How to enable options based on role via portlet.xml

Trying to figure out if it's possible to have roles to determine if the maximize, minimize, edit, view, config, etc. states are able to be setup for only certain roles.

EXAMPLE:

Config (user.isinrolle = Admin)
Edit (user.isinrolle = Manager)

This functionality is normally provided by the portal. The administrator can configure, which user group is allowed to change to edit/config etc. mode. Which portal server do you plan to use?

We're using Sun Portal v7, but I didn't see that in the configuration. We can setup based on Org who gets what tabs, content, portlets, etc. but I didn't see anything in there about managing the various options...
