Looking for a Guide for pfSense 2.4.3 + FreeRADIUS 3.x + LDAP

[quriel]

Hi to everyone,

I'm for the first time try to setup on pfSense a captive portal (on a vlan) based on FreeRADIUS autentication integrated with LDAP.
The FreeRADIUS service are provided by the pfSense dedicated package, the LDAP are provided by a Windows Server 2016.
I'm a totally newbie  in this kind of configuration  :-[, and in FreeRADIUS in particular way… I looking around for some guide, but i have found nothing for FreeRADIUS 3.x, and I'm starting to be a little confused  :o .
I'll be thankfull of any kind of suggestion or help
