Robert, yes, it works and is what i want, exactly.
There is small issue, however. - Primary groups didn''t supported in current code. So, for example, if user1 has 'group1' as its primary group (set in /etc/passwd) he will be filtered out. Can you please improve in_group () method with smth like:

    private bool in_group (string group_name, string user_name)
    {
        unowned Posix.Group? group = Posix.getgrnam (group_name);
        if (group == null)
            return false;

        /* Check if user has group_name as it's primary group  */
        unowned Posix.Passwd? pw = Posix.getpwnam( user_name );
        if( pw.pw_gid == group.gr_gid )
            return true;

        /* Check if group_name is user's auxilary group */
        foreach (var name in group.gr_mem)
            if (name == user_name)
                return true;

        return false;
    }

Title:
  Support for 'list members of group(s) only'

Status in unity-greeter package in Ubuntu:
  Triaged

Bug description:
  It would be great to have "/com/canonical/unity-greeter/hidden-users"
  counterpart with revert logic.

  In our project we need the greeter shows members of some group(s)
  only.

  We can't delegate this work to lightdm or accountsservice because this
  can break login/policy/accounting system. - Our goal only is to get
  occasional/admin users of workplace out of greeter's 'users board'.

  To achieve this we had to change current unity-greeter code.
  We publish branch here: lp:~dmzavr/unity-greeter/unity-greeter

  Can we expect the requested feature will be supported in some future
  release?
