I'm using a slightly modified copy of the Multi Site User Management plugin to keeps users synced across a multisite network, but have one problem with it. When a user's role is updated on the main site, the role is NOT updated on the sub site. In order for everything to work correctly, user roles must stay in sync.
I've been looking without success, so is there an action that runs when a user is updated? I know about the profile_update and wp_update_user functions / hooks, but neither of these work because the user role is updated via an external function. So I need a new way of always syncing user roles.
