IAM Policy

An administrator account can configure permission policies for user groups in IAM. Table 1 lists the default permission policies.

On the console homepage, select Identity and Access Management, and click User Groups in the navigation pane on the left. Locate the user group that you want to authorize permissions. Click Modify under the Operation column. In the User Group Permissions area, find the OBS (S3) project and click Modify to authorize permissions to the user group.
