[Samba] Inefficient Winbind behavior?

I believe you can tell when the server joins the domain what the PDC is
(just make it the LOCAL BDC)....  also maybe an option in smb.conf.  Sounds
like the delay could be while winbind is updating.  Have you done the getent
passwd or getent group?  how long does it take to pull through winbind?

Subject: [Samba] Inefficient Winbind behavior?

Hello all,
I'm having an issue with Winbind and I'm not sure if it's occurring by
design or not.
My Samba server resides in a Windows NT domain and uses winbindd to
authenticate to a mixed-mode 2003 domain over a trust relationship.
Everything works the way it ought to.  However, every so often my users
experience delays of anywhere from 30 to 60 seconds when connecting to a
share, instead of the share being instantaneously available, as is normally
the case.  
I've done some investigating and have found that winbindd queries WINS for a
domain controller for the 2003 domain, which it finds just fine and is able
to authenticate users against.  However, the problem is that the server it's
finding is on a different subnet, connected via a T1 WAN link.  So it uses
the remote server instead of a local 2003 DC, which is acting as a BDC, that
resides on the same LAN as the Samba server.  
Shouldn't winbindd use the local DC?  Can I configure it to do so?  I'm
fairly convinced that authenticating over the WAN link is causing the delays
I'm experiencing.  Any ideas are welcome.
Thank you.
