Cannot access samba shares from a server running inside LXC4....but can inside LXC3 :(

Hello all,

I am running samba server inside a container on lxc-4.0.5 that i am able to login into a share but not see the contents:

# mount -t cifs -o username=user [//172.16.0.100/USER](https://172.16.0.100/USER) /mnt/tmp
Password for user@[//172.16.0.100/USER:](https://172.16.0.100/USER:) **************
# cd /mnt/tmp/
# ls
ls: reading the directory .: Permission Denied.

However, when i run the exact same container, with exact the same config file - on a lxc-3.2.1 - i am able to see the content of the share.
I have no apparmor running, or FS acl. Please note that the SMB Server is inside the container and i am so wary right now about this that is running in privileged mode.

# mount -t cifs -o username=user [//172.16.0.100/USER](https://172.16.0.100/USER) /mnt/tmp
Password for user@[//172.16.0.100/USER:](https://172.16.0.100/USER:) **************
# cd /mnt/tmp/
# ls
total 9
drwxr-xr-x 2 user users 4096 Abr 10 15:54 .
drwxr-xr-x 7 root root 4096 Abr 10 15:53 ..
-rw------- 1 user users 51 Abr 10 15:54 dummy_file.txt

From what i gather it appears to be related with permissions with LXC3 vs LXC4.
What am i missing? Can you help me please?

Thanks.
