Federated Insall; Share Permission

Hello,

I install two oC in different locations via Federated option;

I want to user cannot acces files in two location; if a user want to acces file different location; group admin must be approve this request;

How can i handle this?

Not directly possible. You could use the file firewall (only in enterprise version, or a ownCloud fork provides this option as well) to control the access of certain files within a certain IP range.
Or if group-admin is the owner of the file or shared directory, he can manually assign people who can access it.

Thanks,

They provide 30 day test images: https://owncloud.com/download/

Not sure if their module works exactly the same: Nextcloud

You can only move all files from a user to a different one: https://doc.owncloud.org/server/9.0/admin_manual/configuration_server/occ_command.html#file-operations

It's probably better to do it the other way round, use the admin-user to share a storage to users. Then you can decide to whom it is shared. If you set the personal quota of the user to 0, they can only write in these shared storages.
