How do I install samba on RHEL 7 Desktop

I am trying to install samba on my RHEL v7.2 install (as I have for my previous v6 install) and it is not a listed yum package and no one in support seems to be able to help.

Is this still an available package or have they taken it out of the desktop v7 system?

Which repository is it in and which yum install command do I use to install it.

Thanks,

George
