[Samba] Join to existing 2012R2 fails

[Michael Howard]

I thought v4.12 was compatible with Windows Server 2012R2? I built from 
source with a simple ./configure && make.

I can't join to an existing (Windows 2012 R2) domain unless I lower the 
functional domain and forest levels to 2008R2. With 2012R2 I get;

DsAddEntry failed with status WERR_ACCESS_DENIED info (8567, 
'WERR_DS_INCOMPATIBLE_VERSION')
Join failed - cleaning up

Am I missing something?
