SSO NTLM on Windows 2012 R2 ISS 8

Hello, You have mentionted that you support NTLM SSO from version 2.0.11 (currnet version is 2.0.10) Ref: https://active-directory-wp.com/docs/Getting_Started.html
But you already have som manual how to configure it (https://active-directory-wp.com/docs/Networking/Single_Sign_On/SSO_with_IIS_on_Windows.html)

Do you have some solution? I followed manual (using REMOTE-USER) but it doesnt work for me.
Thanks
