One Identity Manager supplies employees in a company with company resources, for example, permissions or applications, according to their function. To do this, the company structures are represented in hierarchical role form in One Identity Manager.
Roles are objects through which company resources can be assigned. Employees, devices, and workdesks are assigned to roles as members. Members can obtain their company resources through these roles when One Identity Manager is appropriately configured.
Company resource assignments are not made to individual employees, devices or workdesks but centrally and then inherited automatically through a predefined distribution list.
In One Identity Manager, the following roles are defined for mapping company structures:
Departments, cost centers, locations, and business roles are each mapped to their own hierarchy under Organizations. This is due to their special significance for daily work schedules in many companies.
Business roles map company structures with similar functionality that exist in addition to departments, cost centers, and locations. This might be projects groups, for example. For detailed information on business roles, see the One Identity Manager Business Roles Administration Guide.
||NOTE: This function is only available if the Business Roles Module is installed.|
Application roles are used to grant edit permissions to theOne Identity Manager objects to One Identity Manager users. For detailed information, see the One Identity Manager Authorization and Authentication Guide.
Hierarchies can either be created following the top-down or the bottom-up model in One Identity Manager. In the top-down model, roles are defined based on the area of activity and the company resources required to fulfill the activities are assigned to the roles. In the case of the bottom-up model, company resource assignments are analyzed and the roles result from this.
The direction of inheritance decides the distribution of company resources within a hierarchy. One Identity Manager basically recognizes two directions of inheritance:
Top-down inheritance maps the standard structure within a company in One Identity Manager. With its help, a company’s multilevel form can be represented with main departments and respective subdepartments.
Whereas in "top-down" inheritance, assignments are inherited in the direction of more detailed classifications, "bottom-up" inheritance operates in the other direction. This inheritance direction was introduced to map project groups in particular. The aim being, to provide someone coordinating several project groups with the company resources in use by each of the project groups.
NOTE: The direction of inheritance is only taken into account in relation to the inheritance of company resources. The direction of inheritance does not have any effect on the selection of the manager responsible. The manager with a parent role is always responsible for all child roles.
The effect on the allocation of company resources is explained in the following example for assigning an application.
In the diagram above a section of a company’s structure is illustrated. Applications assigned to the respective departments are also entered. An employee in retail is assigned all the applications that are allocated to their department and all those on the full structure path. In this case that is internet software, address administration, mail, and text editing.
Figure 1: Assignment through Top-Down Inheritance
The next figure shows bottom-up inheritance based on a project framework. Applications assigned to the respective project groups are also entered. An employee from the project group "Project lead" receives applications from the project group as well as those from the projects groups below. In this case, it is project management, CASE tool, development environment, assembler tool, and prototyping tool.
Figure 2: Assignment through Bottom-Up Inheritance
There are particular cases where you may not want to have inheritance over several hierarchical levels. That is why it is possible to discontinue inheritance within a hierarchy. The point at which the inheritance should be discontinued within a hierarchy is specified by Block inheritance. The effects of this depend on the chosen direction of inheritance.
The Block inheritance option does not have any effect on the calculation of the manager responsible.
If the option Block inheritance is set for the department "Sales" in the top-down example, it results in sales employees being assigned address administration and employees in the retail department, address administration and internet software, but neither is assigned mail or text editing applications. Applications in the department "Overall organization" are, however, not assigned to retail and dealers.
Figure 3: Discontinuing Inheritance Top-Down
An employee from the project group "Programming" receives applications from the project group as well as those from the projects groups underneath. in this case, the development environment, assembler tool and the prototyping tool. If the project group "Programming" has labeled with the option Block inheritance, it no longer passes down inheritance. As a result, only the CASE tool is assigned to employees in the project group "Project lead" along with the application project management. Applications from the projects groups "Programming", "System programming" and "Interface design" are not distributed to the project lead.
