[Samba] Ping to winbindd failed

[Mantrid]

Hi,

After upgrading to Samba 3.3.10 (Mandriva 2009.0), I'm unable to use wbinfo to
do anything. Previous to the upgrade, it was working fine. I upgraded to support
a new Windows 2008 R2 server (previously Windows 2000).

# wbinfo -p
Ping to winbindd failed
could not ping winbindd!

# ps -A|grep winbind
31955 ?        00:00:00 winbindd
31962 ?        00:00:00 winbindd

The "net ads" commands all work fine (user, net, etc.) and I've re-run "net ads
join" again, which succeeded.

I've been searching for the answer to this for a couple of days, without luck.
Hope someone can shed some light on what's gone wrong.

Cheers,
Mantrid
