If they log in to OBS Console or OBS Browser+ to perform those operations, a message will be displayed indicating that they do not have required permissions.</p>
|
|
<p id="obs_40_0023__p2095722518592">When they log in to OBS Console or OBS Browser+, APIs (such as <strong id="obs_40_0023__b34331469166">ListAllMyBuckets</strong> and <strong id="obs_40_0023__b13433194621618">ListBucket</strong>) are called to load the bucket list and object list and some other APIs will also be called on other pages, but their permissions do not cover those APIs. In such case, the message is diplayed.</p>
|
|
<p id="obs_40_0023__p7807163365117">To allow IAM users to operate buckets and objects on OBS Console or OBS Browser+, add at least the <strong id="obs_40_0023__b1611149202711">obs:bucket:ListAllMyBuckets</strong> and <strong id="obs_40_0023__b86122918270">obs:bucket:ListBucket</strong> permissions to the custom policy.</p>
