I have successfully setup LDAP module to authenticate users (and create new users). This is done through manual login form. Now I'm trying to enable automated single sign-on, but with no luck.
I have enabled LDAP SSO, and selected Turn on automated single sign-on.
On IIS, I've enabled Windows Authentication (Anonymous is still enabled).
I do not get automatically logged in, it returns error msg "You were not authenticated by the server. You may log in with your credentials below".
What else needs to be configured in a Windows environment to enable SSO?
Does anyone have any insight on what the reference info is talking about, when the say "This requires that you have operational NTLM or Kerberos authentication turned on for at least the path /user/login/sso, or for the whole domain" ? Other than looking at Windows Authentication on IIS, enabled providers = NTLM, what else needs configuring?
