Description

The federation feature with trusted servers could be useful to exchange our user directory with partners for sharing files and autocomplete usernames across instances.

However partners would currently see all users including internal and external workers as the whole user directory is exchanged.

In our case the exchange process should either be limited a specific group that contains the internal users/workers only or it should exclude a specific group that contains the external users/workers.

Research direction

No file or test is named. Start by locating the trusted-server federation directory-exchange entry point and its existing tests; trace how the full user directory is selected. Done means the exchange can be limited to an included group or filtered by an excluded group, with tests covering the intended partner-visible users.
