<p id="obs_40_0025__p16477101313289">After the configuration is complete, the authorized account can perform read and write operations (upload, download, or delete all objects in a bucket) by using APIs or by adding external buckets through OBS Browser+. To do this by adding external buckets, the <strong id="obs_40_0025__b720124283">ListBucket</strong> permission is also required. Currently, access to buckets of other accounts is not allowed on OBS Console.</p>
|

<p id="obs_40_0025__p119511212513">After the ListBucket permission is configured, a message may still be displayed indicating that you do not have the permission to access the added external bucket through OBS Browser+.</p>

However, such operations are not allowed by the read and write permissions. Therefore, a message "Access denied. Check the response permission" or "This operation is not allowed on the requested resource" is displayed, however, existing permissions are not affected.</span></p>
