Hi
Does anyone know if its possible for a PPPoE server to ignore the password from the client device and authenticate it?
Cheers
Ged

AFAIK, it's not possible. RADIUS should do that. why do you need this behaviour?

I'll see what I can do with Radius.
We are cutting over customers from anothe DSL provider to our own DSLAMs. It saves us configuring the customers routers if we can ignore the old passwords.

You'll be able to do this with FreeRadius and a custom Shell/Perl/Pyhton script (rlm_exec, rlm_perl, rlm_python)
Simply ignore the request received, and always return auth success. It won't however work with encrypted passwords (CHAP, MSCHAP) and due to how those authentication protocols work, it will never work, and is impossible to do. You will therefore only be able to do this with PAP authentication.
