[Samba] Limit user authentification into Winbind ?

[Noc Phibee]

Hi

i see on my log, two informations :


1- Into my log, i see a very big quantity of :
  [19391]: lookupname ECTPP/root
[2005/12/09 14:28:46, 3] 
nsswitch/winbindd_async.c:winbindd_dual_lookupname(695)
  [19391]: lookupname ECTPP/root
[2005/12/09 14:28:46, 3] 
nsswitch/winbindd_async.c:winbindd_dual_lookupname(695)

10x per s .... 600x/minutes .. it's very very big no ?
It's possible that is Spamassassin that create this request ?
i use winbind only for squid, can i del into pam winbind for no other 
process use it ?

2- Into my log, i have a new logs created :
       log.wb-BUILTIN
i see that winbind create a log file for each domain, but i don't have
a domain BUILTIN

and i have into this files a big quantity of this line :
