samba - Sep 2013 - Thunderbird 24.0 for Windows seems to ignore Samba4.0.9 permissions settings

Hi,

I have a CentOS 6.4 fileserver running SerNet Samba 4.0.9 with these 
global settings (not overridden):

         read only = No
         force create mode = 0777
         force directory mode = 0777
         inherit acls = yes
         inherit owner = yes
         inherit permissions = yes

On a Windows client, I have Thunderbird 24.0 storing its profile and 
mail on the Samba share.  The perms on everything in the share were 
chmod -R 777'd.

Then I get mail, compact a folder, whatever, and it looks like this:

Whatever it touches is now 770.  How can that be, when the parent of 
this folder is 777, Samba is set to inherit and force 0777?  Is this 
Samba misbehaving, or Thunderbird?

Thanks,
Kev

It looks like the you have acl's active, hence the + after the 
permissions rwxrwx---+ .
These acls overrule the local permissions set by samba.

Not samba not thundebird is misbehaving.
