we attempted to update the freeradius from version 2.x to 3.2.6. We copied the existing configuration(clients.conf, radiusd.conf etc) to the freeradius installed on the new Linux system.
That won't work. The configuration is similar, but not identical. You can't use exactly the same configuration across major version changes.
In testing, there were no issues with PPP that directly requests authentication from the cpe to the radius server.
However, L2TP authentication that passes through another company's proxy radius encounters an error. The error message is as follows.
Auth: (207) Login incorrect (chap: &control:Cleartext-Password is required for authentication): [eurogarage-puilboreau-002@ven.axess.ptel] (from client PhibeeProxy2 port 16777956)
There is debug output which will get you more information. Perhaps try that? Alan DeKok.
