Virtual Users and Groups
This section describes the following virtual users and user groups topics:
The portal supports predefined virtual users and groups that allow for access control configuration that applies to abstract sets of users. These virtual users and groups are not stored in the user registry. They only exist within the access control context. You cannot change group membership or other attributes of these virtual users and groups.
Anonymous Portal User
This virtual user models a portal user that has not yet logged into the portal. Roles assigned to this user allows establishing pages and portlets that can be accessed prior to completing an authentication form. This is useful for creating public welcome pages. The Anonymous User is considered not to be a member of any group within the portal. Permissions on the anonymous user are derived from permissions on the virtual resource Users.
All Authenticated Users
This virtual user group models the set of all users that are known by portal. After successfully logging in to the portal, users lose the Anonymous Portal User identity and become authenticated users. These authenticated users are members of the All Authenticated Users virtual user group. Roles assigned to this user group allows establishing the permissions that will apply to all authenticated users and thus supports the setting up the default privileges within the portal.
All User Group
This virtual user group contains all non-virtual user groups.
