[Bug 1592326] [NEW] Permissions not inherited by files

[Dariusz Gadomski]

Public bug reported:

Samba version used:
4.3.9+dfsg-0ubuntu0.16.04.2

Steps to reproduce:
1. Configure a samba share with inherited permissions:
[share1]
  path = /srv/share1
  browseable = yes
  read only = no
  guest ok = no
  inherit permissions = yes
2. Create a directory under that share:
cd /srv/share1; mkdir inherit && chown 2770 inherit

3. Connect to this share from a Windows client and create a file and a
folder in the new directory.

What is expected?
Both file and directory have permissions inherited from the parent directory.

What happens?
├── [drwxrws---] ./inherit 
│   ├── [-rwxr-----] ./inherit/New text document.txt 
│   └── [drwxrws---] ./inherit/New folder 

File has not inherited the group-write permission.

This should not be the case according to the manpage 5 smb.conf:
New files inherit their read/write bits from the parent directory.

In this case the containing folder group write permission has not been
inherited.

The inheritance worked as expected in 4.1.6.
