[support] login page redirect elsewhere?

[sander-martijn]

I'm trying to get the successful login page to redirect to other pages 
than the uesr profile page - but the menu item says "locked" and I can't 
find a setting for it.  Can I use something like taxonomy_redirect for 
this?  Ideally it would be configurable per role - so an extranet user 
would go to an extranet page where an intranet user would go to an 
intranet page.
