[Samba] RHEL7/Centos7 with Samba AD

[vincent at cojot.name]

Hi Nico & all,

I'm currently updating my samba4 rpms to 4.8.8 and I noticed that I needed 
to add a new (not in 4.8.7) dependency to my spec file:

%{_libdir}/samba/libcmdline-contexts-samba4.so

(not too sure in which rpm to add that one but I guess I'll see how it 
goes).

Where's your samba-4.8.x spec rpms tree? Is this:
https://github.com/nkadel/samba-4.9.x-srpm/tree/nkadel-4.8.7

Once I figure out how to consume your repo, I'll probably submit a PR. :)

Thanks,

Vincent
