In the Manager, select the Unix | Groups category.
Select the group in the result list.
Select the Assign groups task.
In the Add assignments pane, assign the groups that are subordinate to the selected group.
TIP: In the Remove assignments pane, you can remove the assignment of groups.

Effectiveness of group memberships

Table 30: Configuration parameters for conditional inheritance
Configuration parameter	Effect when set
QER \| Structures \| Inherite \| GroupExclusion	Preprocessor relevant configuration parameter for controlling effectiveness of group memberships. If the parameter is set, memberships can be reduced on the basis of exclusion definitions. Changes to this parameter require the database to be recompiled.

When groups are assigned to user accounts an employee may obtain two or more groups, which are not permitted in this combination. To prevent this, you can declare mutually exclusive groups. To do this, you specify which of the two groups should apply to the user accounts if both are assigned.

It is possible to assign an excluded group at any time either directly, indirectly, or with an IT Shop request. One Identity Manager determines whether the assignment is effective.

NOTE:

You cannot define a pair of mutually exclusive groups. That means, the definition "Group A excludes group B" AND "Group B excludes groups A" is not permitted.
You must declare each group to be excluded from a group separately. Exclusion definitions cannot be inherited.
One Identity Manager does not check if membership of an excluded group is permitted in another group ( table).

The effectiveness of the assignments is mapped in the UNXAccountInUNXGroup and BaseTreeHasUNXGroup tables by the XIsInEffect column.

Example of the effect of group memberships

Group A is defined with permissions for triggering requests in a host A group B is authorized to make payments. A group C is authorized to check invoices.
Group A is assigned through the "Marketing" department, group B through "Finance", and group C through the "Control group" business role.

Clara Harris has a user account in this host. She primarily belongs to the "Marketing" department. The "Control group" business role and the "Finance" department are assigned to her secondarily. Without an exclusion definition, the user account obtains all the permissions of groups A, B, and C.

By using suitable controls, you want to prevent an employee from being able to trigger a request and to pay invoices. That means, groups A, B, and C are mutually exclusive. An employee that checks invoices may not be able to make invoice payments as well. That means, groups B and C are mutually exclusive.

Table 31: Specifying excluded groups (UNXGroupExclusion table)
Effective group	Excluded group
Group A
Group B	Group A
Group C	Group B

Table 32: Effective assignments
Employee	Member in role	Effective group
Ben King	Marketing	Group A
Jan Bloggs	Marketing, finance	Group B
Clara Harris	Marketing, finance, control group	Group C
Jenny Basset	Marketing, control group	Group A, Group C

Only the group C assignment is in effect for Clara Harris. It is published in the target system. If Clara Harris leaves the "control group" business role at a later date, group B also takes effect.

The groups A and C are in effect for Jenny Basset because the groups are not defined as mutually exclusive. That means that the employee is authorized to trigger requests and to check invoices. If this should not be allowed, define further exclusion for group C.

Table 33: Excluded groups and effective assignments
Employee	Member in role	Assigned group	Excluded group	Effective group
Jenny Basset	Marketing	Group A		Group C
Jenny Basset	Control group	Group C	Group B Group A	Group C

Prerequisites

The QER | Structures | Inherite | GroupExclusion configuration parameter is set.
Mutually exclusive groups belong to the same host.

To exclude a group

In the Manager, select the Unix | Groups category.
Select a group in the result list.
Select the Exclude groups task.
In the Add assignments pane, assign the groups that are mutually exclusive to the selected group.

- OR -

In the Remove assignments pane, remove the groups that are not longer mutually exclusive.
Save the changes.

Unix group inheritance based on categories

In One Identity Manager, groups can be selectively inherited by user accounts. For this purpose, the groups and the user accounts are divided into categories. The categories can be freely selected and are specified using a mapping rule. Each category is given a specific position within the template. The template contains two tables; the user account table and the group table. Use the user account table to specify categories for target system dependent user accounts. In the group table enter your categories for the target system-dependent groups. Each table contains the Position 1 to Position 31 category positions.

Every user account can be assigned to one or more categories. Each group can also be assigned to one or more categories. The group is inherited by the user account when at least one user account category items matches an assigned group. The group is also inherited by the user account if the group or the user account is not put into categories.

NOTE: Inheritance through categories is only taken into account when groups are assigned indirectly through hierarchical roles. Categories are not taken into account when groups are directly assigned to user accounts.

Table 34: Category examples
Category item	Categories for user accounts	Categories for groups
1	Default user	Default permissions
2	System users	System user permissions
3	System administrator	System administrator permissions

To use inheritance through categories

Define the categories in the host environment.
Assign categories to user accounts through their master data.
