Yes, red-hat promote sssd, because it is their package. I don't
actually think it is the best method for authentication on a Samba
machine. Are you also aware that sssd uses a version of a winbind lib ?
So why not go the whole way and use winbind, this will get you a fully
supported by Samba set up.

You should have asked here earlier, I can guarantee that you would have
had a working system (with winbind) well inside your three weeks.

The only user you should map to 'root' is 'Administrator'.
Does your OS know your user, i.e. does 'getent passwd admin' return
anything ?

If you want to use winbind, then I am prepared to try and help you get
it working, if you insist on using sssd, then I repeat, sssd is not
supported by Samba, it is not a Samba product, so you will have to seek
help through the sssd-users mailing list.
