Hi Gregorcy,
Here's what I sent along to Masao. I didn't cc the list either :-( So
here it comes now.
Hope it may be useful.

Did you have a legacy /var/lib/samba/winbindd_idmap.tdb lying around
from a previous active directory membership? If this computer had a
windows user called jdoe whos uid->sid mapping was stored in that
account, and you rejoined AD later on, you might cause yourself
problems when trying to change the "new" jdoe's passwd (e.g. his
unix
uid would be mapped to a different windows SID as I understand it). I
am a bit fuzzy on this, others could be of more help. I get around
this because I use a static rid mapping (e.g. idmap backend
rid:VANGUARD=10000-200000) so that I can scale AD accross servers and
uid->sid mappings stay consistent.

Here's what my ssh entry in /etc/pam.d looks like (note the entry for
winbind)
auth required pam_env.so # [1]
auth required pam_env.so envfile=/etc/default/locale
auth sufficient /lib/security/pam_winbind.so
@include common-auth
account required pam_nologin.so
account sufficient /lib/security/pam_winbind.so
@include common-account
@include common-session
session optional pam_motd.so # [1]
session optional pam_mail.so standard noenv # [1]
session required pam_limits.so
@include common-password

I believe you need krb5 to join AD but you don't need entries in
pam.d/common-* unless you are trying
to refresh kerberos tickets for various domain services. Again, others
would know more.
I messed
around with automatically refreshing users kerberos tickets, but I
couldn't get it working well, so users
just have to present credentials when they want to get a windows share
for example. I really should revisit this. :-)

winbind 3.0.28a-1ubuntu4.9
samba-common 3.0.28a-1ubuntu4.9

No I decided I didn't want to mess with the DC's in any way.

I think you are on the right track. Have you tried turning up the
verbosity on the logging? You can do that in the smb.conf file and
then try your transaction and check for messages in /var/log/samba
Here's a little blurb from O'reilly

I'll be interested to hear what you find out. I'm planning on
migrating to Lucid (the next LTS) sometime in the next 6 months, and I
would guess Karmic (9.10) and Lucid will be very similar with regards
to winbind and samba.
Btw, as an aside, I found out as long as I am only joining my servers
to AD and not actually hosting shares via samba on my Linux server, I
only need the winbind package on LTSP. Winbind installs a minimal
subset of the samba packages and doesn't run the samba daemon.
Good luck!
John
