Shared roster from another domain - how?

There are two Openfire 3.6.4 servers.

Each one is bound to an Active Directory domain (say “first.local” and “second.local”). Both domains trust each other.

Group sharing is used to fill rosters.

Is it possible to create a group in domain “second.local” which will contain some users from the “first local” so that Openfire can use this group for roster filling?

I tried to make a group (Security, Domain local) and add some users. I can see that users in Active Directory (marked with a little red curved arrow), but when I set up group sharing in Openfire, this group is ignored.
