[Samba] Enabling NIS after samba4 installation

[Michael Brown]

I'm testing out our samba 4 migration process and when the initial 
forest/domain was created, it was created without using --use-rfc2307:

sudo samba-tool domain provision --domain netdirect 
--function-level=2008_R2 --realm=ad.netdirect.ca

Now that it's in place and we have machines joined, what do I need to do 
to add the unix attribute and NIS maps to an existing samba4 domain so 
that we can use the rfc2307 features?
