@wickeren said in Freeradius with LDAP backend and 802.1x: Have set Active Directory Compatibility in the Freeradius LDAP settings and played around with the EAP settings. For now the default is PEAP, in the EAP-PEAP section the default is MSCHAPv2 and Copy Request to Tunnel is set to Yes. According to some info I have found this should be OK, but in my case it isn’t however. Still think it must be something there, but can’t figure it out yet. Hi , I tried to configure free-radius on Pfsense (authentication via ldap or Kerberos) , i have AD 2008 . can you share your configuration please
