[Samba] Roaming Profiles acls after upgrade

[Mark Nienberg]

We recently upgraded our samba 3.6 network to samba 4.2.3. It is still a
NT-style domain.
The underlying OS was upgraded from CentOS 5 to CentOS 7.

The profiles share is set up like this:

[profiles]
        comment = Roaming Profiles
        path = /mnt/share2/ntprofiles
        browseable = no
        writable = yes
        csc policy = disable
        create mask = 0600
        directory mask = 0700
        admin users = +ntadmins

I noticed that the directory mask is being ignored for new profiles and
filesystem acls are being added instead.
Compare these two directories where the first one was existing before the
update and the second one is post update.

drwx------  14 fuko      Everyone 4.1k Jan 25 12:08 fuko.V2/
drwxrwx---+ 14 gauthier  Everyone 4.1k Jan 21 17:01 gauthier.V2/

Here are the added acls:

[root at geckovm ntprofiles]# getfacl gauthier.V2/
# file: gauthier.V2/
# owner: gauthier
# group: Everyone
user::rwx
user:gauthier:rwx
group::---
group:Everyone:---
mask::rwx
other::---
default:user::rwx
default:user:gauthier:rwx
default:group::---
default:group:Everyone:---
default:mask::rwx
default:other::---


In the [global] settings we have this:

map archive = no
map hidden = no
map read only = no
map system = no
store dos attributes = yes
create mask = 0770
directory mask = 0770
acl allow execute always = True


Everything still works fine, but it is a little harder to understand and
administer.
Is this the intended behavior?

Thanks, Mark
