Can I setup RTC with LDAP and create non-LDAP users?

 Michael, you can create any user you want in the repository. The issue is that the Application Server is doing the Authentication and passing the userid to Jazz. So we need the application server (Tomcat or WebSphere) to authenticate both group. For that I recommend Federated User Registries in WebSphere. This allow the authentication to work with 2 user registries (your LDAP for internal users and the 'other' registry for external users)
