Let's take an example:
Users
TOS Configuration
- Media discovery: on
- Folders | Allowed access:
- /homes/admin/photos | admin
- /homes/user1/photos | admin, user1
- /public_shared_folder/photos | admin, user1
- /private_shared_folder/photos | admin
Photos Configuration
- AI face recognition: on
- AI scene recognition: on
When I connect to Photos as
admin, I can see everything.
When I connect to Photos as
user1, I checked if user rights were respected under private/public spaces :
- Photos: ok
- Videos: ok
- Folder: ok
- People: ok
- Scene: NOT OK
- Places: NOT OK
From Scene or Places, user1 can access photos that are not supposed to be accessible to them. More specifically, it seems user1 can see photos that are under
/private_shared_folder/photos while
/homes/admin/photos isn't accessible at all.
List of issues
- Users can find photos in Scene and Places that shouldn't be accessible to them
- "Added recently" category is always empty
- If I set people's name (from AI recognition), it doesn't affect other users on the same photos (but that could be intended)
I hope it gives you more details and helps you digging into the issues.

Don't mind if you have any other question !
