The PAF recognizes six distinct categories of user:
Anonymous User
Registered User
Community Guest
Community Member
Community Leader
Portal Administrator
Every portal user belongs to at least one of these categories. These groups also generally correspond to varying levels of access, features, and functionality. Users with higher security roles implicitly hold lower roles as well. For example, a community leader is also a community member and community guest (but not a portal administrator).
For administrative information on portal security (restricting access to communities, pages, and gears), refer to the Portal Access Control chapter of the Portal Administration Guide.
