[Samba] cannot change file permissions

[Matthias Eichler]

Hi List,

I have some severe problem with Samba 3 with ldapsam
backend on debian stable.

The problem is that I can not change the rights
of a file or directory on the server from Windows.

I get this in smb.log:
---cut---
[2004/03/14 21:59:09, 0] smbd/posix_acls.c:create_canon_ace_lists(1380)
  create_canon_ace_lists: unable to map SID
S-1-5-21-2443489570-4015384086-1858331161-3009 to uid or gid.
---cut---

3009 is the correct rid(?) of the gid 1004.
This is also correctly mapped:
---cut---
Buchhaltung (S-1-5-21-2443489570-4015384086-1858331161-3009) ->
buchhaltung
---cut---

Unfortunately this also happens with users:
---cut---
[2004/03/14 21:56:37, 0] smbd/posix_acls.c:create_canon_ace_lists(1380)
  create_canon_ace_lists: unable to map SID
S-1-5-21-2443489570-4015384086-1858331161-3016 to uid or gid.
---cut---
In this case 3016 is the right rid for the user with the uid 1008.
But this user has also the correct attributes in ldap:
---cut---
#
# filter: uid=lf
# requesting: ALL
#

# lf, RDS, KERNZEIT, COM

Help is really appreciated as I am stucking with this problems for such
a long time now without any light at the end of the tunnel!

Thanks very much,
