There is a reason why it doesn't work, you appear to be using one of 
Jeremy's git branches where he is working on SMBv3 Unix extensions. The 
operative word is 'working', they do not work yet, so I wouldn't use the 
branch unless I wanted to test where he had got to 😁

I suggest you wait until the required patches are finished and have been 
accepted into Samba master.
