Additional tasks for managing SharePoint groups

After you have entered the main data, you can run the following tasks.

Displaying an overview of SharePoint groups

Use this task to obtain an overview of the most important information about a group.

To obtain an overview of a group

  1. Select the SharePoint > Groups category.
  2. Select the group in the result list.
  3. Select the SharePoint group overview task.

Effectiveness of group memberships

When groups are assigned to user accounts an identity 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.

The effectiveness of the assignments is mapped in the SPSUserInSPSGroup and BaseTreeHasSPSGroup tables by the XIsInEffect column.

Example: The effect of group memberships
  • The groups A, B, and C are defined in a site collection.
  • Group A is assigned through the "Marketing" department, group B through "Finance", and group C through the "Control group" business role.

Jo User1 has a user account in this site collection. They primarily belong to the "Marketing" department. The "Control group" business role and the "Finance" department are assigned to them 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 identity from obtaining authorizations of groups A and group B at the same time. That means, groups A, B, and C are mutually exclusive. A user, who is a member of group C cannot be a member of group B at the same time. That means, groups B and C are mutually exclusive.

Only the group C assignment is in effect for Jo User1. It is published in the target system. If Jo User1 leaves the "control group" business role at a later date, group B also takes effect.

The groups A and C are in effect for Chris User2 because the groups are not defined as mutually exclusive. If this should not be allowed, define further exclusion for group C.

Prerequisites

  • The QER | Structures | Inherite | GroupExclusion configuration parameter is set.

    In the Designer, set the configuration parameter and compile the database.

    NOTE: If you disable the configuration parameter at a later date, model components and scripts that are no longer required, are disabled. SQL procedures and triggers are still carried out. For more information about the behavior of preprocessor relevant configuration parameters and conditional compiling, see the One Identity Manager Configuration Guide.

  • Mutually exclusive groups belong to the same site collection.

To exclude a group

  1. In the Manager, select the SharePoint > Groups category.

  2. Select a group in the result list.

  3. Select the Exclude groups task.

  4. 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 no longer mutually exclusive.

  5. Save the changes.

SharePoint group inheritance based on categories

In One Identity Manager, user accounts can selectively inherit groups. To do this, groups and 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 category positions position 1 to position 63.

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 30: 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

Figure 3: Example of inheriting through categories.

To use inheritance through categories

  1. Define the categories in the site collection.
  2. Assign categories to user accounts through their main data.
  3. Assign categories to groups through their main data.
