Bug Description
Since the upgrade from 4.1.6 to 4.3.8 on our Samba domain controllers on Ubuntu 14.04, clients fail to connect. Tested with Windows 7, Windows Server 12 and Samba clients.
$ smbclient -L dc01 -U Administrator
session setup failed: NT_STATUS_
In the server logs I see:
smbd[20632]: [2016/04/21 21:05:43.093606, 1] ../source3/
smbd[20632]: Failed to generate session_info (user and group token) for session setup: NT_STATUS_
The Windows clients cannot access shares and (quite critically) the RSAT tools such as ADUC can't be used to manage the domain.
May be related to bug #1572301 where issues from other client platforms are reported.

I noticed that after the update to 4.3.8 my smbd would not run at all.
testparm gave me this:
Load smb config files from /etc/samba/smb.conf
rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384)
WARNING: Ignoring invalid value 'share' for parameter 'security'
Error loading services.
smbd would stay running with a barebones config, so I started trimming away at mine until it worked. It turns out that removing the line:
security = share ;
fixed my problem, even though it was supposedly being ignored.
