I think the idm module is always necessary, it defines the core identity 
model which the federation module *should* eventually consume anyway 
once we work some more on integration.  Any other dependencies of the 
config module (like the federation module) should be defined as optional 
in the pom.

So are you suggesting we merge common and config?
