Cannot access customized samba share

I still have this problem after update 4.4.4-14…
Would appreciate any help

As suggested by

and

a little more info would help.

Hi sorry for lack of details.
Don’t see any special errors in samba logs.
The last version that works is 4.4.4-12. in 4.4.4-14 it is still not fixed.
The problem exists in Windows XP and Windows 7.
When “follow symlinks” is set to no (this is what I need - I want to prevent access to symbolic links)
In windows xp any directory under /data is seen as empty
In windows 7 any directory under /data is inaccessible.
Seems like it regards everything under main share as a symbolic link.

smb.conf:
[global]
workgroup = WORKGROUP
server string =
netbios name = ims-db
security = user
map to guest = bad user
dns proxy = no
#============================ Share Definitions ==============================
[data]
path = /data
valid users = @smbgrp
guest ok = no
writable = no
read only = yes
browsable = no
create mask = 0755
force user = root
follow symlinks = no

cat /etc/centos-release

CentOS Linux release 7.3.1611 (Core)

This share definition is not from NethServer. I don’t know how to help because I don’t know how this system is configured!
