I am able to easily add a CentOS 7 box to an active directory network.
It is extremely easy, so much easier than running setup or editing
Basically
yum install sssd realmd oddjob oddjob-mkhomedir adcli samba-common samba-common-tools krb5-workstation openldap-clients policycoreutils-python -y
Then add to the domain using
realm join --user=administrator example.com
Make sure domain and DNS is correct.
Went to PT today, they are starting to push.
