That howto seems to have been dated even when it was written and you
haven't added all the 'recommended options'.
The howto tells you to add these lines:

 idmap uid = 16777216-33554431
 idmap gid = 16777216-33554431

These were marked as deprecated on 3.6 and you should be using lines
like these:

    idmap config *:backend = tdb
    idmap config *:range = 2000-9999
    idmap config SAMDOM : backend = rid
    idmap config SAMDOM : range = 10000-999999

Without these lines, winbind doesn't know who your users & groups are.

Or are you using sssd ?
If so, then Samba isn't doing authentication.
