 Get a list of the names of all users of this machine who are

 This should return a list of the users on this machine who are
 logged into the domain (i.e. have been authenticated by the domain's
 password server) but that doesn't fit well with the normal Samba
 scenario where accesses out to the domain are made through smbclient
 with each such session individually authenticated. So about the best
 we can do currently is to list sessions of local users connected to
 this server, which means that to get themself included in the list a
 local user must create a session to the local samba server by running:
     smbclient \\\\localhost\\share

 FIXME: find a better way to get local users logged into the domain
 in this list.
