5 beta 13 & Active Directory

I recently did a clean install of beta 13 from 4.7 and am now having trouble with the Activity Directory integration.

I backed up my 4.7 configuration and reformatted my USB key and copied over the beta 13.  After successfully booting I executed the Utilities/New Permissions script to reset ownership of the content on the drives to nobody:users.

According to the SMB profile under the settings the system successfully joined the domain however when I execute:

getent passwd or getent group I do not see any of the AD users/groups like I did in unraid 4.7.

Executing wbinfo -u or wbinfo -g does return the correct list of AD users.

Initially when i setup AD with unraid 4.7 I had to edit the domain security policy to change the authentication method:

Network security: LAN Manager authentication level
Set to: Send LM & NTLM responses

Minimum session security for NTLM SSP
Disable Require 128-bit encryption

Changing these settings allowed Windows 7 clients to properly connect to the network shares.

Additionally can someone help clarify if it is still necessary to change the owner/group of the shares to an Activity Directory user/group to enforce domain security?

In 4.7 I was able to limit access by issuing chown -R "mydomain\myuser"."mydomain\mygroup" /mnt/user/myshare
