Hello, 

I use ACLs on ext3 Filesystem.
When I create a File on the Linux-box the Samba-server runs on and I change the permissions that "everybody" has no access like
# chmod 740 
I am able to modify the file on a Windows-box and the permission for eveybody does not change. 
But when I change the ACLs with the Windows internal ACL-editor or I create a new file directly on the Windows-box allways the read-permission-bit for everyone is set and can't be revoked by the ACL-editor.
When I revoke it on the commandline on the Linux-box like
# chmod 740 
and I reopen and save the file on a Windows-box the old permissions where set again.

The share-Definition is:
[Documents]
        comment = Dresearch Internal Documents
        path = /srv/samba/data/Documents
        browseable = yes
        read only = no
        guest ok = no
        acl group control = yes
        map acl inherit = no
        inherit acls = no
        inherit owner = no
        inherit permissions = no
        admin users = DRESEARCH/Administrator
        writable = yes
