Hi iRedMail Admins and Users,

I want to grant access rights to shared folders on a group basis.

Current state:

1) User marketing.shared@mydomain.com logs in to SOGo

2) User marketing.shared opens 'Sharing...' option from the Inbox' context menu

3) User marketing.shared can search for single users or provide access to all domain users (authenticated users)

4) If marketing.shared shares the Inbox to a single user (e.g. tom.jerry@mydomain.com), the marketing.share Inbox appears below tom.jerry's 'Other Users' directory in SOGo.

5) If marketing.shared shares the Inbox to a all authenticated users, the marketing.share Inbox does not appear below any domain users' 'Other Users' directory in SOGo

6) There's no option to select or search for groups you want the Inbox to be shared with. If you insert a groupname (e.g. disneycharacters@mydomain.com) into the search field for users, the group does not show up. If you insert the full groupname and save the input, the next time you open 'Sharing...' setting from the Inbox' context menu, the disneycharacters@mydomain.com is being displayed in the enumeration of granted accounts, but it does not take effect. Checked it with user mickey.mouse@mydomain.com being member of the group disneycharacter@mydomain.com.

The question is: How can I make 6) work?

Thanks in advance!
