This requires being able to list users from remote instances. Our graph DriveRecipients use the ObjectId and a LibreGraphRecipientType ... which is used to differentiate users and groups ... we could use "remote_user" and "remote_group" ...

The cs3 Gateway has a FindAcceptedUsers in addition to FindUsers. It uses the OCMInviteManager which is filled by invite requests.

But how are invites actually sent out? I don't see ui ... maybe part of sciencemesh. Needs further investigation. Maybe with curl requests for now ...

These users would then have type UserType_USER_TYPE_FEDERATED.

I still need to wrap my head around this further ...

This has been done. QA findings need to create new tickets.
