Modifying an Object User Permission Policy

Prerequisites

• An object user has been created.
• A user permission policy has been created.

Procedure

1. Choose Resources > Access > Authentication User > Object Users.
2. Select a desired account from the Account drop-down list in the upper left corner.
3. Click More on the right of the desired object user and select Manage User Permission Policy.

   The User Permission Policy page is displayed.

   

   You can also click the desired username to go to the details page and manage user permission policies.

4. Click More on the right of the desired user permission policy and select Details.

   The Modify User Permission Policy page is displayed.

5. Change the policy mode. Possible options are as follows:
   • Recommended: provides three policies.
     • Read-only: Authorized users can read bucket resources. This policy mode does not define the write operation permission. You need to determine the permission based on other policies (such as the bucket permission). For example, if the bucket permission is read and write, the user permission is read and write.
     • Write-only: Authorized users can write bucket resources. This policy mode does not define the read operation permission. You need to determine the permission based on other policies (such as the bucket permission). For example, if the bucket permission is read and write, the user permission is read and write.
     • Read and Write: Authorized users can read and write bucket resources.
   • Custom: configures related parameters as required.

     For details about how to set parameters for user permission policies, see the description of the PolicyDocument parameter in section Configuring User Policy in Object Service Account Management API Description of the corresponding version.

     

     • The policy content must be in JSON format and the total length of all policies for an object user can contain a maximum of 2048 characters. Example: {"Statement":[{"Sid": "self","Effect":"Allow","Action":[ "s3:List*","s3:Get*"],"Resource":"*"}]}
     • If the object user needs to use the temporary security credential service, set Action to the value in the example. Example: {"Statement":[{"Sid": "self","Effect":"Allow","Action":[ "sts:AssumeRole","sts:TagSession"],"Resource":"*"}]}

6. Click OK.
