I am trying to understand the difference between SlideRealm and JAAS. I would like to have authentication completely handled by Tomcat so that I can defer to an LDAP Directory, and I would like for Slide to create users automatically with default access. For additional access I would like for Tomcat to use Slide's groups and/or permissions to manage access to other parts of the web application (forums, calendars, etc.). 1) Can slide be used to manage roles/groups for a web application while letting Tomcat manage authentication? 2) What would be the best approach to build with what Slide has now? 3) Am I correct that only SlideRealm keeps Slide groups synchronized with Tomcat roles, and that only JAAS can be used outside of Tomcat? 4) What are the other differences between SlideRealm and JAAS? 5) Are roles still a part of Slide or only groups? Thanks, Ryan Rhodes
