About groups
For information about creating and editing groups refer to Manage groups.
Hierarchy
Groups can be children of another group. Members of children groups are effective members of the parent group.
When you bind a group to an application or flow, any members of any child group of the selected group will have access.
Recursion is limited to 20 levels to prevent deadlocks.
Attributes
Attributes of groups are recursively merged, for all groups the user is a member of. For more information, see Group properties and attributes.
