Description Dariusz Gadomski 2016-06-14 09:20:24 UTC
With the following share definition:
  path = /srv/share1
  browseable = yes
  read only = no
  guest ok = no
  create mask = 0770
  force create mode = 0660
  directory mask = 2770
  force directory mode = 2770

I create a directory:
cd /srv/share1; mkdir modes && chmod 2770 modes

There from a Windows client I connect to the share and create some files & directories:
New text document.txt*
New folder*

Entries marked with * have their default names (picked by Windows) untouched.

Here is what happens:
└── [drwxrws---] ./modes 
├── [-rwxr-----] ./modes/New text document.txt 
├── [drwxrws---] ./modes/New folder 
├── [drwxrws---] ./modes/test 
└── [-rwxrw----] ./modes/test.txt

Despite force create mode the "New text document.txt" does not have group-write permission, while another file with custom name has the permissions set as desired.

When I rename "New text document.txt" to anything else the permissions are fixed immediately:
└── [-rwxrw----] ./modes/test2.txt

This was not observable with Samba 4.1.6.
