To my understanding if this is configured correctly when you visit the site you are not required to register or log in. It will use your current windows authentication? Kinda like when you open up your sharepoint site. If so I'm not sure what Im doing wrong. When I visit my test setup it asks for my windows login (because I have windows authentication turned on in IIS) then I am asked to log in again at the top, I use my domain credentials and I can get in. What am I doing wrong?
Windows 2008 Server
IIS 7.5
PHP/fast CGI
MySQL
Moodle 2.9
LDAP is turned on obviously, and NTLM SSO is on
