Figure 1 Process of granting an IAM user the OBS permissions

A user group is a collection of users. By assigning permissions to a user group, you assign permissions to the users in this group. After you create an IAM user, add it to one or more user groups, so that it can inherit the permissions from the groups. The user group is displayed in the user group list once the creation is complete. In the policy content area, you can view the authorization details. Due to data caching, an RBAC policy or a fine-grained policy involving OBS actions becomes effective 10 to 15 minutes after being attached to a user, enterprise project, or user group.
