Figure 18-4 Controlling who can access portal areas
Each area page can be thought of as, and is, analogous to a team site. Just like
team sites, portal areas can inherit permissions from their parent area or can have
inheritance canceled by administrators. However, the method to cancel inheritance
for portal area pages is very different from the way it is done on team sites. All the
administrator needs to do is change the list of users and site groups that appears on
the area page by adding or removing a user or site group, which effectively cancels
inheritance for that portal area.
Tip Always read the description at the top of the portal area page to determine
whether inheritance is in effect or has been blocked. Figure 18-5
shows the News area page with inheritance turned on. If the administrator
turns inheritance off by changing the list of users and site groups, the
description will state “these permissions are not inherited” and will also
offer a link. Keep in mind that if you re-enable inheritance by selecting the
link labeled “Inherit permissions from the parent area”, you will lose any
changes you’ve made to the list of allowed users and site groups.
