An observation: The instructions seem to only cover winbind. As an example, it says to use the "ntlm_auth" command. That command is not part of sssd. Is there a newer version of that guide page that uses sssd instead of winbind ?

If you want users to come directly from AD, then you can add winbind. If instead you use sssd for users, and it connects to AD, then just list "sss". Alan DeKok.
