howto run logon script on samba 4?

I have to make a script insamba 4 that must run on windows client. When a user logon in his computer the web page has to be the intranet page of the company. The script must alter the initial page, when the user open the webbrowser the page that must be showed is the intranet page.

I could do that on samba 3 working on smb.conf netlogon option, and than put the script on the directory netlogon.
But now I can´t do this anymore. I made researches on internet and saw that I have to use microsoft AD, that I have to install rsat ou something like that.
I am totally lost.  
Could anymore help? But please, give me details, not just saying general things.

you can add this to your logon script--the first is for firefox and the second for IE
"C:\Program Files (x86)\Mozilla Firefox\firefox.exe" or
"C:\Program Files\Internet Explorer\iexplore.exe"
