Default Groups 

Definition

In addition to the groups defined in the user data source(s), three default groups are determined dynamically at runtime and are not defined in the user data source(s). These are

·        Everyone: This group is the sum of the groups Anonymous Users and Authenticated Users.

·        Anonymous Users: This group contains all named anonymous users that are listed in the ume.login.guest_user.uniqueids property in UME Properties.

·        Authenticated Users: This group contains all non-anonymous users, that is, users that have to authenticate themselves to access an application.

The following diagram illustrates the relationship between the groups.

You can change the names of the default groups in UME properties. For more information, see Default Groups. Changing the name of these groups has no effects on portal permissions already assigned to these groups. You do not have to reassign the permissions to the new names.

You should not create groups with the names of the default groups, that is Everyone,  Authenticated Users, and Anonymous Users. If you create a group with one of these names through the native user interface of your LDAP directory or database, you will not get an error message, and your user management will no longer function correctly. If you try to create a group with one of these names through the user management administration console, you will get an error message.

In addition, the SAP J2EE Engine creates the standard groups Administrators and Guests. See Standard Users and Groups.
