[Samba] Can Logon & Join NT4-style Domain, Can't Change Password

[Stephan Roth]

The following article by Microsoft was updated on 2016-10-14: https://support.microsoft.com/en-us/kb/3167679

It acknowledges the problem and proposes to set a registry key to enable NTLM authentification. Fot the details see paragraph "Known issue 7" in the article linked above.

- Under "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Lsa"
- Create the key "NegoAllowNtlmPwdChangeFallback" and set its value to 1

So far it works on some of our machines, we haven't tested it extensively.
