Ahh, CentOS is forcing hidden dependency on its ssd package - that's naughty!!!

SOLUTION (install sssd-libwbclient) : ```

[adm@myhost ~]$ sudo yum install sssd-libwbclient -y
.. etc ...                                                              
Installed:
  sssd-libwbclient.x86_64 0:1.16.2-13.el7_6.5                                                                                 
Complete!

[adm@myhost ~]$ systemctl restart smb
