.1.24. I read that I need to configure the tomcat-service.xml file, but I am unable to find it in my deploy directory. (C:\jboss-3.2.0_tomcat-4.1.24\server\all\deploy) Also, I know there is a concept of configuring or setting the single-signon Valve, but I�m unsure of how to proceed. Thanks for any help you can provide. Claude.
