You can create Oracle Identity Cloud
                                Service users to add to Oracle Cloud
                                Infrastructure IAM groups for specific access. To simplify access and
        permission management, grant permissions to groups instead of directly to users.
               
- Open the Oracle Cloud
                                Infrastructure navigation menu and click
                        Identity & Security. Under
                        Identity, click
                    Federation.
 
- On the Federation page, select the
                        OracleIdentityCloudService link to view the default
                        Oracle Identity Cloud
                                Service federation.
 
- Click Create IDCS User.
 
- Complete the fields to identify the user. In the Groups
                    field, select the IDCS group you want this user to belong to.
 
- Click Create.
A message is displayed that the user was created. Optionally,
                    click the Email Password Instructions button to email a
                    change password link to the new user. 
                     
The new user is displayed in the table of users. Notice that the
                        user's federation was automatically triggered if the user was added to a
                        federated IDCS group, and is displayed in the OCI Synched
                            User column.
