There are several ways to share bucket data with other people.
In this page we will set up permissions on a bucket of the common tenant to allow any user of pac1 tenant to read and list data in the bucket "wo1".
In the cloud console go to "Object storage service".
In the upper right corner, click on your user name and select "My credentials"
Get the DomainID of your tenant:
CLick on the button "Add bucket policy".
In the popup window, select "read-only" or "read/write" following what access level you want to give.
Then in the zone "Principal" select "Other account" and in the first field paste your domain ID.
Enter "*" in the field resource.
Now people of the tenant "DomainID" can read (or read/write) data in the bucket (but they still cannot list items)
To enable object listing, add another policy as follows.
In "Policy mode" select "Customized", effect = "Allow" and in the Principal the domainID as previously.
Now in "Action" select the 3 options for listing as in the picture below.
