That should work.

If you are logged into the Windows machine as 'INTERNAL\Administrator'
it should work, but if you are using another Domain user, add that user
to the 'Domain Admins' group.

root@machine253:/etc/samba# getfacl /server
getfacl: Removing leading '/' from absolute path names
# file: server
# owner: root
# group: root

Something is going on here, 'ls' shows 'root:domain admins' as the
owner:group with 0770 permissions, but getfacl shows 'root:root' as
owner:group with 0755 permissions

I ran this command from the Debian section of the
"Distribution specific Package Installation" on the wiki.

# apt-get install samba attr winbind libpam-winbind libnss-winbind
libpam-krb5 krb5-config krb5-user

'acl' is installed by default

Foe it's worth, Group policy is mapping the drives and the
various shares are being restricted to the proper groups.
I can also set folder/directory permissions on the share
by navigating directly to the share using a UNC path.


Just know that the last part of the "Setting Share Permissions
and ACL's" on the wiki doesn't allow for anything to be
modified on the 'Security' tab.

It should and I have just updated that wiki page.

Not sure if this is "as designed" or did I do something
which will create problems later.

Double check Unix ownership and permissions on the share directory,
that is really the only thing that looks wrong.
To remove the ACL's and start again, run:

What exactly does "START AGAIN" imply? Just chmod?

setfacl -b path/to/directory

reset the unix permissions as shown on the wiki page and then try again
from Windows.
