Description
Steps to reproduce
- Share an address book from one user with a NC user group (e.g. group “team”)
- Check with a user in that group if the AB shows in the UI (e.g. user “Anne”)
- Share the same AB directly with that user (“Anne”) and check again
Expected behaviour
If I share an address book with a NC user group, all users within that group should see the shared address book in the contacts app.
This worked in my NC 10 installation, but I don't know which prior version of Contacts was installed.
Actual behaviour
If I share with the group, the AB does not show up in a user's contacts list. If I share the AB with the same user, but this time directly with his username, the AB shows up correctly.
