Depending on the selected S3 client, you have various options for sharing buckets, objects, or object versions with users of an S3 Object Storage. In addition to roles and predefined profiles, you can share the content of your buckets with selected users by using their S3 ID (so-called "ACL Sharing" or "S3 Sharing"). There are three separate forms of identification:
Contract-user-ID: The contract-user-ID consists of contract number and user ID (contract number|User UUID). In the Object Storage Management Console, this ID can be used for the sharing of objects with selected users of the entire IONOS S3 Object Storage (not limited to users of your own account).
S3 Canonical-user-ID: The Canonical User ID is the ID assigned to a user by the IONOS S3 Object Storage.
Email address: Some S3 clients only require the e-mail address of a registered S3 user for sharing objects as they are capable of converting the e-mail address to the ID required by the object storage.
S3 clients that support the "Display Name" feature will display the e-mail address instead of the ID of a user for better readability.
Retrieving your own S3 ID
In order for another user to share the content of their IONOS S3 Object Storage with you, they need your S3 ID, which you will find in the Object Storage Key Manager.
Prerequisites: Make sure you have the corresponding permission to create the Object Storage. Only contract owners and administrators with the Object-Storage-Key can set up the object storage.
Open Menu Bar > Resource Manager > Object Storage Key Manager
Open the S3 Sharings drop-down menu.
The Object Storage Key Manager contains your own personal S3 identification data.
The S3 IDs are displayed. You can now copy the required ID and tell the user who wants to share the content of their object storage with you.
Retrieving the S3 ID of another user
If you want to share the content of your IONOS S3 Object Storage with other users, you need their S3 ID.
Prerequisites: Make sure you have the corresponding permission to create the Object Storage. Only contract owners and administrators can retrieve the S3 IDs of their IONOS account users in the User Manager.
1. Open Menu Bar > Resource Manager > User Manager
2. In the Users tab, select the required user.
3. In the Object Storage Keys tab, open the S3 Sharings drop-down menu.
The S3 IDs are displayed. You can now copy the required ID and use it for sharing your objects with this user.
User S3 identification is located in the upper right corner of the Object Storage Keys tab.
