Well with IDM 4 this fits really well.
What we need is for someone in the Package team at Novell to go integrate this into the Packages for the AD driver.
This is where Packages will get really cool. Since before you had one configuration. Then you got Packages, where in theory you could select a subset of features.
Now we add a CHOICE between two feature models. However migrating between the two would not work, so that adds a complexity. I need to nag the people I know who do the Packages about this idea.
What makes this tricky is that the policy that needs altering spans at least three Packages (though I would have to go back and look to check), which is not something the model is good at supporting yet. But remember that Packages is really a 1.0 release, they have many good ideas to add still, and many they do not yet know they need.
