r12847 r12849 4 4 ******** 5 5 6 Kofa has a very efficient security machinery. The machinery does not perform authorization checks on the content objects themselves stored in the database but restricts the usage of views, i.e. web pages and forms which are needed to view or edit data. Views are protected by permissions the user must have to use the view. Instead of assigning permissions seperately to users, permissions are bundled into sets of permissions, so-called roles which can be assigned to users through the web interface. 7 8 It is important to note that permissions do not include other permissions. Only roles 'include' permissions. A 'manage' permission, for example, does not automatically enable users to open pages which merely display the data. These pages have their own 'view' permission. Another example is the ManagePortal permission described below. The name of the permission may lead to believe that users can do everything with this permssions. This is not true. It does only give access to certain pages which are dedicated to portal managers and must not be accessed by any other user. 6 Kofa has a very efficient security machinery.

In contrast to local roles, users have this role in every context. 129 130 Many global roles do only bundle one or two permissions. The objective behind is to share responsibilities and distribute tasks. 146 Global or site roles are assigned portal-wide.

At first glance it appears strange that some of these 'odd' roles do not give more permissions than the user already has due to other roles. Their real purpose is to delegate permissions to the students or application section. If a user has for example the LocalStudentsManager role described below at department level, s/he automatically gets the StudentsManager role for those students studying in this department. We call this a **dynamic role**. In contrast to static global or local roles, dynamic roles are not stored in the database, they are dynamically assigned. 215 216 Local roles are assigned either automatically by the system during user object setup or manually through the web interface.
