rights for subjects and to objects

subjects and or objects

- Permissions for individuals within a group can still
be altered without changing the group permissions

to the role that is created
- Subjects are then
assigned a role
- administrator role will allow you to
perform most functions
- Clerk role will have
limited functions

segregation of duties
- Groups Vs Roles
- group is a collection of users and is really a
vehicle to simplify the administration of user's
access rights.
- role is a collection of access rights (or permissions) and hence pertains to
what users are permitted to do. The concept of a role fits very well into a
hierarchical organisation.
