I had the same problem as stated in this thread.
Wanted to follow up with my results.

Server:
CentOS 7.1503
Version 4.1.17-SerNet-RedHat-11.el7

Windows 8.1 Pro x64.
Updated through May 6/2015.
RSAT tools installed:  Windows8.1-KB2693643-x64.

Initial testing trying to create a new user in Samba 4 provisioned domain.
Logged in as Administrator -->
open Administrative Tools -->
Active Directory Users and Computers --->
internal.example.com  --->
Users container -->
Create a new user in current container failed with error:
An error occurred. Contact your system administrator.

Per the linked thread, I uninstalled Windows Updates KB2992611 and
KB3000850 and restarted Windows client.

Tried again to create and configure a new user in the Users container and
now works.

I need more review to understand the Windows Updates and the "fix" provided
by them, but removal appears necessary to unblock options needed in Windows
Admin Tools --> Active Directory Users and Computers.
