Subject: To winbind or not to winbind.

The subject pretty much says it all. I know that I need winbindd when
running Samba in ADS mode as a DMS to AD, otherwise nothing works right.

I was playing in Ubuntu 8.04.2 which has 3.0.28a (trying to stay pure on
this box) default winbindd on. Well, when I try to set ACLs on a file
(ext3, ea support on, acls and extended_xattr) with winbind on I get no
error when I apply the change, but the Windows XP side shows no change
but the Samba log shows:

[2009/03/11 18:39:22, 0] smbd/posix_acls.c:create_canon_ace_lists(1438)
  create_canon_ace_lists: unable to map SID

Then I turn winbindd off and everything is perfect - no problems, acl is
applied and the refresh on the Windows side concurs with the Ubuntu

Is this by design? I always thought that winbindd running was not a
hindrance, util now. In fact I thought I recalled a few threads where is
was recommended that winbindd run no matter what your setup.

Can someone elaborate or point to a place where I missed the

:-) :-)



Don't mean to jump on this but... is it necessary or recommended to have
Winbind running when your box is acting as an ADS member server?
You say nothing works right? Maybe this is the cause of some of the
inermittent issues I have..
Can anyone elaborate. I thought I did not need Winbind..I do not use it
and everything seems to work great but from time to time I get no
password server available to validate. Might not be related..
