David Jencks commented on GERONIMO-4553:
----------------------------------------

I experimented a bit with scoping security realms to an apps parents.  This is 
pretty straightforward for jetty7, slightly less so for jetty6, I'm not sure 
about tomcat, and AFAICT impractical for openejb at this time.

The problem with openejb is that authentication happens independently of which 
app you are dealing with, for instance when trying to get the ejb remote 
initial context.

I'll probably commit my jetty7/jetty6 work and keep thinking about openejb and 
tomcat.

> IMO we should allow users to create such duplicate realms but not try to 
> start them but rather show instructions on how to substitute their realm for 
> the existing one, namely:
> - edit var/config/config.xml to have load="false" for the plugin with the 
> existing security realm
> - edit var/config/artifact-aliases.properties to use the new plugin instead 
> of the old plugin
> - edit var/config/config.xml to start the new plugin (this is probably 
> unnecessary as the new one will probably be started due to dependencies)
> I tried this on trunk and a user found it on 2.1.2.
