This looks all good to me but the problem lays in the DC winbind code, not the member. 

You can try to witch back ( temperarly ) to winbind ( on the DC ) 
As i did, al least you get the correct id's back. ( for now ) 
For you this the change you need on the DC. 

server services = -winbindd +winbind

Im recompiling the samba 4.3.3 from sid now atm, so ill test them out what happpens. 

I'll report back here. 

Greetz, 

Louis
