Your crystal ball must be pretty good because changing the winbind enum
user and group entries to "no" did the trick. The man page isn't very
specific about this change. Are they any downsides to this setting?

You mention LDAP traffic but you say nothing about what the
traffic is actually doing nor do you give any details of how you
server is configured. You could be using nss_ldap for all I know.
Just gazing into my crystal ball, I would ask whether or not
you have set 'winbind enum users = no' and 'winbind enum groups = no'?
If not, then do this first.
Then it would helpful to know more about your server.
