Not necessarily, you could be using port 139 for wbinfo, but winbind
could be using port 445 and this is blocked, it is worth checking.

Providing winbind is running, smb.conf is set up correctly, the winbind
links are installed and /etc/nsswitch.conf is set to use winbind, (all
of which seem to be correct on your machine) you should get users and
groups from AD, so if it isn't working, you need to check other things.
