I'm using Freeradius to authenticate VPN clients using PPTP or L2TP/IPSec (xl2tpd) and I want to do an upgrade from Debian 8 to 9 on our servers incl. upgrading version of Freeradius (2 -> 3).
Both PPTP and L2TP are using radius.so plugin in their ppp configuration to authenticate users against Freeradius. However this plugin is not working with freeradius client libradcli4 and other older clients (like libfreeradius-client2) are deprecated in Debian 9.
New libradcli4 has different path for config files (older /etc/radiusclient/ vs /etc/radcli/), unknown attribute types, e.g. ipv4addr in dictionary, missing port-id-map file etc.
Is there any working non-deprecated radius client, newer radius.so plugin or proper way to get this working?
Thank you
