The group name cannot exceed eight characters and longer names will be truncated to the first eight characters. For more information about the entry fields, please refer to the page help for the screen.
The permissions are displayed in an inverted tree structure. Those on lower branches include the permissions on the branches from which they descend. For example, the permission to restore a repository includes the permission to import a repository. Therefore, restore is shown as a descendant of import.
When you grant a particular permission, any permissions that it includes are automatically granted. Hence, when you check the Restore Repository permission, the Import Repository permission is automatically checked as well.
Where a check box for a permission is greyed out, it indicates that the permission is included by other permissions that have been granted to the group. To revoke a permission that is included by others, you must first revoke those other permissions.
