R: [Samba] Samba3 : no suitable range available for sid

I'm setting up a freebsd server which will authenticate against an
Active Directory
I mean: the server will NOT have any local users (except mandatory and
required for management and configuration) and will authenticate requests
for login and access
FOR EVERY SERVICE against an Active Directory Server

I have configured the samba service and currently I can
login to local terminal, ssh, smtp and pop3 services using local or AD users
and password. Each service authenticates correctly the user, first trying on
AD domain then, if failing, validating against local passwd db

The problem is that I get this error every 30 seconds

rid_idmap_get_id_from_sid: no suitable range available for sid: S-1-5-32-549

I get this message for every builtin group in Active Directory Domain
This error doesn't cause any problem or mulfunction to running services
(ssh, smtp, pop3,
But it's really annoying and causes log file to grow up in size very very

as far as I can understand Samba is trying to associate BUILTIN groups with
its local copy, but it doesn't have allowance for the operation (and in fact
I do not want this)

What can i do to stop this error from coming out every 30 seconds ?
What have I missed in the configuration so that Samba try to copy the
BUILTIN groups ?

Here is my smbd configuration
workgroup = mydomain
realm = mydomain.it
security = ADS
allow trusted domains = No
idmap backend = idmap_rid:DMSWARE= 1000-100000
idmap uid = 1000-100000
idmap gid = 1000-100000
template homedir = /home/%U
template shell = /bin/sh
winbind cache time = 3600
winbind nested groups = Yes
winbind use default domain = Yes
syslog only = Yes

# These scripts are used on a domain controller or stand-alone
# machine to add or delete corresponding unix accounts
add user script = /usr/sbin/pw useradd %u
add group script = /usr/sbin/groupadd %g
;  add machine script = /usr/sbin/adduser -n -g machines -c Machine -d
/dev/null -s /bin/false %u
  delete user script = /usr/sbin/pw userdel %u
;  delete user from group script = /usr/sbin/deluser %u %g
  delete group script = /usr/sbin/pw groupdel %g

and here is my PAM stack for /etc/pam.d/system

thanks for every help or hint you can give me.
