If you create a security realm with a duplicate name (such as geronimo-admin) using the admin console, everything appears to work in the ui however the command line console shows the error:

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.
