      Hi,
      I've seen several threads about his topic but currently i catched no final solution or statement the it won't work. My scenario:

      • pfSense 2.5.1
      • Microsoft 2019 Server as DC

      Current status:

      For preliminary testing purpose I have configured under Authentication Servers LDAP with SSL and memberOfgroup against the MS AD Server. Works! At least with testing on the pfsense under: Diagnostics=>Authentication

      So I would like to have this working using the freeradius + LDAP against the same MS AD Server.
      My radius.log shows the following when trying to authenticate:

      As far as I understand:

      • LDAP connection and binding => OK
      • LDAP search for the reuqested user => OK
      • Authentication for the User => NOK

      my research points to something with PAP/NTLM Auth-Type, etc., etc. - and maybe something to adjust in the radius configuration.
      Also read something to use SAMBA for NTLM Auth, but all in all I am confused.

      So any suggestions are welcome.

      Kind regards
