I have a SAMBA server with ROLE_DOMAIN_MEMBER in Active Directory. My main aim is to make a different permissions on share sub-folders on very single share. It can be done using Linux acl or Windows permissions GUI. But I prefere a Windows GUI. In this case users can do this by themselves.

I'm already tried to change permissions using chmod,chown,acl, windows gui, windows consol gui. And I can change permissions to sub-folder but it seems thatit doesn't work and only groups added to samba-share worked for me and also for sub-folders


I print here all my smb.cfg and a single test share:

# No .tld
workgroup = DOMAIN
netbios name = samba4
server string = %h server (Samba, Ubuntu)
# Active Directory System
security = ads
# With .tld
# Just a member server
domain master = no
local master = no
preferred master = no
dns proxy = no
# Disable printing error log messages when CUPS is not installed.
printcap name = /dev/null
load printers = no
printcap cache time = 0
#additional section
obey pam restrictions = yes
map to guest = bad user
dns proxy = no
vfs objects = acl_xattr
map acl inherit = yes
nt acl support = yes
acl map full control = yes
#acl compatibility = auto
store dos attributes = yes
map archive = no
map hidden = no
map read only = no
map system = no
# Works both in samba 3.2 and 3.6.
#idmap backend = tdb
# no .tld
idmap config * : backend = tdb
idmap config * : range = 10000-99999
winbind enum users = yes
winbind enum groups = yes
# This way users log in with username instead of username@example.com
winbind use default domain = yes
# Inherit groups in groups
winbind nested groups = yes
winbind refresh tickets = yes
winbind offline logon = true
#winbind separator = \
# Becomes /home/example/username
template homedir = /home/%D/%U
#logon drive = H:
#logon home = \\smb\%U
# No shell access
template shell = /bin/bash
client use spnego = yes
client ntlmv2 auth = yes
#password server = dc01.domain.local, dc02.domain.local

vfs objects = full_audit
full_audit:success = mkdir rmdir unlink pwrite
full_audit:prefix = %u|%I|%m|%S
full_audit:failure = none

        read only = no
        inherit acls = yes
        inherit permissions = yes
        create mask = 700
        directory mask = 700

└──╼ #ls -ld test\$/
drwxrwx---+ 6 root root 4096 Jun 25 15:44 test$/

ACL configuration:

cat /boot/config-4.4.0-87-generic  | grep _ACL

My fstab:

UUID=4ec48dfe-c45d-124b-8145-09fe59cfad9b /FS ext4 relatime,acl,user_xattr,errors=remount-ro 0 1

In samba.log I see a problem with acl permission while I try to change permission to test directory

set_nt_acl: failed to set file acl on file test (Operation not permitted).

Also I change permission on test directory to 777 and delete options "create mask", "directory mask", "admin users". Now I can't even add new user to file permission

  • Have you tried what you're wanting to do? At a quick glance it seems that there's nothing wrong. Please edit your question to explain what you've tried and what did - or didn't - work when you tried it. – roaima Jun 26 '18 at 8:30
  • #ls -ld test\$/ drwxrwx---+ 6 root root 4096 Jun 25 15:44 test$/ – Vladyslav Greyswandir Jun 26 '18 at 9:48
  • Also I edit my post – Vladyslav Greyswandir Jun 26 '18 at 9:49
  • Ok, I add ls output in the bottom of the code section – Vladyslav Greyswandir Jun 26 '18 at 9:56

If you wanting to use Windows permissions you need to remove the UNIX/Linux permission controls that override them.

chmod 777 '/FS/test$'

Remove these lines from your share definition:

create mask = 700
directory mask = 700
admin users = ...
  • Thank you for answer, but after many tests, this not worked for my case – Vladyslav Greyswandir Jul 10 '18 at 7:33
  • @VladyslavGreyswandir still what didn't work? What did you try? What results did you get? What do the logs say? – roaima Jul 10 '18 at 7:53
  • Sorry for waiting. I have the same problem as described in post. I change permission on test directory to 777 and delete options "create mask", "directory mask", "admin users". Now I can't even add new user to file permission. I think that some directive can block this feature, but I don't know which. I reed a lot about all directives specified in my configure file but still no progress in this case . Also I try change folder permissions only from Windows explorer – Vladyslav Greyswandir Jul 17 '18 at 8:52
  • @VladyslavGreyswandir how are you mounting the share? – roaima Jul 17 '18 at 10:19
  • I use AD GPO or smb4k(for linux) or simple create Windows shortcut with all available shares inside – Vladyslav Greyswandir Jul 17 '18 at 10:46
