[Samba] Limit Winbind authentication requests>?

[alaslavic at havertys.com]

Quick question, is there a way to limit how aggressively winbind attempts
to authenticate users?  I have seen instances where an authentication
request for the same user happens 20 times in a second.  This happens
especially for failed authentication.
