[Samba] Problem with Redhat 8 and access control of files

Thu, 14 Aug 2003 16:32:56 -0700

I have a RH8 and samba version 2.2.7-security-rollup-fix. The problem is I can't change the permissins of files from Windows clients (NT and 2000). If I am logged as some user, create a file on some share and then try to change its permissions (for example trying to add read access to Everyone) it responds with Access denied. I have almost the same setup on another test machine with Gentoo Linux and Samba 2.2.8 and it works perfectly. I don't use posix acl, just the default unix permissions. This is what the log output shows:

[2003/08/12 10:59:16, 2] smbd/open.c:open_file(245)
user opened file RFC/rfc1.txt read=Yes write=No (numopen=2)
[2003/08/12 10:59:16, 2] smbd/posix_acls.c:set_canon_ace_list(1764)
set_canon_ace_list: conn->vfs_ops.sys_acl_set_file type file failed for file R
FC/rfc1.txt (Operation not supported).
[2003/08/12 10:59:16, 2] smbd/close.c:close_normal_file(213)

And my smb.conf

workgroup = Mydomain
server string = My Server
hosts allow = xx.xx.xx.0/255.255.255.128
printcap name = /etc/printcap
load printers = yes
printing = lprng
log file = /var/log/samba/%m.log
max log size = 50000
log level = 2
security = domain
password server = PDC BACKUPDC
encrypt passwords = yes
smb passwd file = /etc/samba/smbpasswd
local master = no
os level = 33
dns proxy = no
default case = lower
winbind separator = @
winbind uid = 10000-30000
winbind gid = 10000-20000
admin users = [EMAIL PROTECTED]
#============================ Share Definitions ==============================
[homes]
comment = Home Directories
browseable = no
writable = yes
path = /home/Mydomain/%U
create mode = 0700
directory mode = 0700
guest ok = no

[Mydomain]
  comment = Admin Share
  writable = yes
  valid users = [EMAIL PROTECTED] @"[EMAIL PROTECTED] Supervisors"
  path = /home/BNSA
  guest ok = no

[printers]
  comment = All Printers
  path = /var/spool/samba
  browseable = no
  public = yes
  writable = no
  printable = yes

[public]
  comment = Public Stuff
  path = /home/public
  public = yes
  writable = yes
  printable = no
  guest ok = no

[docs]
  comment = Linux Docs
  path = /usr/share/doc
  public = no
;   browseable = no
  writable = no
  valid users = list of users
  printable = no
  guest ok = no
  write list = [EMAIL PROTECTED]

What could be the reason of this behaviour and how can I solve the problem?
