using here dokuwiki Greebo stable running on Ubuntu 18.04 with the authAD plugin. It works really fine. So now i would to configure SSO. Which is not entirely clear to me now... The documentation https://www.dokuwiki.org/plugin:authad#web_server
say you should configure NTLM and Kerberos for Apache.
And should mean it really "and" or should mean it "NTLM or Kerberos". It is not clear for me.
Very Thanks and best regards :)
