Access denied

Problem Description: When my IAM User accesses a cloud service, the system shows a "No Permission" error.

  1. Please check the list of currently supported product lines of Baidu AI Cloud to confirm whether the product supports IAM user permissions and understand the permission granularity in detail.[Currently supported product lines](IAM/Product Description/Currently Supported Product Lines.md)

  2. Check whether you have the necessary permissions for the operations and resources you are attempting to access.

    • [IAM user permissions](IAM/Operation guide/User/User management.md)
    • [Group permissions](IAM/Operation guide/Group Management.md)

Note: In group management, adding users to new groups allows them to inherit group policies while retaining their individual policies.
