[Samba] Fix for Windows 8.1 RSAT error when creating users
I created a new Samba4 AD DC, and attempted to add users and groups from a Windows 8.1 computer using the Remote Server Administration Tools. While I was able to create groups just fine, attempting to create a user failed with the message "An Error Occurred. Contact your System Administrator." A quick Google shows that others on this list have had this and similar problems, but I was unable to find a satisfactory solution here. I thought you might be interested in what worked for me. According to Microsoft, there is a known issue with a Windows Update which may appear as KB3000850 or KB2992611. Others have suggested removing this update, which may or may not be practical. However if you look at http://support.microsoft.com/en-us/kb/3000850 in the "Known issues in this update" gives a registry hack fix. In regedit, under the key " HKEY_LOCAL_MACHINE\Software\Microsoft\Cryptography\Protect\Providers\df9d8cd0-1501-11d1-8c7a-00c04fc297eb", create a DWORD entry with name "ProtectionPolicy" and value "1". After a reboot, this fixed the problem for me. --Dan Menes

If that doens't, then remove the pointer to the preferred backupkey (so we regenerate one correctly with a 2048 bit key), per the ldbdel suggestion here: https://lists.samba.org/archive/samba/2014-November/187205.html> According to Microsoft, there is a known issue with a Windows Update > which may appear as KB3000850 or KB2992611.
